The aim of the BEES project is to improve the communication and cooperation between users and knowledge based systems. It resulted from the realization that current expert systems (ES) provide very limited explanations to their users (the traditional "how" and "why" questions). In many cases their acceptability, marketability and usability would be greatly improved if such systems could interact in a more cooperative way to solve problems through the combined expertise of user and ES. Development of more cooperative ESs involves investigation of what domain knowledge is needed and how it should be represented so that the ES can answer some of the many different sorts of questions which users wish to ask. Additionally, the ES must hold information about the user, so that it can communicate effectively and efficiently, in terms which the user understands. We are currently working on the following areas: representing the variety of knowledge required, natural language processing, generating textual responses, integrating graphical and textual explanations, behavioural studies of advisors and users, developing a taxonomy of explanations. 11:00am September 25 BIC Conference Room Unisys Paoli Research Center Route 252 and Central Ave. Paoli PA 19311 -- non-Unisys visitors who are interested in attending should -- -- send email to finin@prc.unisys.com or call 215-648-7446 -- ------------------------------ To: nl-kr@cs.rpi.edu Date: Mon, 11 Sep 89 19:14:53 -0400 >From: kumard@cs.Buffalo.EDU (Deepak Kumar) Subject: Workshop Announcement & Call for papers CALL FOR PAPERS FIRST ANNUAL SNePS WORKSHOP Co-Sponsored by the SNePS Research Group and the SUNY at Buffalo Center for Cognitive Science November 13, 1989 280 Park Hall North Campus SUNY at Buffalo SNePS, in its various incarnations, is being actively used and developed at various AI research labs around the world. The aim of this workshop is to try to get together researchers who are (have been, or are considering) using SNePS as a research tool for AI modeling as well as those who are (have been, or are considering) evaluating SNePS as an AI research environment. The theme of this workshop is to present a survey of current and on-going research and developments at various research sites. Attendance at the workshop will be kept small (by invitation only) to allow for maximum possible interaction among participants. The workshop will be semi-formal and held on the campus of SUNY at Buffalo (where the SNePS headquarters are located). All papers presented will be edited and compiled into Proceedings which will be published as a Department of Computer Science, SUNY at Buffalo Technical Report. To be invited to the workshop, you have to do one of the following (preferably by e-mail): 1. Submit a one page abstract of a paper to be considered for presentation. 2. Submit a short write-up of your current research and how it does/might relate to the SNePS family of projects. We will also schedule a time slot for live demonstrations of systems. Those interested in giving demonstrations should submit a small description outlining the nature of the demonstration along with hardware/software/time requirements. DEADLINES Abstracts/Research Summaries due on Friday, October 6, 1989. Notification of acceptance/participation by October 13, 1989. Final papers due on Tuesday, October 31, 1989.

Text analysis methods based largely on statistical methods have, however, been used successfully in information retrieval and related areas for many years. The main text analysis methods usable with general purpose texts are briefly reviewed and applications are described in such areas as document retrieval, book indexing, linking of related text excerpts, subject area organization, and so on. Evaluation output is shown wherever possible to demonstrate the effectiveness of the proposed methodologies. ------------------------------ To: nl-kr@cs.rpi.edu >From: munnari!ait.trl.OZ.AU!jacob@uunet.UU.NET (Jacob Cybulski) Newsgroups: comp.ai.digest,comp.ai.nlang-know-rep,aus.ai Subject: Re: Connectionist Approaches to NLU Date: 14 Sep 89 00:20:31 GMT Last week I sent a request for references on connectionist approaches to natural language processing.

This is true because current knowledge representation languages do not provide well suited representational means neither to describe sets, subsets, and elements nor to deal with the respective relations or use them in specially tailored inference systems. On the other side, there exists (at least) one linguistic theory about plurality in natural language, the General Quantifier Theory (GQT). What we want to present in this paper is how we adopted this theory into the already existing framework of the XTRA system. Our goal therefor is to develop a well-grounded knowledge representation formalism able to represent sets as well as to deal with them and combine this representation formalism with a well-defined linguistic theory. The knowledge representation language SB-ONE+ integrates sets into the KL-ONE like KR language SB-ONE. It realizes this by means of regarding sets as epistemological primitives, thus allowing for both an implementation of set-relevant properties (like reasoning about subset-of and element-of relationships) in the system as well as a description of sets as elements inside the TBox if relevant for the domain under consideration. Taking SB-ONE+ as representational basis, we show how some inte- resting results from GQT are implemented in the XTRA system. 11:00am September 20 BIC Conference Room Unisys Paoli Research Center Route 252 and Central Ave. Paoli PA 19311 -- non-Unisys visitors who are interested in attending should -- -- send email to finin@prc.unisys.com or call 215-648-7446 -- ------------------------------ To: nl-kr@cs.rpi.edu >From: E3T@PSUVM.PSU.EDU Newsgroups: comp.ai.nlang-know-rep Subject: CALL FOR PAPERS Mathematical Programming and Expert Systems...
