Ontology-Based Information Extraction Technology

The performance of information extraction can be effectively improved through use of ontology. Based on the discussion of constructing ontology technology and standards related to, on the basis of three layers framework to constructing ontology to resume ontology, university teachers Racer reasoning machine to implement consistency and accuracy testing. Based on this improved the WordNet similarity calculation, through the use of WordNet semantic similarity calculation and manually collecting method of combining the concept of this body, obtain the specific examples, the result proves that the result can be extracted remarkably enhanced.
