摘要
In order to eliminate semantic heterogeneity and implement semantic combination in web information integration, the classification ontology is introduced into web information integration. It constructs a standard classification ontology based on web-glossary by extracting classified structures of websites and building mappings between them in order to get unified views. Mapping is defined by calculating concept subordinate matching degrees, concept associate matching degrees and concept dominate matching degrees. A web information integration system is realized, which can effectively solve the problem of classification semantic heterogeneity and implement the integration of web information source and the personal configuration of users.
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.
