CALL FOR PARTICIPATION EKAW91: 5TH EUROPEAN KNOWLEDGE ACQUISITION FOR KNOWLEDGE-BASED SYSTEMS WORKSHOP Provisional Dates: May 20-24 1991, Crieff, Scotland OPEN DAY: May 17, London, England It is the objective of EKAW 91 to assemble theoreticians and practitioners of AI who recognize the need for developing methods and systems to assist the process of acquiring and modelling knowledge for knowledge-based systems. To encourage vigorous interaction and exchange of ideas the workshop will be limited to 40 participants. There will be individual presentations and ample time for technical discussions. An attempt will be made to define the state- of- the-art and future research needs. Attendance will be limited to those presenting their work, one author per paper. Papers are invited for consideration in all aspects of knowledge acquisition for knowledge-based systems, including (but not restricted to): o Transfer/modelling of expertise-systems that obtain and model knowledge from experts. o Transfer/modelling of expertise-manual knowledge acquisition methods and techniques. o Apprenticeship, explanation-based, and other learning systems; integration of such systems with other knowledge acquisition techniques. o Issues in cognition psychology and expertise that affect the knowledge acquisition process. o Extracting and modelling of knowledge from text. o Integration of knowledge acquisition techniques within a single system; integration of knowledge acquisition systems with other systems (hypermedia, database management systems, simulators, spreadsheets...). o Knowledge acquisition methodology and training. o Validation of knowledge acquisition techniques; the role of knowledge acquisition techniques in validating knowledge-based systems. o Methods for capturing design knowledge and requirements. o Theoretical frameworks for knowledge acquisition. o Philosophical issues concerning knowledge and technology. Five copies of an extended abstract (from 4 to 8 pages) or a full-length paper (up to 20 pages) should be sent to Duncan Smeed before February 22nd 1991 Acceptance notices will be mailed by April 5th. Camera-ready copies should be returned before April 26th 1991, so that they may be bound together for distribution at the workshop. Ideal abstracts and papers will make pragmatic or theoretical contributions supported by a computer implementation, and explain them clearly in the context of existing knowledge acquisition literature. Variations will be considered if they make a clear contribution to the field (for example, comparative analyses, major implementations or extensions, or other analyses of existing techniques). Project SISYPHUS The objective of the project is to compare different methods and techniques of knowledge acquisition. Three test bed tasks domains have been chosen.

It was decided at EKAW90 to choose three or four task domains that introduce considerable scope for knowledge acquisition. These task domains would then provide a test bed for comparison of techniques. We would like to propose that researchers and practitioners (preferably those belonging to a team or group) who are currently involved in knowledge elicitation and acquisition analyze one sample problem and make their analysis of this problem widely available. The results of the analysis of each group (each using its own approach) will be published in the proceedings of EKAW91 and will be discussed during the workshop at special set sessions. Research groups wishing to participate in this venture are asked to submit a very short description (1 - 2 pages) of their work and their experience. By 1st December, 1990 we shall also require from each potential participating group a short description of their proposed approach together with some indication of the type and extent of solution they may anticipate. In the event that more groups would like to participate, we shall select 3 or 4 groups for each test bed application. By 15th January selected groups will be notified and sent the material that describes the sample problem. By 1st March, 1991 the selected groups will each be asked to return a ten page paper describing their analysis, their representation and some additional comments. All the papers will be included in the proceedings of EKAW91. Interested researchers and practitioners can obtain project details directly from the respective project addresses below. Subsequent submissions should be sent to the individual contact and also to the project coordinator:- Tom Addis, Project Sisyphus Coordinator, Knowledge Systems Group, Computer Science Department, University of Reading, Whiteknights, Reading, RG6 2AX.

