Semantic Field Model

Abstract:

This paper applies the field theory to semantic space and puts forward the semantic field model, which depicts the interaction between ontology concepts and the distribution law of semantics. First, this paper formally defines and describes the semantic field from the perspectives of potential, gradient and intensity. The potential represents the semantics of a certain position in the semantic field; the gradient describes local semantics change of the semantic field; and the field intensity reflects the strength of semantics association among concepts. Then, we discuss the influence scope of field sources, mass calculation of ontology concepts and the optimal selection of influence factor. Finally, the paper shows us the application prospects of semantic field in semantic-based resource clustering, semantic-supporting P2P application system and evolution analysis of ontology knowledge
