摘要
对BBS的数据结构进行了分析研究,并根据BBS特点设计了一种用于BBS信息检索的主题网络爬虫算法.通过主题网络爬虫能够提高抓取网页的效率,同时又可以保证较高的召回率.实验表明,该算法大幅提高了信息检索的效率,改善了信息检索的效果.
The architecture of BBS is analyzed. And a suitable focused crawling algorithm is proposed, which improves the efficiency. A BBS search engine is designed based on the proposed algorithm. Practical experiments have been carried out, which show that the recall ratio as well as the accuracy of searching has been enhanced.
