Talk:Carl Hewitt

User page = Page about you

Isn't this kind of odd? Your user page redirects to a page about you? It's indirection I guess, but I'm not sure this is something that should be encouraged on Wikipedia. For example User:Lumidek (though no shining example of Wikipedia civility, he) who is known to be Lubos Motl maintains a distinction between the two pages. --CSTAR 04:36, 20 July 2005 (UTC)

Good point. I was just trying to connect the two pages. So I changed it to "See Carl Hewitt".--Carl Hewitt 05:08, 20 July 2005 (UTC)

This is still weird. I can't figure out if the encylopedia page about you is your user page or your bio or what (I assume you're not looking for another job). I really find the WP lynch mob disgusting, but you really have to be more sensible, and try to separate yourself from your contributions to WP. Why on earth do you have an abstract from a talk you gave 5 months ago? This is really looks like a case of self-promotion and that's a big no-no on WP. See Florentin Smarandache a grand self-promoter.

If you don't remove the abstract to your talk, soon, I will. --CSTAR 22:11, 18 September 2005 (UTC)

Previously, the page had a link to the abstract of the talk. Unfortunately, the link to the abstract died and someone requested that it be restored. So I restored it. Now the question is what to do. Should some of this be reported in a Wikipedia article? Would it be better to put this in a user talk page as some have suggested? I agree that it doesn't really belong in the page about me.--Carl Hewitt 05:03, 19 September 2005 (UTC)

Most of the article is OK, although I suggest it refer to Hewitt as opposed to Carl. Moreover that abstract is innappropriate. Please remove it. The article might also give some informsation about birthtdate, place of birth etc (optional of course). Other info such as you're a student of Pappert Ph. D. 1971 (BTW I got my PhD at that awful place down the street, on the T stop between Central and Porter, just a little later).--CSTAR 05:10, 19 September 2005 (UTC)

:Thanks for your suggestions. I moved the abstract to the talk page (below). So now at least it is not part of the article. Also I changed "Carl" to "Hewitt" as per your suggestion. BTW when I was an undergraduate at "Tech", my classmates sometimes referred to the other place as "Upchuck river community college"!?--Carl Hewitt 17:52, 19 September 2005 (UTC)

Affiliation

You are not one who can pretend to be coy, Carl, so please tell us precisely what your affiliation was. I just tried to google and to my surprise cannot find you listed anywhere in any of the UM campuses, in any department. Usually retired full professors are listed somewhere as emeritus faculty. Can you please clarify this? If your uni is anything like mine, you can keep a home page in your departmental directory, which could be useful for any non-CS-er trying to quickly spot check your affiliation. Which I'm not questioning, but why make me do all this detective work? All you need do is to state Hewitt was on the faculty at UM, SomeCampus, from 19mm to 19nn. He retired with the rank of Prof. in 19qq. TIA for this information ---CH (talk) 11:17, 25 September 2005 (UTC)

I know some of you guys are uncomfortable with the article, but maybe it's good to keep your tone down and show some respects...at least a comment like this should be based on more careful google search. This link http://www.eecs.mit.edu/faculty/index.html#h shows Carl Hewitt IS a associate professor emeritus at EECS department of MIT.

Deletion of notice for talk

I deleted a notice placed by User:CarlHewitt on a scheduled talk at Stanford for two reasons

1. It is self-promotion. This is clearly a violation of WP policy.
2. At the time it was posted, it was about an event to take place in the future.

Aside from any issues of policy, it is extremely bad judgement to use an encyclopedia article as a private notice board. If you want to advertise a talk, please do it on your user page. --CSTAR 20:32, 13 October 2005 (UTC)

I removed the links to his user talk page as well. --R.Koot 12:25, 19 October 2005 (UTC)

Archive?

Some of the stuff here is old and should be archived. How is this done? Thanks,--Carl Hewitt 03:37, 31 October 2005 (UTC)

All of the stuff here is not old. Even if it was it would not be necessary to archive, since the page is very short. --R.Koot 03:49, 31 October 2005 (UTC)

Is advertising a talk appropriate use of a talk page?

Is it really appropriate for User:CarlHewitt to use an article talk page to advertise an upcoming seminar presentation? For example, I would go ballistic if say William Dembski used the talk page of the WP article on him to promote talks on Intelligent Design. Hewitt is setting very bad precedent here, in my opinion. --CSTAR 00:15, 5 November 2005 (UTC)

I put it in external links at the suggestion of another Wikipedia editor.--Carl Hewitt 01:48, 5 November 2005 (UTC)

It's still advertising.--CSTAR 04:58, 5 November 2005 (UTC)

At least it's an external link. We have all sorts of stuff in external links.--Carl Hewitt 05:16, 5 November 2005 (UTC)

What I meant was that you should put an external link to your homepage (e.g. www.mit.edu/~hewitt) in the article, not a link to an advertisment on the talk page. --R.Koot 12:04, 5 November 2005 (UTC)

I don't think any of this is a good idea. What will prevent anyone from writing links to their webpages? --CSTAR 15:00, 5 November 2005 (UTC)

Well anyone does not have an article about him/her on Wikipedia for starters. But if someone does (e.g. Jan_Marijnissen) an external links to his/her homepage is usually provided. To User:CarlHewitt: we do not have "all sorts of stuff" in external links, see WP:EL. --R.Koot 15:33, 5 November 2005 (UTC)

According to WP:EL, linking to your own web site is strongly discouraged. The Wikipedia is supposed to have comprehensive reporting on the published literature so we ought to be able to report this published material somewhere even if it is only an external link.--Carl Hewitt 17:28, 5 November 2005 (UTC)

Concurrent computing

Discussion moved to User_talk:CarlHewitt#Concurrent Computing (moved from Talk:Carl Hewitt)

