From: AIList Moderator Kenneth Laws <AIList-REQUEST@SRI-AI.ARPA> AIList Digest Tuesday, 19 Mar 1985 Volume 3 : Issue 37 Today's Topics: Expert Systems - RULEMASTER Language, Humor - ))) & Sesame Street FA, Policy - Censorship & Rape, Seminars - Social Effects of Computing (SU) & Expert Systems in China & TUILI (SU) ---------------------------------------------------------------------- Date: 18 Mar 85 10:42:55 EST From: Mary.Lou.Maher@CMU-RI-CIVE Subject: RULEMASTER Language Has anyone heard of the RULEMASTER language for building expert systems? It is an inductive system; i.e it learns rules from examples, can interface with lisp, pascal, c, or fortran, and can access databases. It was developed under the direction of Donald Michie and sold by Radian Corp. I am considering going to take their tutorial course and would like to know if anyone has heard of or used this language. ------------------------------ Date: Sat 16 Mar 85 04:47:58-CST From: Werner Uhrig <CMP.WERNER@UTEXAS-20.ARPA> Subject: RE: Found: right parens RE: Sorry, I have not seen your asterisks, but please! Does anyone know where the daily bit buckets are stored? I lost some data Thusday night by doing one too many left shift on a program I was writing on SCORE and I was wondering whether I might be in some way able to recover the bit strings. Any help would be greatly appreciated. Formerly, the NSA sent all dropped bits to the shredder, but these days they are transported nightly via Federal Express to MCC where they are trying to solve the problems that escaped the rest of y'all. Earlier this week a comment was overheard between two members of a visiting Russian delegation to Texas' high-tech city: "Dammit, comrade, they look all alike." I no longer wonder what they were refering to. [Hey, if you think this is lousy humour, watch David Letterman sometimes. I figure Johnny Carson supports him to justify his own whopper of a salary] ------------------------------ Date: 15 Mar 85 19:01:21 EST From: Carl.Ebeling@CMU-CS-UNH Subject: Sesame Street FA [Forwarded from the CMU bboard by Laws@SRI-AI.] I was watching Sesame Street today (getting the kid started early) and it appears that they are teaching some beginning theory. They had a box that accepted only the letter 'A'. Next week they're going to cover regular expressions and the Pumping Lemma. ------------------------------ Date: Friday, 15-Mar-85 11:05:43-GMT From: DIANA HPS (on ERCC DEC-10) <"[140,153]%edxa"@ucl-cs.arpa> Subject: Censoring jokes about rape [Though rape is a barbaric act, censorship is a far worse crime for it affects so many more.......] I'm not going to answer your first point because, like you, I have never been the victim of rape and hence cannot compare the effects of rape with those of censorship. But I will just say that FEAR of rape has profoundly affected the lives of at least as many people as censorship; indeed, it even acts as a kind of censorship - a censorship of behaviour, of being afraid to say certain things, go to certain places, enter into certain kinds of relationship, even to be out of doors at certain times of the day. And to imply i) that rape is a normal part of human(male) behaviour, or ii) that the victim enjoyed it (the Poly Nomial joke does both) is to encourage an acceptance of attitudes that lead both to rape and to that fear. [There is a fundamental difference between an act and writing about an act. If jokes about a subject are banned, how long is it before satire about the same subject is banned? Then there is only a small step fiction is banned. Next comes fact, research...] There is actually a very big leap between banning jokes which casually make assumptions that are damaging to a group of people, and banning satire which questions people's assumptions. For example, you would probably not want to encourage the circulation of a joke that took it for granted that the victims of shooting, mugging or theft enjoyed the experience? In a sense, such jokes have already been censored - no-one even writes or tells them! [..Any reasonable definition of rape should include the fact that the raper and rapee are human or at least members of the animal kingdom. I find it hard to be offended when polynomials are raped, however.......] I'm very surprised that David enjoyed the joke, since he seems to have missed its main point. The point of the joke is that the language used to describe mathematical functions can be neatly turned into a description of a piece of human behaviour. It certainly would have been very funny, if it had not required the acceptance of the two appalling assumptions regarding rape that I noted above. Apropos, I should like to know how AIlist readers would have reacted if the joke had referred to 'Paul E Nomial', the 'epitome of masculine qualities', instead