SSOA: a Semantic Service-Oriented Architecture Based on Fuzzy Assertion System

摘要

This paper proposes the SSOA (Semantic Service-oriented Architecture) based on formal and distributed ontologies, and the knowledge baseframed by ontology and the fuzzy reasoning system oriented to agent cognition are considered to prescribe and treat the uncertainty of agent cognizing. The SSOA includes two essential components. Knowledge Base Supported by Formal Ontology and Agent-oriented Fuzzy Reasoning System. First, Knowledge Base Framed by Formal Ontology builds a concept hierarchy organized by inclusion relation, and uses those concepts to describe specific objects to form assertions of an application domain. Agent-oriented Fuzzy Reasoning System then incorporates plausibility degree into assertions of certain agent, and the alphabet of symbols, well-formed formulas, axioms and inferences rules are constructed respectively. The SSOA architecture constructs a fundament for services interaction and composition automatically under open environment.