Not banning intellectuals and scientists (proposed language)

• Dear Carl, thanks for standing up for objectivity and accuracy. Since you mentioned my work, I wish to make it clear (as it can be seen in the 1st deletion bid archive) that I have suggested to offer my corrections and new related publication material to an objective editor (even if he/she disagrees with my conclusions). To date no-one has accepted to act in that capacity. Sadly, this leads to my inability to correct the obvious errors in the article, which then causes more confusion about what I have actually claimed. I suggest that we start a process of asking qualified editors to act as "official editors" of the page, so that their edits remain as the more reliable portions of the article. While non-official editors can still edit the article, their input should be closely and promptly monitored to ensure accuracy. I hate self-promotion (and have never acted in that manner), but I hate disinformation and lies even more. I believe truth does not require salesmen; it simply sells itself. Best regards. Prof. Afshar 09:00, 21 January 2006 (UTC)

References vs. Citations

DBLP has a very incomplete list of publications. The article should now be expanded to include a citation for every reference.--2ndMouse 09:46, 29 March 2007 (UTC)

Deleted content

In our opinion, the content below should be restored to the article.--LelandStanford 19:17, 7 May 2007 (UTC)

Hewitt's work on Planner introduced the notion of the "procedural embedding of knowledge", which was an alternative to the logical approach to knowledge encoding for artificial intelligence pioneered by John McCarthy (Minsky and Papert [1971]). A subset of Planner called Micro Planner was implemented by Gerry Sussman, Eugene Charniak and Terry Winograd (Sussman, Charniak, and Winograd [1971]). It was used in Winograd's famous SHRDLU program, and Eugene Charniak's natural language story understanding work. (Minsky and Papert [1971]) At Edinburgh, Julian Davies implemented essentially the whole language (Davies [1973]).

Hewitt's first publication was with Manual Blum proving impossibility results for automata on a 2-dimensional tape (Blum and Hewitt 1967). Using program schemata in collaboration with Mike Paterson, Hewitt proved that recursion is more powerful than iteration and that parallelism is more powerful than recursion. Using participatory semantics, he proved that coroutines are more powerful than recursion and that Concurrency is more powerful than parallel coroutines.The Ultraconcurrency Revolution in Hardware and Software

The work of Hewitt et. al. on the Actor model built on Lisp, Simula, capability-based systems, packet switching and Smalltalk '72 , and was influential in the development of the Scheme programming language In collaboration with Henry Baker, he published physical laws for computation which they then used to derive the continuity criterion for computable functions of Dana Scott.

Together with Bill Kornfeld, he developed the Scientific Community Metaphor. He has also made contributions in the areas of garbage collection, programming language design and implementation, primitives for structured concurrent programming (Atkinson and Hewitt [1979]; Hewitt, Attardi, and Lieberman [1979]), Organizational Computing (Hewitt and Inman [1991]; Hewitt [2007]), negotiation (Hewitt and Manning [1994]; Hewitt [1996]), logic programming,, denotational semantics of concurrency, and paraconsistent logic (Hewitt [2007]) with his students and colleagues. Work on the Scientific Community Metaphor led to academic work on the characterization and development of Open Systems (Hewitt and de Jong [1983], Hewitt [1985 1986 1990], Hewitt and Inman [1991]). Joint work with Carl Manning, led to the development of Participatory Semantics (Hewitt and Manning [1996]).

Subsequently Hewitt has worked to integrate sociology, anthropology, organization science, the philosophy of science, and Services Science into information science.

He has an interest in massive concurrency. The Ultraconcurrency Revolution in Hardware and Software

Comments

• What is your (LelandStanford's) relationship to Carl Hewitt? (And, if this "we" is referring to multiple users of the account, it should be banned and reverted. "Role" accounts are not permitted on Wikipedia. I am using "we" to refer to Wikipedia editors in the following.)
• We should only list publications relivant to the article; WP:NOT a resume service.
• We need to establish notability and verifiability of the rest of the insertions from sources other than Carl's publications and those of his students. In fact, I think the article needs to be further trimmed, rather than further expanded.
• — Arthur Rubin | (talk) 19:23, 7 May 2007 (UTC)

The professors were talking about the problems that the Wikipedia is having with persecuting academics. Some of us starting talking afterwards and we got the idea that I try making a suggestion. It sure looks like the faculty were correct!--LelandStanford 20:31, 7 May 2007 (UTC)

My take is that Carl Hewitt is notable, but primarily for his (non-falsifiable) claims about the philosophy of asynchronous computing, not about his models or theorems. I have not seen evidence to the contrary presented here before from a reliable source.

• If that is not the case, please add some sources other than his papers or his students' papers that his theories are used in the field.
• If it is the case, we need more references about how reputable scientists disagree with his theories.
• If reputable scientists don't talk about him or the Actor model, this article and the entire Actor model family of articles should be deleted.

I'm not sure which of the options is correct, or even most probable. — Arthur Rubin | (talk) 20:50, 7 May 2007 (UTC)

I think it's safe to say that both Hewitt and the Actor Model are discussed by reputable scientists. Three examples:

1. Filman and Friedman's "Coordinated Computing" devotes an entire chapter to the Actor model, and mentions Hewitt by name.
2. Robin Milner's Turing Award lecture specifically mentions both Hewitt and the Actor model.
3. Mark Miller and the folks working on the E programming language for secure distributed computing have made use of a number of ideas from the Actor model, as illustrated by the extensive references to Hewitt and the Actor model in Mark's thesis.

