摘要
Deep Web信息按需集成研究的是如何根据用户的需求从海量的Web数据库中获取所需的信息.本文在对近10年来该领域研究进行综述的基础上,提出Deep Web信息按需集成框架,它包括Deep Web搜索引擎、接口集成、数据源描述、查询执行等4个方面内容.同时,围绕用户的个性化、查询结果的用户满意度和查询效率等评价指标,对Deep Web按需集成的未来发展方向进行展望.
Requirement-oriented integration of Deep Web information refers to acquiring meaningful information from tremendous Web databases according to users; needs. On the basis of the research survey in the past 10 years, a new framework for the requirement-oriented integration of Deep Web information is proposed, which is composed of four components: search engine for Deep Web, interface integration, source description and query execution. According to this framework, the research work in the last decades classified and discussed in-depth. The key evaluation factors of the requirement oriented integration for Deep Web information are concluded, namely, personalization, user's satisfaction and query efficiency. At last, the suggestions for future research directions are pointed out.
