A class of Probabilistic Abductive logic Programs (PALPs) is introduced and an implementation is developed in CHR for solving abductive problems, providing minimal explanations with their probabilities. Both all-expla...

We describe a proof dedicated meta-language, called
L
tac , in the context of the Coq proof assistant. This new layer of meta-language is quite appropriate to write small and local automations.
L
tac , is essentially a small functional core with recursors and powerful pattern-matching operators for Coq terms but also for proof contexts. As
L
tac , is not complete, we describe an interface between
L
tac , and the full programmable meta-language of the system (Objective CAML), which is also the implementation language. This interface is based on a quotation system where we can use
L
tac ,'s syntax in ML files, and where it is possible to insert ML code in
L
tac , scripts by means of antiquotations. In that way, the two meta-languages are not opposed and we give an example where they fairly cooperate. Thus, this shows that a LCF-like system with a two-level meta-language is completely realistic.
The basic polarized process algebra is completed yielding as a projective limit a cpo which also comprises infinite processes. It is shown that this model serves in a natural way as a semantics for several program alg...

LogiMOO is a BinProlog-based Virtual World running under Netscape or Internet Explorer. It is user extensible and supports distributed group-work over the Internet. Virtual places, virtual objects and agents are programmable through a "controlled English" interface.
Answer set programming (ASP) is a popular declarative programming paradigm with various applications. Programs can easily have many answer sets that cannot be enumerated in practice, but counting still allows quantify...

The paper presents a spatial logic, called PISL-2D, and an implementation of its inference engine, called SpInE. The approach can be used to represent spatial knowledge in a 2-dimensional space using a set of qualitative spatial relations. The formalism is based on a point-interval logic and a graphical representation, called Point Graphs. The graph representation is used by SpInE to verify and infer spatial knowledge.

We show how several novel tools in logicprogramming for AI (namely, continuation based linear and timeless assumptions, and datalog grammars) can assist us in producing terse treatments of difficult language processing phenomena. As a proof of concept, we present a concise parser for datalog grammars (logic grammars where strings are represented with numbered word boundaries rather than as lists of words), that uses assumptions and a combination of left-corner parsing and charting. We then study two test cases of this parser's application: complete constituent coordination, and error diagnosis and correction.
In this paper we define a many-valued semantics for hybrid logic and we give a sound and complete tableau system which is proof-theoretically well-behaved, in particular, it gives rise to a decision procedure for the ...