I'd previously included a reference to the Filman text in the article. The other references may well be worth adding, although where they'd best fit within the current detailed recounting of Carl's resume, I'm not really sure. --Allan McInnes (talk) 07:28, 24 May 2007 (UTC)

Repeated reverts by Ruud Koot have deprived people of proper credit for their work

Repeated reverts of this page by Ruud Koot have deprived people of proper credit for their work. Eugene Charniak has been deprived credit for his co-authorship of the Micro-Reference manual. Julian Davies has been deprived credit for his implementation work on Planner. Manual Blum has been deprived credit for his work on automata. Peter de Jong and Jeff Inman have been deprived credit for their work on Open Systems. Russ Atkinson, Beppe Attardi and Henry Lieberman have been deprived credit for their work on Actor serialization programming constructs. Carl Manning has been deprived credit for his work on Participatory Semantics. Depriving these people of proper credit for their work was highly unethical.--TheHoover 17:36, 12 May 2007 (UTC)

No image is preferable to a bad image

The image previously included in the article is not an encyclopedic photograph and is not appropriate for use in Mr. Hewitt's infobox. If we cannot find an appropriate photograph, we do not include a photograph. FCYTravis 23:07, 19 May 2007 (UTC)

Why is an idiosyncratic partial list of publications superior to an annotated complete list?

In addition to the highly unethical business of depriving people of proper credit for their work, why is the idiosyncratic partial list of publications being imposed instead of an annotated complete list of publications? The partial list being imposed is idiosyncratic in that one of those selected is the wrong version, the latest publication by Professor Hewitt is omitted, etc. What is the principle behind the partial selection?--64.75.137.250 00:37, 22 May 2007 (UTC)

If someone other than Carl and his students is willing to edit the article to add publications, we'd consider it. However, you are banned from editing the article. However, in general, we only list selected publications, rather than all publications which the person has co-authored or co-edited, which seems to be the way you're going. Perhaps all the publications should be removed? — Arthur Rubin | (talk) 00:51, 22 May 2007 (UTC)

Wikipedia norms versus scientific norms

The recent conflict here harks back to basic conflicts between Wikipedia norms and scientific norms. In the Wikipedia scientific experts are viewed with suspicion and barred from contributing to their areas of expertise. In this way, the Wikipedia tries to maintain a level playing field for the nonexpert. The Wikipedia stance against experts has survived so far in articles that report on well established areas. However, it seems destined to fail in areas at the state of the art where there are very few who have the expertise to participate. Censorship of experts does not seem like a viable solution long term. Perhaps the Wikipedia will adapt to accommodate expertise. In scientific communities, experts are honored and invited to contribute in their areas of expertise. Attempts are made to engage nonexperts using overviews, surveys and tutorials. Jealousy is important factor in science. Scientific communities attempt to channel jealousy in constructive directions. New research directions often have their genesis at least in part motivated by jealousy. Also there is a strong scientific ethic in properly acknowledging the work of others. The Wikipedia is still working through its jealousy issues. Lacking support for properly acknowledging the work of others is a major weakness of the Wikipedia.--64.75.224.82 19:49, 28 May 2007 (UTC)

Perhaps. Have you considered becoming an editor at Citizendium? —Ruud 20:09, 28 May 2007 (UTC)

Greatest current deficiency

Perhaps the greatest current deficiency in the article is that it doesn't include the following reference:

• Carl Hewitt. Large-scale Organizational Computing requires Unstratified Paraconsistency and Reflection Proceedings of COIN@AAMAS'07. April 23, 2007.

Could someone please remedy this? Thanks,--Prof. Hewitt 03:52, 30 May 2007 (UTC)

That paraconsistency is important is disputed. But, I suppose it could still be important that Prof. Hewitt believes it is important. — Arthur Rubin | (talk) 05:00, 30 May 2007 (UTC)

To determine the importance of the article, I would ask experts who were at the the presentation of the paper at AAMAS'07, e.g., Les Gasser, Mike Huhns, Victor Lessor, Pablo Noriega, Sascha Ossowski, Jaime Sichman, Munindar Singh, etc. Alternatively, I would ask others who have some knowledge of the work including Gerry Allwein, Jeremy Avigad, Randy Bryant, Mike Dunn, Sol Feferman, Jeremy Forth, Harvey Friedman, Mike Genesereth, Mehmet Göker, Tim Hinrichs, Bill Jarrold, Ben Kuipers, Mike Kassoff, Pat Langley, Vladimir Lifschitz, Henry Lieberman, John McCarthy, Marvin Minsky, Peter Neumann, Ray Perrault, John Reynolds, Dan Shapiro, Wilfried Sieg, Mark Stickel, Graham Priest, Pete Szolovits, Gerry Sussman, Dana Scott, Richard Waldinger, and Jeannette Wing.--Prof. Hewitt 17:42, 30 May 2007 (UTC)

Perhaps it would help if Prof. Hewitt put his complete CV/bibliography on his blogspot site (or some other site), and then helped us to identify the 5-10 publications from that list that were the most important or influential, and that should therefore be listed in the "selected publications" section. It'd be particularly helpful if Carl (or someone else) could point to a third-party source which identifies the most important publications. But such a source may not exist. --Allan McInnes (talk) 05:14, 30 May 2007 (UTC)

Unfortunately the complete CV is very long. Probably the papers that are most useful to Wikipedia users are the most recent ones. Since the research community is very fragmented, opinion as to which are the most influential would depend on who you ask. Also some people think that older papers are more influential because of the impact that they had over the years. Others think that recent papers are more influential because they have more impact on current research.--Prof. Hewitt 18:45, 30 May 2007 (UTC)

The fact that the CV is so long is the precisely the reason that we don't want to list every publication in the article. I don't know that Wikipedia has any set criteria for selecting which publications to include. Perhaps that's something worth taking up with the folks at WikiProject Biography. --Allan McInnes (talk) 19:27, 1 June 2007 (UTC)

