摘要
Web数据抽取与集成的目的是提供面向领域的增值服务,结合领域数据特征,提出Web数据模式与领域数据模型.给出了基于Web数据模式的数据定位、抽取与基于领域数据模型的集成算法,并结合行业领域的需求,验证了模型和算法的有效性.
The purpose of web data extraction and integration is to provide the value-added services. Analyzing the features of domain data, the paper proposes web data schema and domain data model. It also puts forward the data positioning and extracting on the base of web data schema and an integration algorithm according to do the main data model. The application results are given to show effectiveness of the proposed algorithm and model.
