在web信息集成领域,为消除语义异构、实现语义融合,将分类本体引入WWW信息集成,设计了一种基于本体集成的web信息集成系统.通过构建标准分类本体以获取局部分类本体,并建立二者间的映射,以获得多源统一视图.通过计算概念间的统领匹配度、关联匹配度、从属匹配度来完成概念的映射.实现了基于分类本体的web信息集成系统,该系统能很好地解决web信息分类语义异构问题,并能实现多web信息源的集成以及用户个性化定制.
In the field of web information integration, in order to eliminate the semantic heterogeneity and realize the semantic fusion, the classification ontology is introduced into the WWW information integration, and a web information integration system based on ontology integration is designed. By constructing the standard classification ontology to obtain the local classification ontology, The mapping between the two to get a multi-source unified view.Concept mapping is done by calculating the leading matching degree, the relevance matching degree and the subordinate matching degree between concepts.The web information integration system based on classification ontology is realized, Good solution to web information semantic heterogeneity problems, and to achieve the integration of multiple web information sources and user customization.
