                       INTERNATIONAL WORKSHOP on

                   PROCESSING DECLARATIVE KNOWLEDGE

           -- Representation and Implementation Methods --

               July 1-3, 1991  Kaiserslautern, Germany


Background:

Declarative representation formalisms have long constituted the kernels 
of AI languages. Their high description level facilitates readability, 
maintenance, and parallelization of knowledge bases; their orientation 
toward logic enables clear semantics. This becomes especially important 
when several formalisms are used in a 'hybrid' fashion,  as the 
amalgamation of sublanguages is simplified.
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. Experimental methods for most 
representation and implementation layers exist, which should gradually 
enter practical AI, e.g. via expert-system shells.


Scope:

This workshop will provide an opportunity to present promising approaches 
for processing declarative knowledge, to demonstrate implemented systems, 
and to meet with AI practitioners. Also welcome are well-founded 
critiques of declarative-knowledge processing (e.g. from procedural, 
object-oriented, or connectionist points of view).
Besides representation formalisms on the basis of horn-logic programming 
it is possible to present, among others: more general inference rules 
(backward/forward chaining), concept-description languages (subsumption 
procedures), as well as constraint or constraint-logic-programming 
systems (propagation algorithms).
Regarding implementation, all recent interpretation and especially 
compilation techniques will be of interest, e.g.: abstract 
interpretation, partial evaluation, rule compilation, and WAM technology.


Paper Submission:

Please submit four (4) copies of papers written in English by 1 March 
1991 (not via email). If electronic mail is available, additionally email 
an ASCII version of the abstract. Refereeing will take place in two 
categories: Long papers of max. 20 pages for full-blown research results, 
short papers of up to 6 pages for concise presentations and partial 
results. In both categories we expect original work. Authors will be 
notified of acception or rejection of submitted papers by 30 April 1991, 
the camera-ready revisions are due by 10 June 1991. Applications for 
system presentations consisting of a system mini-description of 1-3 pages 
as well as a specification of the hardware/software required should 
arrive by 3 June 1991. Please direct contributions and requests to the 
following address:
