FINAL CALL FOR PAPERS
=====================

Call for papers for the Second International Workshop on</H4>

VERIFICATION, VALIDATION AND INTEGRITY ISSUES IN
EXPERT AND DATABASES SYSTEMS

in conjunction with the Eleventh International Conference
on Database and Expert Systems Applications (DEXA'2000)

Greenwich, London; 6-8 September, 2000

GUEST SPEAKER: ALUN PREECE

Workshop proceedings to be published by IEEE

TECHNICAL DESCRIPTION
=====================
VVI'2000 aims to bring together the Expert Systems and 
Database research communities to explore common and
complementary issues relating to Validation, Verification 
and Integrity of Expert and Database Systems. The flavour 
of the distinction between the three VVI terms is given 
concisely in the following definitions:


Validation: Are we building the right product?
Verification: Are we building the product right?
Integrity: Are we keeping the product right?


The workshop will build on the success of the first VVI workshop 
(http://www.csc.liv.ac.uk/~frans/VandV/dexaWorkshop.html)
held in conjunction with DEXA'98 in Vienna) which established
common ground between the communities. The outcomes were:</P>

1. A conceptual model of where the two technologies come together.
2. A clarification of the VVI concerns of the two communities.
3. A set of "directions" for possible future "cross-over" research.

VVI'2000 seeks to develop and expand on these results by 
providing a forum for further interchange of ideas. Potential
participants are encouraged to contribute papers on any aspect 
of VVI. In particular the programme committee welcomes
contributions that discuss the application of "cross-over" 
technologies such as (but not restricted to):

1. The application of the ontologies concept (currently popular 
   in the context of KBS conceptualisation) to the design of DB 
   schema.
2. The use of DB representations for V&V of rulebases and the 
   use of rulebased approaches to address integrity considerations.
3. The V&V of the rule sets found in active and deductive databases.
4. The additional VVI problems encountered when applying OO 
   techniques to both DB and ES systems.
5. The special considerations that are applicable with respect to 
   VVI using CPS (Constraint Satisfaction Problem) techniques with 
   DB (Constraint databases) and with ES (Constraint logic 
   programming).
6. VV&I issues relating to the construction of federated information 
   systems which integrate existing database and/or expert systems.