Text Analysis Text-based material is a common source of information for knowledge engineers when building knowledge-based systems. Text may be generated from interviews, verbatim protocols and/or textbooks and scientific or technical papers. Identifying meaningful information and then developing useful knowledge structures from text is the goal of text analysis for knowledge-based development. This call for submissions is directed to those researchers and practitioners who have developed methods, techniques or tools for text analysis. Our goal is to identify and select representative approaches to text analysis and then to offer the same textual material for analysis. The results of the analysis will be published in the proceedings of EKAW91 and will be discussed at the conference. The submission should contain brief but clear statements about: 1. the underlying assumptions of the approach 2. the method for parsing text passages 3. the method(s) and underlying assumptions for analysis of the parsed text 4. the knowledge representation formalism resulting from the analysis 5. potential uses for the method to knowledge engineers Contact: Brian Woodward Knowledge Science Institute Department of Computer Science University of Calgary 2500 University Dr. NW Calgary, Alberta, CANADA T2N 1N4 e-mail: woodward@cpsc.ucalgary.ca Project 2. Models of Problem Solving Many research groups tackle the problem of explicit modelling of problem- solving (see Karbach, Linster & Voss: "Models of Problem-Solving: One Label - One Idea" in Proceedings of EKAW90). They all use different examples to illustrate their work. We want to encourage the members of the community to illustrate their approaches using one test bed example selected from a set of common examples that the organizers of Project SISYPHUS will provide for the participants by 1st November. The problem to be modelled will be a realistic synthesis type problem. We are mainly interested in the explicit modelling of problem solving methods. There is no implication that the results must be or directly result in an operational knowledge base. Mediating representations or specifications that are not directly executable will be welcome. The descriptions of the models will make the approaches comparable and this comparison will hopefully help answer questions such as: 1. How do the building blocks of each of the approaches correspond? 2. Which problem-solving steps does an approach use and are there common steps amongst the different approaches? 3. What grain size is there? 4. Which part of the knowledge is generic to all task domains? 5. What is task dependent in the approaches? 6. What is the role of the knowledge engineer? The descriptions of the models will be the basis of the discussion at EKAW91 and these discussions will hopefully result in a common terminology as a first step towards a theory of problem-solving in Knowledge-based Systems.

Modelling Meta-Data In statistical processing, information about the data needs to be taken into account to be able to analyze the data correctly. This concept of information about data is referred to as meta-data. The purpose of the project Modelling Meta- Data is to document the use of meta-data --based on empirical evidence-- and to develop a formal language for the description of meta-data. Based on these results a system will be developed to support the analysis of statistical data. The project has to start with gathering information about meta-data in an actual setting. The results of the project have to be useful for a particular target population, i.e. the producers and users of statistical data, such as national statistical institutes. Consequently, experts at these institutes are the prime sources of knowledge. The central question to be answered is, which information about data they use during statistical processing. For the time being, the investigation is restricted to statistical processing in a single domain, i.e. family budget research. If successful, investigation and support in other domains will be added. Institutes in several countries are involved in this project. The knowledge acquisition will be done by one of these institutes. This means that in general the knowledge engineer will visit the experts, and not the other way around. So, if anybody proposes to use automated KA tools, the necessary hardware should be portable or rather common. The central question research groups are supposed to tackle is: what kind of knowledge acquisition is useful in this situation, how should one proceed, which tools could or should be used? Two kind of papers are possible. On the one hand, papers giving an answer to these questions, but going no further. And on the other hand, papers in which the results of an actual KA process are described. In this last case, it seems not strictly necessary to focus on family budget research. If an expert is at hand, who happens to be specialized in a different field of statistical processing, e.g. time-dependent data or government expenditure, his or her knowledge could just as well serve as an example of the KA procedure.

His greatest crime was to capture the Goddess of Death herself and keep her prisoner. Pluto sent the God of War to return Death to her rightful place. He attempted to cheat death a second time by obtaining permission from Pluto to return to Earth in order to chastise his wife for putting obedience above love. This time Mercury was sent to drag him back to the Underworld. His punishment for all his crimes against the Gods was to be condemned forever to push a large rock up a hill only for the rock, at the top, to roll back down into the valley and for him to start again. This was thought by the Gods to be the ultimate punishment; to suffer the despair that must ensue by being enslaved to carry out such a pointless task. However, Sisyphus cheated the Gods once more by developing his capacity to push the rock up the hill. He formed a pride and a pleasure in the exercise of his skill. The interlude while he walks down the hill each time to start again also has a joy that is achieved through the contrast in his efforts; he has time to reflect on how to improve his next assault on the hill.