This might help to identify influential papers. Although I think only covers publications up to around 1997. --Allan McInnes (talk) 05:20, 30 May 2007 (UTC)

I wonder if it would make sense to establish a policy of listing all the publications of each author in computer science and encouraging the community to annotate each one. This could create a valuable resource. What do you think?--Prof. Hewitt 18:34, 30 May 2007 (UTC)

I think that:

1. Such a list would, in most cases, be so long that it would overwhelm the rest of the article. Besides, Wikipedia isn't a resume service, and Wikipedia bios are not supposed to be resumes. There are plenty of other places for academics to list their complete set of publications (such as personal webpages or blogs).
2. Community annotations would most likely amount to original research, and thus be inappropriate for Wikipedia. However, I agree that a resource along those lines might be valuable. Perhaps you should consider setting up your own MediaWiki-based site, which could contain community-annotated information on various publications. Such a site could conceivably have far more extensive annotations than could reasonably be fit into a Wikipedia article.

--Allan McInnes (talk) 19:27, 1 June 2007 (UTC)

You make some good points.

1. In cases where the number of articles by an author X is long, a sub-article "Publications of X" could be created. I am only thinking of covering published articles; not resumes. Similarly, it also might be useful where there are a large number of publications on a subject X to create a sub-article "Publications on X".
2. I don't see why encyclopedia descriptions of particular scientific publications should necessarily constitute original research any more than encyclopedia articles on the scientific areas of the publications.
3. A significant problem with using some other site is that there doesn't seem to be any easy way to link (using the double square bracket notation) between an article about publications on some subject and the articles related to the subject.

--Prof. Hewitt 05:19, 2 June 2007 (UTC)

In response to 1, there are already plenty of other venues which are appropriate for containing complete lists of publications for particular author or subject. Wikipedia articles are supposed to be summaries of existing material, with pointers to further information (which might include pointers to those other venues). Providing an entire publication list seems (to me) outside the scope of Wikipedia. However, if you believe otherwise then I suggest you take it up either with Wikipedia:WikiProject Biography, or at the village pump. Debating the issue here will get us nowhere.

In response to 2, unless the "annotations" consist of a purely factual summary of the article in question with no additional opinion inserted, or a referenced commentary on the article (rare), then the material will end up being OR. Beyond that, I again have trouble seeing how such material is within the scope of an encyclopedia. As I said before, perhaps you should consider setting up your own MediaWiki-based site to provide such material. Alternatively, take the issue up at the village pump - as with the previous issue, what you are suggesting seems like something that would be better handled at a Wikipedia community level, rather than debated here.

In response to 3, that's what single-bracket http links are for. However, in general such links belong in the external links section or in the references. Again, Wikipedia is supposed to be a sourced summary of existing material, not a microcosm of the entire web. And again, these issues (if you want to pursue them further) are probably better discussed at the village pump, since they potentially involve a large number of articles rather than just the current article.

--Allan McInnes (talk) 23:19, 2 June 2007 (UTC)

This article should be deleted

Carl has embarrassed himself with this self-promoting, largely self-authored web page. Contrary to his implications otherwise, he is no longer on MIT's faculty; he has no office at CSAIL nor does he act in any official capacity. It is highly doubtful that his (exaggerated) contributions to AI were sufficiently notable to warrant an entry here. In my humble opinion, he does not meet either the standard for WP:BIO or Wikipedia:Notability_(academics). —The preceding unsigned comment was added by 151.203.18.206 (talk • contribs).

Question for Ruud Koot and Allan McInnes

Dear Ruud Koot and Allan McInnes,

Evidently you

1. Haven't read much of the specialized literature in the areas where I have published.
2. Haven't attended the scientific meetings
3. Don't know the researchers

Also, evidently, you haven't consulted widely among those who do have the above qualifications.

So how can you possibly know what is significant?Prof. Hewitt 22:18, 17 June 2007 (UTC)

Actually, I agree to some extent, except that all the editors who do not belong to the categories you list above appear to be you or your students, who are strongly discouraged from editing this article under WP:AUTO and WP:COI, and banned from editing it under an ArbCom decision. I'm afraid this suggests that you and/or your specialization are not notable. I really don't know whether that's the case. — Arthur Rubin | (talk) 23:11, 17 June 2007 (UTC)

Actually, I have published in many areas (see a list of some of my major publications below). It would be notable if you did not consider these areas to be significant. It would also be notable if you did not consider some of my distinguished colleagues to be notable just because they were my students ;-)

Of course there is a large community of distinguished researchers who have the qualifications that I listed as evidently lacking in Ruud Koot and Allan McInnes that are not my students including Gerry Allwein, Jeremy Avigad, Geof Bowker, Jean Pierre Briot, Randy Bryant, Cristiano Castelfranchi, Bill Dally, Mike Dunn, Ed Durfee, Sol Feferman, Jacques Ferber, Rich Fikes, Jeremy Forth, Harvey Friedman, Les Gasser, Mike Genesereth, Mehmet Göker, Pat Hayes, Tony Hoare, Mike Huhns, Toru Ishida, Bill Jarrold, Nick Jennings, Alan Kay, Ben Kuipers, Bob Kowalski, Pat Langley, Victor Lessor, Vladimir Lifschitz, John McCarthy, Robin Milner, Marvin Minsky, Peter Neumann, Pablo Noriega, Sascha Ossowski, Ray Perrault, Graham Priest, Edwina Rissland, John Reynolds, Dan Shapiro, Jaime Sichman, Wilfried Sieg, Leigh Star, Mark Stickel, Chuck Seitz, Katia Sycara, Pete Szolovits, Gerry Sussman, Dana Scott, Munindar Singh, Richard Waldinger, Jeannette Wing, Michael Wooldridge, and others too numerous to list.--Prof. Hewitt 01:31, 18 June 2007 (UTC)

I don't recall claiming any special knowledge in the area of "Carl Hewitt's research".

