针对不同领域本体之间存在的异质性,以及本体之间存在语义分歧、难以协同操作,从而影响本体复用与知识共享的现实问题,以当前成熟的领域本体为研究对象,通过在共同语义基础上对异质领域本体的概念格解析,在不破坏偏序关系的情况下获得本体中相关概念的外延与内涵,进而借助基于对象(外延)与属性(内涵)的概念相似度计算方法建立跨本体的映射,并最终构建多本体协同知识地图,实现跨越异质本体的知识呈现与知识检索.%For the heterogeneity between different domain ontologies, and semantic differences between thernontologies, difficult to co-operate, thus affecting the reuse of ontology and sharing of knowledge. This article makes the mature domain as the object of study, through the resolving by concept lattice of heterogeneity domain ontologies based on common semantic foundation, the extension and intension of related concepts are acquired with maintaining the partial order. The cross-ontology mappings are established via the computing method of concept similarity based on object (extension) and attribute (intension). Ultimately, multi-ontologies collaboration knowledge-map is constructed, and achieves knowledge presentation and knowledge retrieval across heterogeneous ontologies.