of a clearly female character? Would the joke still be funny? Would it still be less offensive than censorship? Diana Bental University of Edinburgh mail: bental%edxa@ucl-cs ------------------------------ Date: Fri 15 Mar 85 13:30:09-PST From: Ken Laws <Laws@SRI-AI.ARPA> Subject: Reply to Diana Bental This discussion of morality on the network should really be conducted on Human-Nets, but I'll permit it to continue on AIList for awhile. (I.e., I can't resist putting in my two-cents worth.) Diana Bental claims that the Impure Mathematics story depicts Poly Nomial as enjoying being raped. I have reread the story and can find no support for this view (aside from a very cryptic remark about having "satisfied her hypothesis"). The entire tone of the story is just the opposite. She also claims that the humor in this piece is in its use of mathematical terms to describe human behavior. I think it equally supportable that the humor is in attributing human emotions to mathematical entities, as David Wilkins said. No doubt both viewpoints contribute to the mental gymnastics that we call humor. As for the offensiveness of this or any other text, I believe that people regard the public distribution of material offensive when 1) the depicted behavior is threatening to them or to their society, and 2) the material is likely to promote such behavior. (There is also a second category of offensive material, namely anything that one finds personally disgusting or frightening. In this case, however, we seldom object to others having access to the material unless it is forced upon them. My wife, for instance, used to have a very strong fear of snakes and worms, but she never felt that such subjects should be banned from the public media.) In support of this view, I submit that subjects we would find very offensive on TV would be perfectly acceptable in a scientific treatise or an X-rated videocassette -- the latter media are less likely to have an effect on social behavior. We perceive less threat in graphic portrayals of war attrocities than in Bugs Bunny hitting Elmer Fudd. Many people have recently found words such as "he" and "chairman" offensive even in technical texts, precisely because they believe that such language does affect our society adversely. I think we all all agree that point one is applicable here: rape is abhorrent. (The question of whether it is "normal human (male) behavior", in the absence of strong social sanctions, could be discussed at great length.) Ms. Bental's comments about the fear of rape being as harmful as censorship are well taken. The applicability of the second point is more doubtful. It may be true that if AIList sanctions such material, the material is more likely to be distributed through other channels having more effect on social behavior. This is far fetched, but is essentially identical to the reasoning behind much of the "sexist language" controversy. Rape is a sufficiently serious social problem that we must consider the possibility of such influences. Let's not get carried away, however. Impure Mathematics >>is<< funny, or at least witty, regardless of whether it has to be banned for social reasons. It does not "require the acceptance" of rape, and might be funny even if it did require a "willing suspension of disbelief". (Cartoons are often based on unbelievable premises.) The story is not intrinsically offensive, any more than is the word "he" or the biblical story of the flood; those of us who enjoyed it are not perverts or misogynists. -- Ken Laws ------------------------------ Date: Sun, 17 Mar 85 15:23 IST From: Henry Nussbacher <VSHANK%WEIZMANN.BITNET@WISCVM.ARPA> Subject: Humor I too cast my vote for humor. Not to repeat what others have said (Issue #34), I have found that computers have been filled with violence and I do not find it intentional. How often do we say 'Let me execute the program...', and realize what we are saying? In VM, when issuing the CMS START command, CMS replies with 'EXECUTION BEGINS...'. A non- computer person looking over your shoulder might be offended if they recently had a person they know executed. The Wylbur operating system uses the command KILL to force a user off the system, and VM uses the command FORCE to do the same. Not very nice language. When a user complains that their terminal is 'dead', they say that their terminal is 'hung'. Not very nice language, indeed. I have often heard users complaining that the system just 'died'. There used to be a regression analysis package that was extended with new functions and was named RAPE (and forced to change its name to RAPFE a few years later). I could go on and on. The point is the author of Poly Nomial didn't intend to glorify rape. No one in their right mind likes rape. But censoring humor is not going to stop rape.