By the norms of the scientific community, by stepping in and making the changes you made, you are implicitly claiming certain qualifications analogously to intervening by speaking up at a scientific meeting.--Prof. Hewitt 08:03, 18 June 2007 (UTC)

Not at all. What I've implicitly claimed (to the extent that I've claimed anything) is some familiarity with Wikipedia's policies and guidelines. I've deleted some material that a number of editors (see here) seemed to think was inappropriate, and requested that we discuss the material in question on this talk page before (or if) it gets added back into the article.

You have taken the following actions:

Distinguished scientists that Allan McInnes removed from the list of students of Prof. Hewitt

Allen McInnes has removed the names of distinguished scientists from the list of students in the article on Carl Hewitt including Dr. Russell Atkinson, Dr. Gerald Barber, Dr. Peter Bishop, Professor William Clinger, Dr. Peter de Jong, Dr. Irene Greif, Dr. Kenneth Kahn, and Professor Akinori Yonezawa.--Prof. Hewitt 19:32, 19 June 2007 (UTC)

Great! Does this mean that we can finally discuss content instead of arguing around the issue? Please, let's do so.

The Infobox field in question is labeled as listing "notable" students. As my original edit summary stated, I removed from then list those students who apparently are not notable enough to have so far had a Wikipedia article written about them. This is, I confess, a crude standard. However, the list was substantially longer than that found in articles about some other academics (such as Seymour Papert), and while roughly same length as the list for someone like Marvin Minsky the redlinks looked bad, IMHO, since they called into question the veracity of the list (some might argue that it was being artificially inflated - especially given what I just said about the length compared to that of other important academics).

That said, I'll happily concede that it's entirely possible for someone to be notable, and yet not have had Wikipedia article written about them yet. Do any of the (former) students you have listed meet the Wikipedia criteria for academic notability? If so, which students, and which criteria do they meet? (Will Clinger is the one that most immediately leaps to mind, given his extensive work on the R^nRS Scheme specs, which I believe arguably constitutes "a significant and well-known academic work" within the meaning of WP's notability criteria; Irene Greif also seems a likely candidate, although it seems that if there was a WP article about her it was deleted in May for not meeting the notability criteria). Despite the redlinks, I'd certainly be amenable to adding those students back to the infobox, particularly if we can find some way to footnote those names which are redlinks with some kind of reference which supports their notability (relative to Wikipedia's notability criteria). --Allan McInnes (talk) 01:24, 20 June 2007 (UTC)

There is an inconsistency between the source text of the infobox and the display text. The source text simply says "doctoral students" whereas the display text says "notable students". I would propose changing the display text to distinguished students since this is a more standard scientific category. There is no doubt that Dr. Russell Atkinson, Dr. Gerald Barber, Dr. Peter Bishop, Professor William Clinger, Dr. Peter de Jong, Dr. Irene Greif, Dr. Kenneth Kahn, and Professor Akinori Yonezawa are all distinguished scientists. Each of them produced a doctoral thesis at MIT (no mean feat in itself!) and subsequently did exemplary work. However, it make take a very long time for the Wikipedia to catch up to this fact.--Prof. Hewitt 02:04, 20 June 2007 (UTC)

I don't doubt that the students you have listed are distinguished, and have done some great research. I also have the highest respect for MIT and its standards. However, the issue isn't about respect, or whether your former students are distinguished. The issue is whether or not they are considered notable within Wikipedia guidelines. The infobox is a Wikipedia-wide template. If you wish to change the template, or the criteria for the inclusion of students within the template (which I note specifically states that "any students that aren't notable enough to have their own wikipage should be deleted"), then I suggest you take it up at Template talk:Infobox Scientist. Alternatively, you might look into getting the academic notability guidelines changed to incorporate the "more standard" scientific category of "distinguished students". --Allan McInnes (talk) 02:19, 20 June 2007 (UTC)

Since the infobox is internally inconsistent, I suggest removing the whole infobox as inaccurate. The distinguished scientists who obtained their doctorate under my supervision could be mentioned in the article. Also the article could mention that I held the IBM Japan Chair at Keio. The other information in the infobox is already mentioned in the article.--Prof. Hewitt 02:34, 20 June 2007 (UTC)

Works for me. --Allan McInnes (talk) 03:42, 20 June 2007 (UTC)

Material that Allan McInnes removed from the article on Prof. Hewitt

Allan McInnes has removed the following material from the article on Carl Hewitt:--Prof. Hewitt 19:32, 19 June 2007 (UTC)

Using program schemata in collaboration with Mike Paterson, Hewitt proved that recursion is more powerful than iteration and that parallelism is more powerful than recursion. In collaboration with Henry Baker, he published physical laws for computation which they then used to derive the continuity criterion for computable functions of Dana Scott. Using participatory semantics, he proved that coroutines are more powerful than recursion and that Concurrency is more powerful than parallel coroutines.The Ultraconcurrency Revolution in Hardware and Software

Together with Bill Kornfeld, he developed the Scientific Community Metaphor. He has also made contributions in the areas of garbage collection, programming language design and implementation, open systems, Organizational Computing, logic programming, and denotational semantics of concurrency, and paraconsistent logic Hewitt (2007) with his students and colleagues.Using program schemata in collaboration with Mike Paterson, Hewitt proved that recursion is more powerful than iteration and that parallelism is more powerful than recursion. In collaboration with Henry Baker, he published physical laws for computation which they then used to derive the continuity criterion for computable functions of Dana Scott. Using participatory semantics, he proved that coroutines are more powerful than recursion and that Concurrency is more powerful than parallel coroutines.The Ultraconcurrency Revolution in Hardware and Software

Subsequently Hewitt has worked to integrate sociology, anthropology, organization science, the philosophy of science, and services science into information science.

