Approach of Ontology Annotation Based on Background Knowledge
The lexical-based representation of ontology lead to the ambiguity and misunderstanding,we may inference the meaning of concepts by their context in some Ontologies,but some can not.To solve this problem,propose an approach for ontology annotation based on background knowledge.It consists of annotation approach and based on WordNet and approach based on Web search engine,search the right senses for the concept name,search the right snippets for the concept name,and annotate the senses and snippets into Ontologies as new properties.Experiment shows annotate ratio is 99.12%,which indicates the applicable of our annotation approach correct annotate ratio is 80.76%,does better than related approaches.
