集成桌面搜索引擎的内容检测系统设计

摘要

To meet the demand of real time monitoring internal information for enterprise,model of integrated desktop search engine as important functional unit in the content detection system is proposed.By studying the framework model of traditional desktop search engine,a special desktop search engine is designed to adapt actual demand.This desktop search engine based on document conversion and content crawling indexed for the searching keywords instead of the full-text indexing policy,which effectively avoids the disadvantages of spending a long time for Full-text indexing and improves the pertinence of the index.Lastly,a matching algorithm is discussed,which is selected to increase system performance.Experimental results proved that this design of content detection system by integrating desktop search engine manages and tests content from disks,ensure the security of desktop content.%针对企业需要对内部PC的磁盘信息进行实时监控的需求,提出了将桌面搜索引擎作为重要功能单元集成在检测系统中的设计模型.通过研究传统桌面搜索引擎的框架模型,设计出适应实际需求的特殊桌面搜索引擎.在文档转换和内容抓取的基础上为被搜索关键字建立索引,以此取代全文索引的策略,有效避免了建立全文索引用时较长的弊端,提高了建立索引的针对性.讨论了为提高系统性能而选择的匹配算法.实验结果表明,设计的内容检测系统通过集成桌面搜索引擎,能够高效地管理和检测桌面内容.
