摘要 Deep Web能够提供大量高质量的信息,为了有效地利用这些信息,建立Deep Web数据集成系统是重要手段。Deep Web数据集成系统的查询效率是其应用的关键。本文采用建立本地索引数据库的方式以提高查询效率,在此基础上提出了其相应的更新策略,并给出了算法分析。 Deep Web can provide us a great amount use of the information, it is important to establish data integration system, query efficiency is the key of high quality information. In order Deep Web data integration system. to make full In Deep Web to its application. In this paper, we clarify aod to improve query efficiency by establishing the local index database. Based on this, we present its corresponding update strategy and then expound the algorithm analysis.
