Weight Determine Method for Comprehensive Similarity Calculation about Concept of Ontology
Cheng Jinhu · Journal of Jilin University(Science Edition) · 2014
Using the theory of rough set and conditional information entropy,we presented a strategy to automatically determine the weight in connection with determining weight in integrated similarity calculation relying too heavily on domain experts in the ontology mapping method based on similarity calculation.In full consideration of uncertain information using the influence degree of each attribute on the system information entropy to determine each attribute's weight in the current information system made the automatic mapping of ontology and semantic network real-time services possible.At last,the feasibility of this method was verified by examples.