He has an interest in massive concurrency. The Ultraconcurrency Revolution in Hardware and Software

I realize that you might believe that you have good excuses for taking the above actions. However many of my colleagues hold high standards and I am afraid that they may judge your actions extremely harshly.--Prof. Hewitt 19:32, 19 June 2007 (UTC)

Great! Another opportunity to actually discuss content. Ok, the objections that I saw raised in the AfD debate essentially boiled down to (I think) four things:

1 Poor English in places (which I hope we can fix through a rewrite).

2 Inappropriate external links - I believe that this is primarily a reference to the inclusion of links to your blog in several places within the article, which is generally frowned upon. It would be better if we could eliminate the blog links completely (although you appear to be trying to use them as references, in contradiction to WP:RS). Failing that, a single listing in the external links section might get by the WP:EL guidelines (but we'd still need to replace the citations of the blog with something else).

Future and Recent Hewitt seminars is not a blog. It republishes seminar announcements that have been published at research institution websites including Berkeley, MIT, Stanford, SRI, UT Austin, etc. Unfortunately, the original web pages tend to disappear after a while and so that have to be republished elsewhere so that they can be referenced.--Prof. Hewitt 04:05, 20 June 2007 (UTC)

It would probably be safer (and less likely to generate objections) to use Wayback Machine links for that kind of thing, particularly anything that you want to use as a citation. Probably safe enough to keep the link in the External links section though (although I suspect some people might complain about it being advertising, since it claims to discuss "future" seminars as well - I'll leave you to defend that particular complaint if it comes up). --Allan McInnes (talk) 04:27, 20 June 2007 (UTC)

Unfortunately, I have not found the Wayback Machine to be reliable for this sort of thing. The advertising thing is a fine point. However, the blog only republishes notices that have been published on research institutions websites so it is not an original source.--Prof. Hewitt 04:41, 20 June 2007 (UTC)

Might I suggest then that you (a) change the name to just "Recent Hewitt Seminars", so that it seems less like you're advertising upcoming events, and (b) if you wish to use the abstracts in question as references then include URLs for the original notices so that (even if they eventually become invalid) there's some record of the location from which notices were republished, and others can have opportunity to use Wayback or some other archival service to look for the original publication if they so desire. --Allan McInnes (talk) 04:59, 20 June 2007 (UTC)

3 "Non-notable information". I'm guessing that's largely a reference to the fact that several quite specific research results are called out, despite the fact that there's no indication that those results are actually noteworthy enough to warrant being called out in that way (Planner and the Actor model are widely mentioned, even in articles that are not strictly technical - these other results are not). Perhaps we could consider toning those sections of the article down a little, and simply describe the major areas in which you've worked instead of detailing specific results (alternatively, if you can point me to references regarding some of those other results that parallel that references I've found on Planner and the Actor model, then maybe we could justify keeping those specific results).

4 Self-authorship in violation of WP:AUTO and WP:COI. The things I left in the current version of the article were parts that I had either written myself, or substantially edited, which I think overcomes the objections about self-authoring. The stuff I removed (which you have pasted in above) was still, I think, predominantly your writing. Obviously, the only way we can overcome the objections about self-authorship is if someone other than you writes the article. At this point, I appear to be the only person with even a passing interest in doing that.

Wikipedia:Biographies of living persons says "Wikipedia is a top-ten website, and with such prominence comes a measure of responsibility...The Foundation and Jimbo Wales get well-founded complaints about biographical content on living people every day — people justifiably upset at inaccurate or distorted articles. The successful resolution of such complaints is a touchy matter" My primary concern is correcting the accuracy of the article.--Prof. Hewitt 04:23, 20 June 2007 (UTC)

I appreciate your desire for accuracy. However, from the same policy we find: While Wikipedia discourages people from writing new articles about themselves or expanding existing ones significantly, subjects of articles remain welcome to remove unsourced or poorly sourced material. (emph. mine)

Since we're on to quoting policies and guidelines:

• From WP:AUTO:

• Writing autobiographies is highly discouraged.
• It is difficult to write neutrally and objectively about oneself. You should let others do the writing.
• Wikipedia does not wish to have an inaccurate article about you. We want it to be accurate, fair, balanced and neutral. Our goal is to accurately reproduce the opinions of others, which should be sourced and cited. You can help by pointing us to sources which can enable a more balanced view to be presented. (emph. mine)

• From WP:COI:

• Conflict of interest often presents itself in the form of self-promotion, including advertising links, personal website links...'
• Be careful about excessive citation of your own work, to avoid the appearance of self-promotion. When in doubt, discuss on the talk page whether your citation is appropriate, and defer to the community's opinion.

--Allan McInnes (talk) 04:53, 20 June 2007 (UTC)

--Allan McInnes (talk) 02:05, 20 June 2007 (UTC)

Speaking of Wikipedia guidelines, please try to assume good faith

I am prepared to believe that you took the actions above in good faith. However, I am afraid that many of my colleagues may question your judgment.--Prof. Hewitt 19:32, 19 June 2007 (UTC)

That is, of course, their prerogative. --Allan McInnes (talk) 02:05, 20 June 2007 (UTC)

I have put a substantial amount of effort into converting references in this article to inline citations, finding references which actually establish notability (something that helped to prevent the article from being deleted in the current AfD), and otherwise tried to improve the article. I am still trying to do so. --Allan McInnes (talk) 07:22, 19 June 2007 (UTC)

The strong norms in the scientific community against censorship may lead many of my colleagues to question your judgment in taking the actions to remove respected scientists from my list of students and to censor the article in order "to improve the article".--Prof. Hewitt 01:39, 20 June 2007 (UTC)

The edit I'm assuming that you are complaining about simply removed a chunk of material which appeared (to me) to be a report of various research results with no effort made to establish the notability of the results (most or all references were to the publication on the work itself, rather than anything that indicates that the work in question was actually notable).

