EUROVAV 91 : EUROPEAN WORKSHOP ON THE VALIDATION AND VERIFICATION 
OF KNOWLEDGE BASED SYSTEMS

22-24 July 1991
Jesus College 
Cambridge 
England

Tel: +44-223-66343
Fax: +44-223-322315

Sponsored by Logica in association with the Commission of the European 
Communities and the Department of Trade and Industry

Workshop Objectives

As the number of knowledge-based systems being deployed continues to grow 
there is an increasing need to provide mechanisms and techniques to evaluate 
the extent to which completed systems satisfy their original objectives. This
is important not only to the users of such systems, but also provides
invaluable feedback to developers about the effectiveness of their knowledge-
based systems technology.

Verification and Validation of knowledge-based systems is of key importance
in this process and will be a major contributing factor in the deployment of 
knowledge-based systems in a wide range of application areas. The objective
of this workshop is to bring together researchers who share an interest in the 
validation of knowledge based systems and related fields in order to define
the state-of-the-art and future research needs. 

To encourage active discussion and exchange of ideas the workshop will be kept
small; the number of participants planned is around 40. The workshop will 
consist of a number of presentations and provide ample opportunity for 
technical discussions. 

Programme

The programme will consider three important themes:

Theoretical foundations - There are evolving theories which seek to generalize
elements of KBS development and V&V. For example, defining generic tasks (eg 
knowledge acquisition and representation), their associated problems, and the 
methods used to accomplish them. Can such theories help the developer to 
structure KBS verification and validation by delineating the kinds of task 
and information that are required to build confidence in a system's overall 
effectiveness? This theme will explore work being done to establish a 
well-founded approach to KBS verification and validation.

Tools and techniques - The process of verifying and validating a KBS can be 
greatly assisted by providing an environment in which the various participants
in a KBS development have ready access to knowledge representation schemes 
used to express knowledge statements and the inferences which can be operated 
on them, in a form which is easy to understand. This theme will explore the 
sorts of verification and validation tools currently being developed and 
assess their effectiveness.

Industry requirements - If KBS are to be successfully used to solve real-world
problems, then industry must have confidence in the technology and its 
application. For example, medical instrument companies need to establish for 
themselves and their customers that a knowledge-based drug administration 
system is sufficiently competent to be used by hospital staff. This theme will 
explore what industry requirements are and how these requirements are being 
met by current research.

One theme will be considered each day of the workshop. In the morning a series
of short presentations will be given by selected workshop participants on
their work; the list of papers to be presented is currently being reviewed by 
the workshop committee and will be finalized in May. The issues and questions
raised by these presentations will be discussed by small groups of 
participants during the afternoon.The findings of each group will be presented
to all workshop participants during a plenary session at the end of each day.

In addition to the core workshop activities, Professor Luc Steels (University
of Brussels) will give the workshop's keynote speech on Monday 22 July, Dr
Brian Oakley (Logica) will be the guest speaker at the workshop banquet on
Tuesday 23 July, and Dr Enric Plaza (CEAB) will give the closing speech on
Wednesday 24 July.

Subject: Philosophy & Computing CFP

Philosophy & Computing

The journal is devoted to the use of computers and computational ideas
in both research and teaching in philosophy, applications of ideas from
philosophy in computing, and philosophical questions about the
foundations and impact of computers and computational ideas. Examples of
the first include the development of computer programs for the discovery
of scientific theories (philosophy of science), work on automated proof
construction (logic), work on case-based reasoning (ethical theory),
material on the use of text-analysis software (history of philosophy),
and the description and evaluation of innovative computer-assited
instructional materials. Examples of the second include the application
of speech act theory to computer programming languages or the
application of work on metaphor and analogy to natural language
understanding. Examples of the last include topics in computer ethics,
work on the nature of knowledge and expert systems, and discussions of
the possibility of artificial life.

Philosophy & Computing is the official journal of CAP. For information

              -- Representation and Implementation Methods --

                  July 1-3, 1991  Kaiserslautern, Germany

The high description level of declarative representation formalisms 
facilitates readability, maintenance, and parallelization of knowledge 
bases; their orientation toward logic enables clear semantics. However, the 
processing of large declarative knowledge bases is becoming efficient only 
with the use of modern implementation techniques. For instance, the 
increased gap to von Neumann machines may be bridged by (global) static 
analysis and (multi-stage) transformation/compilation of the representation 
formalisms. The workshop addresses researchers and developers with 
interests ranging from logic programming to expert-system shells. Critics 
of declarative-knowledge processing (e.g. having procedural, object-
oriented, or connectionist points of view) are also welcome.

		"Psycholinguistic and Connectionist Investigations of
		Syllable Structure:  Implications for Language Representation"

				  Abstract

The characterization of representations  which  underlie our knowledge and
use of language  has  been  a  major  concern  of linguistic and psychological
theories of language.    However,  the  existence of specific representational
categories are often assumed by  the  very  theories which attempt to describe
them.    This  leaves  open  the  very  important  question  of  how  language
representations are instantiated.  The present paper discusses this problem in
relation to the representation of syllable structure.  First, psycholinguistic
data is presented which shows that  the  syllable  serves as a useful guide in
language recognition.  This data  provides  support for the view that syllable
structure  is  represented  in  the  mental  lexicon.    Second,  a  series of
Connectionist simulations are discussed  which  investigate the development of
syllable structure.  In one simulation  a  large natural language data base is
used to show that in  principle,  representations of syllable structure may be
derived from the regularities  present  in  a  language.   A second simulation
demonstrates how extracted  representations  may  be  used  to guide a morpho-
phonological process of  syllable  based  reduplication.    These results have
important implications  for  theories  of  the  mental  lexicon and linguistic
phonological representation.

	Text Classification: Statistical and Linguistic Issues

Computer text classification systems include systems for the
retrieval of documents in response to user queries, and systems for
categorizing documents with respect to a set of meaningful categories.
The recent resurgence of interest in information retrieval has been
accompanied by a new emphasis on the use of natural language
processing in text classification.  In this talk we discuss two 
experiments on using syntactic analysis of natural language text to
improve text retrieval performance.  The importance of considering
both linguistic and statistical concerns will be stressed in both cases.

In the first study, syntactic parsing is used to extract indexing
phrases from queries and documents.  These phrases have better
semantic properties than individual words, but inferior statistical
properties.  Feature clustering is then used to produce features which
are superior on both semantic and statistical grounds, and which
result in improved performance in a statistical retrieval system.  The
difficulty of comparing feature sets using conventional information
retrieval test collections will be briefly discussed, as will an
experiment which is in progress to evaluate this feature formation
method on a text categorization task.

In the second study, which is joint work with Bruce Croft (Univ.
of Mass. at Amherst) and Howard Turtle (West Publishing), syntactic
parsing of natural language queries is used in deciding how to
structure a Bayesian inference net for document retrieval.  This
automatic analysis of natural language queries produced retrieval
performance comparable to that obtained using hand structured queries,
and is a promising approach to effective use of dependence models in
text retrieval.
