基于循环进化的IETM领域本体构建研究

本体库是智能化IETM系统核心内容之一,信息检索和图形化呈现等后续操作都要基于本体库进行,所以需要在领域专家的帮助下,构建出一个合理的领域本体库。本文在遵循本体建模原则的基础上,综合贯通各种方法的优势,尤其是相对比较成熟的＂七步法＂,并借鉴软件工程领域的质量环思想,提出了一种新的领域本体建模方法——循环进化法。应用结果表明,所提循环进化本体构建法较好地解决了IETM系统领域本体的构建和存储问题,强调了本体构建的周期性和进化性,有效地克服了传统的七步法存在的改进性和扩展性差的不足。

Research on IETM domain ontologies based on cyclostationary evolution

A new method for constructing IETM domain ontologies is proposed based on cyclostationary evolution.Firstly,the basic principles and workflows for constructing IETM domain ontology are established,and the shortcomings of seven methods for constructing ontology are given.Secondly,by combining the advantages of the seven-step method and the quality circle,the cyclostationary evolution method is designed,and its seven steps are analyzed.Thirdly,the store method is also designed,and the map methods about the ontology and the data are given.Finally,the construct steps using Protégé are given,and sequently,the domain ontologies which is described by OWL language are obtained.The proposed method solves the construct and store problems of IETM domain ontology,and it emphasis on periodicity and evolutionary and can overcome the scalability limitation of the traditional seven-step method.