There is conflict between the norms of the scientific community and certain current practices on the Wikipedia. The scientific community has long established practices for addressing issues of significance and accuracy. Those who don't have the qualifications that are listed at the beginning of this this section basically have no basis for determining current significance. Those who do have the qualifications have vigorous discussions and debates about these matters.

I am not aware of any norms in the "scientific community" for writing biographies of academics. If you know of some, I'd be interested in seeing them. Alternatively, if you can provide a few links to biographies of academics that you think illustrate those norms, that might be helpful. --Allan McInnes (talk) 07:22, 19 June 2007 (UTC)

However, there are strong norms against censorship. It is not completely obvious how we can help you since you evidently currently do not have the qualifications to judge the significance of current work. (Hopefully your will do an excellent dissertation and become more qualified!) One suggestion that I would make is that if a paper is published in a respectable forum, then it should be able to be reported in the Wikipedia. This holds especially for recent publications because one of the claimed advantages of the Wikipedia is that it is more accurate than older encyclopedia models because it is more current. Consequently, the fact of being out of date can be a valid criticism of a Wikipedia article.

I sincerely doubt that the completion of my dissertation has any impact on my "qualifications" to edit this article, except on paper.

Hopefully you will learn a great deal from your experiences in getting a doctorate that will improve your qualifications!--Prof. Hewitt 01:08, 20 June 2007 (UTC)

My knowledge prior to writing the last sentence of the dissertation is no different to my knowledge after writing that last sentence.

I consulted with a respected colleague on this discussion. She suggested that you show this dialog to your advisor and get his opinion.--Prof. Hewitt 01:08, 20 June 2007 (UTC)

Regarding your suggestion, "reporting" on every paper a given academic has "published in a respectable forum" is likely to produce an article that is lengthy, and a biography that amounts to little more than a bibliography. Since (a) there are other venues for bibliographies, and (b) a bibliography is no substitute for a biography, I'd rather focus on producing articles that are biographies.

You misunderstood me.

1. I suggested that an article on an author be encouraged to have a subarticle on the major publications of that author (when this makes sense). In this way the major publications would not clutter the main article. Of course the subarticle on the major publications would consist of reporting on the biographical, historical and scientific aspects of the major publications. So the subarticle would not just consist of the list of major publications.--Prof. Hewitt 19:32, 19 June 2007 (UTC)
2. I suggested that it is the job of the Wikipedia to report on significant new scientific papers published in respectable forums. E.g. the subarticle on publications should presumptively include the new publications of an author with a biography in the Wikipedia.--Prof. Hewitt 19:32, 19 June 2007 (UTC)

I have no interest in debating this issue any further, for the reasons I have already stated. --Allan McInnes (talk) 02:05, 20 June 2007 (UTC)

In that vein, it would be helpful if you could provide pointers to any biographical material that has been written about you. I've searched myself, but have had difficulty laying my hands on anything substantial (what I've found so far I've already added to the article as references). I'm assuming that you are in a much better position than I to identify such information. --Allan McInnes (talk) 07:22, 19 June 2007 (UTC)

Quite often a student someplace has said "I haven't heard of this new thing that has just been published and therefore it can't possible be significant" ;-) or said "Show me proof that this new thing that has just been published is significant" ;-) ;-) Unless someone is an up-to-date well qualified expert in exactly the subject of the new publication, they can't possibly have a basis for judgment. Even then they can be wrong!

So I think that the Wikipedia is better off just reporting on new publications as they occur in respectable forums rather than attempting to judge a priori the significance of the publications and suppressing mention of those thought insignificant by people with dubious qualifications. I.e., the task is to report on the new publications with explanations of what they say including any claims to significance that may be contained in the publications themselves. Going further raises the risk of original research creeping into the Wikipedia.--Prof. Hewitt 08:03, 18 June 2007 (UTC)

As I have mentioned previously on this talk page, I don't think that reporting on every publication, in the fashion you suggest, is feasible or in the scope of Wikipedia.

Of course it's feasible to have subarticles on the major publications of significant scientific authors! The Wikipedia is constantly evolving. As Jimbo likes to say: "We are making this up as we go along!" Also the Wikipedia encourages boldness ;-) So it is perfectly feasible to do a couple of subarticles as an experiment and see how it works out.--Prof. Hewitt 19:32, 19 June 2007 (UTC)

Wikipedia does not "report" on everything. Other venues are better outlets for such out-of-scope material (such as Wikinews for current events, or the academic wiki that I previously suggested that you consider starting). If you honestly feel that the things you are suggesting are in-scope for Wikipedia, then please take these proposals to the Village pump (as I have also previously suggested) and see if you can get them turned into a content guideline of some kind. Debating what amounts to a Wikipedia policy issue here will get us nowhere. --Allan McInnes (talk) 07:22, 19 June 2007 (UTC)

My removal of material was carried out in response to the opinions expressed during the recent AfD debate regarding this article. As I made clear on my edit summary, I'm happy to discuss the material in question on this page (perhaps we could invite some of the other editors from the AfD debate to participate). But, given the opinions expressed during the AfD debate, I don't think it's appropriate to simply add back the material that I removed without discussing it here.

