摘 要:以农业网站作为抓取对象,在其特点分析基础上,基于J2EE设计并实现了面向农业主题搜索引擎,主要实现了网页信息抓取、处理、检索模块,完成农业信息网站内容的有效抓取,并实现数据输入、处理和输出的分离。在实现快速、分类、高级搜索等功能时,给出网页评分和信息分类,较好地表示搜索结果。系统的快速精确检索、开发周期短、维护成本低等性能特点不仅对农业信息主题检索有帮助,对其他领域信息检索以及对信息检索技术本身的应用研究也具有较好的参考价值。The current mainstream agricultural websites were considered in the paper,a search engine oriented on agriculture subject was designed according to the analysis of their functions and characteristics,which included website information crawling,processing and retrieving.In the design,the three modules,i.e.,the application data entry,processing and output were designed separately,based on J2EE architecture.The system achieved efficient information crawling of agricultural websites in China.And it also got the websites evaluation,information classification and good search results expression when rapid retrieval,intra-class retrieval and advanced retrieval were executed.The prompt and accurate information retrieval,the short development period and lower maintenance cost are not only helpful for agricultural subject,but also for the other fields and information retrieval technology itself.
