面向用户的本体爬虫研究与设计

Research and design of user oriented onto-crawler

针对传统搜索引擎不能满足用户个性化、专业化需求的缺点,提出了一种面向用户和领域本体的搜索策略,设计了一个面向用户的本体爬虫系统.该系统采用改进的获取领域相关信息的检索策略来获取信息,并且在爬虫内部设计了用户定义的优先队列.实验证明,该系统提高了页面查询的精确率和召回率.

Traditional search engines can＇t satisfy the individuatation and specialization demands of users.A search strategy was proposed both user-oriented and domain-oriented and a user-oriented onto-crawler system was designed.An improved access to areas of information related to key policy is adopted to obtain information.A user defined priority list in the internal of the crawler was designed.Experiments showed that the system had improved page query precision and recall rate.
