Deep web数据集成需要对web查询接口进行模式匹配并获得映射关系.在web查询接口集成中引入语义冲突的概念,通过分析语义冲突的起源和分类,提出了一种基于本体的模式匹配方法.以房产领域的web查询接口集成为实例,详细阐述了这种方法的具体过程:通过比较语义相似度自动检测不同查询接口之间存在的语义冲突,识别冲突类别并且给冲突解决器发送消息,冲突解决器借助领域专家定义推理规则来消除冲突获得映射表.使用检测和解决语义冲突的方法来进行模式匹配,算法简单易于实现,扩充本体定义就可以使用于不同领域,灵活性和重用性较好.

Deep web data integration needs to do schema matching on web query interfaces and obtain the mapping table.By introducing semantic conflicts into web query interface integration and discussing the origins and categories of the semantic conflicts, an ontology-based schema matching method is proposed. The process of the method is explained in detail using the example of web query interface integration in house domain. Conflicts can be detected automatically by checking semantic relevance degree, then the categories of the conflicts are identified and messages are sent to the conflict solver, which eliminates the conflicts and obtains the mapping table using conflict solving rules. The proposed method is simple, easy to implement and can be flexibly reused by extending the ontology to different domains.
