In order to solve that the current ontology technologies which mainly depended on the participation of experts in the field and were not objective enough,the thesis presented an ontology setting up technology with a combination of concept lattice and statistical study.First,counted the appearance probability of terms in the document by statistical arithmetic.Second,set up threshold of terminology extraction,noted the records of the files in which terminology appeared, and organized the concept lattices of knowledge organization-level relations.Finally,transformed the concept lattice into ontology.Practice shows that this method of setting up ontology has good objectivity, and can greatly improve the efficiency of ontology search.