I am afraid that many in the scientific community will consider you responsible for your actions and will hold you accountable.--Prof. Hewitt 08:03, 18 June 2007 (UTC)

Certainly I am responsible for my actions. I specifically elected to use my real name as my login, rather than editing anonymously or using a pseudonym, precisely because I choose to take responsibility for my edits. I am not sure exactly what you mean by the phrase "hold you accountable", but if the "scientific community" wants to hold me accountable for trying to produce a quality encyclopaedia they are welcome to do so. --Allan McInnes (talk) 07:22, 19 June 2007 (UTC)

See my comments above on the strong norms in the scientific community against censorship.--Prof. Hewitt 19:32, 19 June 2007 (UTC)

I have previously asked you to help identify a set of "selected works" which you consider particularly influential, since I am "obviously unqualified" to judge the notability of the listed works. But you have so far been unhelpful in this regard.

As we discussed before in this article, it is not clear what to use as the selection criteria! (See below.)--Prof. Hewitt 08:03, 18 June 2007 (UTC)

Yet somehow you've managed to come up with a list of "major publications". So there must be some selection criteria at work. In any event, if coming up with selection criteria is too hard, then perhaps the right answer is to not include a "selected works" or "list of publications" section at all (many WP academic biographies do not). Instead, we can simply link to external bibliographic information. --Allan McInnes (talk) 07:22, 19 June 2007 (UTC)

There are well established norms in the scientific community for "major publications". Criteria for "selected publications" are quite a different matter. The issue of "selection" tends to come up in compilations reprinting previous publications.--Prof. Hewitt 19:32, 19 June 2007 (UTC)

The list you have provided below is too lengthy to included in the article in its entirety.

The list given below at least has the virtue of being accurate, i.e. it is a list of some of my major publications. (I agree that the list of all of my publications is too long and should not be included.) Also it is about a page in length. So it should either appear at the end of an article or (better) it should appear in subarticle of the main article. As we discussed before, having the major publications of an author appear in a subarticle would have the advantage that other Wikipedia editors could then report on the overall structure of the publications as well as on individual publications.--Prof. Hewitt 08:03, 18 June 2007 (UTC)

Of those Wikipedia bios of academics that include "selected works", the ones I'm aware of are relatively short lists - see, for example Marvin Minsky#Selected works or Seymour Papert#Selected bibliography.

I am afraid that the "selected" approach is fundamentally flawed in that the criteria for selection is unclear and therefore unreliable and subject to fruitless debate. E.g., the current "selected works" in the Minsky article is missing his famous frames paper and the current "selected biography" in the Papert article is missing the famous 1971 report that he co-authored with Minsky on progress in Artificial Intelligence. So what was the criteria for selection?

I agree that selection criteria are problematic. Yet Wikipedia style guidelines mandate some kind of inclusion criteria for lists. Perhaps list of publication should not be included at all. See above as well. --Allan McInnes (talk) 07:22, 19 June 2007 (UTC)

For encyclopedic accuracy, we need a list of major publications of each author. In cases of authors with many publications over a long period (e.g. John von Neumann, John McCarthy, etc.) it may be desirable to divide the publications into categories.--Prof. Hewitt 08:03, 18 June 2007 (UTC)

I disagree with your assertion that Wikipedia needs to list the major publications of each author, for two reasons:

1. As you have already pointed out, selection criteria are problematic. How does one judge "major"?
2. I do not think that such lists are necessarily "encyclopaedic" - encyclopaedias are supposed to summarize other material, rather than to collect that material. In particular, Wikipedia is not an indiscriminate collection of information.

Furthermore, as I've already pointed out several times, what you are suggesting amounts to a Wikipedia-level decision (policy, guideline, or something similar), which is better discussed in other places than the talk page of an individual article.

--Allan McInnes (talk) 08:20, 19 June 2007 (UTC)

Lastly, I would like to point out that, while I (to paraphrase you) "evidently lack the qualifications" to judge the notability of your work, I have taken the time to dig up references which support the notability of you and your work (while others have argued that you are not "notable" at all), including references to writings by Robin Milner, Dan Friedman, and Alan Kay (the last of those is no longer in the article).

I agree that it was a contribution to have brought these citations forward. And the ones that you found are not bad ;-) I wonder why the one by Kay was deleted from the article?

It was removed because the material it supported was more relevant to the Actor model article than to this one, so I moved the reference over there. --Allan McInnes (talk) 07:22, 19 June 2007 (UTC)

A weakness of the citation approach is that it can be very idiosyncratic. For example, it's not immediately obvious where to dig up a good citation for highly significant work such as Comparative Schematology, the Scientific Community Metaphor, etc. Also, although many in the community believe that the work on Direct Logic is highly significant, there are no citations because the publications are too recent. More fundamentally, the scientific community does not take such citations as primary evidence of significance. So the Wikipedia should not take such citations in a simplistic way as the basis for judging significance.--Prof. Hewitt 08:03, 18 June 2007 (UTC)

As far as I can tell, I'm the only one that has actually bothered to add such references to the article. If you know of other references along similar lines, then by all means mention them here and I'll see that they are added.

Unfortunately, a list of all of the published citations to my work would number in the thousands. --Prof. Hewitt 08:03, 18 June 2007 (UTC)

Then could you perhaps point me to a few that specifically discuss the importance and impact of your work. Since I (in your words) "Evidently ... Haven't read much of the specialized literature in the areas where I have published", while you presumably have read a lot of the literature, I'm assuming that you're much more likely than me to be aware of the kind of references I'm interested in finding. --Allan McInnes (talk) 07:22, 19 June 2007 (UTC)

Unfortunately, citations in areas in which I publish are typically technical in nature and do not in general discuss the importance and impact of the work of other authors. However you might check out Multi-Agent Systems: An Introduction to Distributed Artificial Intelligence by Professor Jacques Ferber.--Prof. Hewitt 01:14, 20 June 2007 (UTC)

Thank you. That is helpful. --Allan McInnes (talk) 02:05, 20 June 2007 (UTC)
