Research On Knowledgechains-based Ontology Construction Methodology

The term "ontology",derived from philosophy,means that the explaining and interpreting for objective being.Recently years,it rapidly developed in AI, computer science and knowledge engineering.Ontology could realize the sharing an reusing for knowledge in some degree,result that computers could understand the information and language in the semantic level,in some degree resolve the problem of semantic isomery,it has a great applying foreground in information interoperability,knowledge understanding and information integration field.But, because the time of introducing ontology into AI,information system etc.is not too long,the method of building ontology is established primarily,if there is no good method as guideline,it is hard to keep accord in building different ontology, is bad to ontology construction in scale and criterion.Therefore,it is extremely important for ontology applying to research building domain ontology method.Because the research of ontology construction methodology has been a hotspot,the paper deeply studies ontology construction methodology in the world, and deeply understands and analyses the basic concepts and construction principles,and references existing ontology retrieving method,propose a knowledgechains-based ontology building method.This methodology uses knowledgechains to achieve the retrieving of ontology concept,relation and constrain;referencing knowledge engineering methodology to improve the existing ontology construction methodology;on the base of the characteristic of knowledgechains schema,proposing a new arithmetic of concepts clustering to generate concepts classify ranks automatically to achieve the ontology construction.Besides,we introduce existing ontology evaluation method and evaluation tools.Finally,the paper presents in detail how to building Airline Booking Ontology in the aid of methodology of knowledgechains-based ontology construction method and Protégéas a ontology editing tool.
