Experimental analysis of some computation rules in a simple parallel reasoning system for the ALC description logic

Adam Meissner (2011)

International Journal of Applied Mathematics and Computer Science

Similarity:

A computation rule determines the order of selecting premises during an inference process. In this paper we empirically analyse three particular computation rules in a tableau-based, parallel reasoning system for the ALC description logic, which is built in the relational programming model in the Oz language. The system is constructed in the lean deduction style, namely, it has the form of a small program containing only basic mechanisms, which assure soundness and completeness of reasoning....

Pipelined decomposable BSP computers

Martin Beran (2002)

RAIRO - Theoretical Informatics and Applications - Informatique Théorique et Applications

Similarity:

The class of weak parallel machines is interesting, because it contains some realistic parallel machine models, especially suitable for pipelined computations. We prove that a modification of the bulk synchronous parallel (BSP) machine model, called decomposable BSP (dBSP), belongs to the class of weak parallel machines if restricted properly. We will also correct some earlier results about pipelined parallel Turing machines.

A logic-based environment for developing natural language processing applications

Gérard Milhaud, Élisabeth Godbert (1998)

Mathématiques et Sciences Humaines

Similarity:

We present a system providing a set of tools for developing natural language processing (NLP) applications such as natural language interfaces, communication aid systems, etc. This system is based on two principles: modularity of knowledge representation to ensure the portability of the system, and guided sentence composition to ensure transparency, i.e. to ensure that the produced sentences are well-formed at the lexical, syntactic, semantic and conceptual levels. We first describe...
