基于本体的Deep Web数据标注

Ontology-Based Annotation for Deep Web Data

借鉴语义Web领域中深度标注的思想,提出了一种对Web数据库查询结果进行语义标注的方法.为了获得完整且一致的标注结果,将领域本体作为Web数据库遵循的全局模式引入到查询结果语义标注过程中.对查询接口及查询结果特征进行详细分析,并采用查询条件重置的策略,从而确定查询结果数据的语义标记.通过对多个不同领域Web数据库的测试,在具有领域本体支持的条件下,该方法能够对Web数据库查询结果添加正确的语义标记,从而验证了该方法的有效性.

A semantic annotation method for Web database query result is proposed in this paper by adopting the deep annotation procedure in semantic Web. As a global schema Web database should be followed, domain ontology is introduced to the annotation procedure for a completed and consistent annotation result. The query interface and the query result features are analyzed in detail, the strategy of query condition reconfigured is adopted, and then the semantic markups of query result are determined. By collecting Web database from different domains, the experiments indicate that the approach proposed can annotate the Web database query result properly under the support of domain ontology.
