摘要 介绍面向侨务信息主题搜索引擎的工作原理和体系结构,根据侨务信息的特征对网页进行侨务信息的识别.针对主题式搜索,提出一种优化的,基于历史反馈(BHF)的搜索策略,并对该搜索策略进行实验测试.结果表明,以该方法设计的面向侨务信息主题的搜索引擎系统,具有较高的搜索速度与识别精度. In this paper, we first introduced the work principle and the framework structure of topic-special search engine for the information about overseas Chinese affairs. We found a way to identify the information of the overseas Chinese affairs on the suitable web page based on the characters of the information about the overseas Chinese affairs. By this topicspecial searching, the paper brought forward an optimization search strategy which is based on historical feedback (BHF). At the end, we took an experiment on this search strategy. The results show that, this search engine system has a high search speed and identify precision.
