摘要
经过分析本体原型系统中存在的关键问题,提出基于FCA的本体原型系统来弥补缺陷,并阐明了系统的主要特色是采用FCA技术进行本体的构建、合并、三维可视化展现,其中为了在本体展现中简化概念格的显示,提出子概念格的判定方法。最后通过实例,从领域中生成了所有隐含的本体概念,形成了概念之间的上下级关系,结合相关性几率模式给出了非层次级概念之间的相似性以及概念与对象之间的相关度,从而提高了用户在本体中的查询效率。
After analyzing key problems in ontology prototypal system,ontology prototypal system based on FCA （Formal Concept Analysis） is presented to make up these defects,and-elucidates that main feature of the system is ontology building,merging and three-dimensional visualization display.This system proposes the determination of sub-concept lattice in order to reduce display.By examples,all of connotative ontology concepts were created from field,a superior-subordinate relationship was formed among concepts,and comparability among non-level class concepts and relativity between concepts and objects were gave by combine interrelated probability mode,thus inquiring efficiency among ontology was improved.
