Granular Rules and Rule Frames for Compact Knowledge Representation

摘要

Efficient management of big Rule-Based Systems constitutes an important challenge for Knowledge Engineering. This paper presents an approach based on Granular Sets and Granular Relations. Granules of data replace numerous low-level items and allow for concise definition of constraints over a single attribute. Granular Relations are used for specification of preconditions of rules. A single Granular Rule can replace numerous rules with atomic preconditions. By analogy to Relational Databases, a complete Granular Rule Frame consists of Rule Scheme and Rule Specification. Such approach allows for efficient and concise specification of powerful rules at the conceptual level and makes analysis of rule set easier. The detailed specifications of Granular Rules are much more concise than in the case of atomic attribute values, but still allow for incorporating all necessary details.
