面向BBS的关键词搜索引擎系统的设计

Design of Keyword Search Engine System for BBS

BBS搜索系统是为公安系统等监管部门了解年轻人思想动态,及时发现证据,防止案件发生而建立的.针对如何搜索各BBS上把符合搜索要求的信息检索出来,设计了一个面向BBS的关键词搜索引擎系统.首先从BBS搜索系统的需求分析入手,其次进行技术分析和方案设计,同时提出了一个索引倒排的索引算法,以此并设计了一个检索器将检索结果呈现,最后参考典型搜索引擎的实现,完成了一套小型的针对BBS进行扒取和检索的系统.目前该系统运行良好,结果表明该系统性能高,易于维护。

The BBS search system is for the public security system and other regulatory authorities to understand the young people＇s ideological trends,and for finding evidence to prevent the occurrence of the case.For how to search the information retrieved from each BBS,a keyword search engine system for BBS was designed. Firstly,BBS search system＇s needs were analyzed. Secondly,the technology was analyzed and designed.At the same time,an index inverted indexing algorithm was proposed in order to retrieve results. A searcher was designed. Finally,referring to the realization of the typical search engine,a set of small for BBS for grilled and retrieval system was designed. At present,the system runs well. The results show that the system is of high performance and easy to maintain,and has some reference to the same research.
