Research On Oontology Merging Method Based On Attribute Reduction Of FCA And Concept Lattice

The purpose of this article is based on formal concept analysis and attribute reduction,a new method of ontology merging,aimed at resolving the ontology merging technology in the field of information science and information science are widely used,and the lack of mature and effective ontology merging method for its support.At present there have been many researches on ontology merging,and also developed some ontology merging system,but there are some problems in these methods :(1)the need for ontology merging domain experts to participate in,more time-consuming,laborious and affected by human factors is too large.(2)in the same field,different experts may adopt different viewpoints,which can lead to the inconsistency of the result of the merger.Therefore,in order to solve these problems,this paper proposes an ontology merging method based on formal concept analysis and attribute reduction,and introduces the collective wisdom into the ontology construction process.With formal concept analysis and concept lattice for the method of attribute reduction theory as the breakthrough point,first gives the concept lattice and ontology is introduced,and then on the basis of the analysis put forward a kind of attribute reduction based on formal concept analysis to ontology merging model,the model of existing ontology merging method is optimized,attribute redundancy in the process of ontology construction has carried on the corresponding processing,select out the core of the field and the relative necessary attribute,remove unnecessary properties,thus better accepted by the public,more conducive to find,in the end,based on the field of film as an example,the availability of new methods for experimental verification,to prove the availability of this method.The innovation of this article is based on formal concept analysis is constructed and the attribute reduction of a new model of ontology merging based on formal concept analysis is put forward and the attribute reduction,a new method of ontology merging,optimized in ontology merging method theory.The research results of this paper is based on formal concept analysis is clear and the basic principle of attribute reduction of ontology merging method,phase partitioning,based on formal concept analysis is constructed with ontology merging method model of attribute reduction,and concrete into the model based on formal concept analysis and attribute reduction method of ontology merging the concrete process of the domain ontology in the information and related disciplines for each application in the field of play a good role in promoting,and innovated for thedevelopment of domain ontology construction method.