Curtis L. Goodhart's comments (Vol 3 # 33) are very important. AI is a male dominated domain and that should change. The situation is, of course, moving forward, but what we really need is a change of attitude. Gordon Joly gcj%edxa@uk.ac.ucl.cs ------------------------------ Date: Mon, 18 Mar 85 13:45:24 pst From: wfi <@csnet-relay.arpa,@ucsc.CSNET (Wayne F. Iba):wfi@ucsc.CSNET> Subject: rape and censorship [ Though rape is a barbaric act, censorship is a far worse crime for it affects so many more. ] This might have some validity (and I emphasize might) if we were talking about censorship in the context of some government official dictating to various publishers what's to be printed and what's not. However, in the context of the present discussion, we are referring to editorial decisions. Any printed newspaper will print only what it wants with respect to anticipated reader reaction. They generally won't print items which might tend to reduce their readership. For Ken to withold such items in the future is not the same as censorship. Just as you can choose to read a newspaper or not, you can choose to read this newsletter. I am adding my voice to those requesting that such not be printed. Even if I am in the minority, I submit that if for no other reason, we refrain from printing such on the basis that computer science and AI are heavily male dominated to begin with, and that printing stories about rapes in a context which might be amusing, is no way to encourage female involvement. --wayne ------------------------------ Date: Fri 15 Mar 85 12:23:04-PST From: Gio Wiederhold <WIEDERHOLD@SU-SCORE.ARPA> Subject: Seminar - Social Effects of Computing (SU) [Forwarded from the Stanford bboard by Laws@SRI-AI.] CS 300 -- Computer Science Department Colloquium -- Winter 1984-1985. Our final presentation will be on Tuesday, March 19, 1985 at 4:15 in Terman Auditorium Rob Kling Department of Information and Computer Science University of California, Irvine THE SOCIAL DIMENSIONS OF COMPUTERS, COMPUTING, AND COMPUTERIZATION Research on the social impacts of computing indicates few "deterministic" consequences of introducing computer-based systems into social settings such as organizations. Jobs may become more or less skilled; decisions may be "better" or more confused; power may shift to or from central administrators. Much depends upon the kinds of systems introduced, who controls them, and the particular practices and procedures that people develop to use the computer systems and the services that they support. The social consequences of computer use are often very "context sensitive." Moreover, computer-based systems which can be perfectable under static laboratory conditions and when supported by a rich array of resources may be very problematic when introduced into dynamic social settings, settings rife with social conflict, or settings where support resources are limited. This talk will examine some organizing ideas to help understand the context-sensitive character of computerization. One cluster of ideas is embodied in web models and these will be explained in the talk. ------------------------------ Date: Mon 18 Mar 85 12:19:29-PST From: Paula Edmisten <Edmisten@SUMEX-AIM.ARPA> Subject: Seminar - Expert Systems in China & TUILI (SU) [Forwarded from the Stanford SIGLUNCH distribution by Laws@SRI-AI.] SPEAKER: Dr. Ru-qian Lu, Professor and Head of Department of Computer Science, Institute of Mathematics, Academy of Science, Beijing, China ABSTRACT: This will be a combination of two talks: 1. DEVELOPMENT OF EXPERT SYSTEMS IN CHINA (SELF EXPLANATORY) 2. TUILI - A GENERAL PURPOSE TOOL FOR DESCRIBING EXPERT SYSTEMS (ABSTRACT BELOW) DATE: Friday, March 22, 1985 LOCATION: Chemistry Gazebo, between Physical and Organic Chemistry TIME: 12:05 Since the seventies, more and more people are involved in developing expert systems. But most of them are special-purpose systems, containing only knowledge and experiences of a special field, even of a special person (such as an experienced doctor of traditional Chinese Medicine). Despite the advances in the field of knowledge representation, general-purpose tools for describing expert systems are still rare and in the early stage of their development. In many cases, they are only new versions of existing special-purpose tools with minor extensions. Tuili (Tool for Universal Interactive Logical Inference) takes the generality as one of its important design goals. The main mechanism of its knowledge representation are production rules, but other mechanisms can be simulated as well. Here are the main characteristics of Tuili: 1. Not only predicates, but also predicate procedures are allowed in production rules. 2. The parameters of predicates and predicate procedures are pattern elements of different data types. 3. A new principle of semantic pattern matching is proposed. Users are allowed to define their own pattern matching rules. 4. Users can define their own probability functions, attribute functions and their propagation rules during the course of inference. 5. Rule bases and data bases are modular structured. 6. The control structure is represented as production rules, they form the meta-structure, which can be organized hirarhically to form a multi-level control structure. 7. The system provides a rich set of built-in control strategies to be chosen from by users. They can define their own strategies, too. At present, Tuili is being used to write an expert system for brain diseases and one for teaching traditional Chinese Medicine.
