Ontology is divided into lightweight and heavyweight ontology,lightweight ontology consists of terminology,concepts and classification of relationships.Heavyweight ontology is constituted by adding non-taxonomic relationship and axiom on the basis of a lightweight ontology.The former focuses on the knowledge structure of expression,but the latter has stronger semantic and logical reasoning function,which is more suitable for the semantic processing of information and the discovery of new knowledge.According to the reverse and symmetric axiom of language schema,the original non-taxonomic relationship model is constructed,and then extends of the generated model by using a lightweight ontology.At the same time,combined with the party's present value method of statistics,this approach extracts axioms in the field of agricultural plant diseases and insect pests,and only improves the efficiency of axiom,but has been applied in the field of Chinese Language to extract of the reverse axiom and symmetric axiom.
