Research on semantic environment-based annotation techniques for knowledge semantic

This paper puts forward the Semantic Environment-based Annotation Techniques for Knowledge Semantic in allusion to the problem in dealing with synonymy and in neglecting semantic environment. It improves the Algorithm on key link of ontology annotation. It is from two way that when calculating the correlation degree of word & document, one is to calculate the correlation degree of the “Example Annotation-Document”, the other hand is to calculate the co expression of the “semantic environment”. The efficiency of the annotation had been significantly increased through improving of Algorithm.
