【摘要】 针对农业信息查找困难的问题,设计和实现了一个基于农业元数据元素集(AgMES)的搜索引擎原型系统。在归纳总结元数据标记技术的基础上,确定该引擎支持的文件格式,提出了该引擎的工作原理,设计了支持在Internet上抓取AgMES文件的Sipder程序,设计了几种AgMES文件解析器,使用Java技术实现了该搜索引擎的原型系统。该引擎可对基于AgMES的、用HTML、XML、RDF、RSS等不同格式标记的农业元数据信息进行搜索。更多还原

【Abstract】 Focus on the problem that hard to find suitable agricultural information,designed and implemented a prototype of AgMES based search engine. Overviewed and concluded the markup technology of metadata and worked out the different file formats the search engine should support, proposed the principle of AgMES based engine, designed a spider program to fetch AgMES files from internet, designed several AgMES file parser, implemented the prototype of the engine using Java language. The engine can precisely search agricultural information which described with AgMES in different file formats such as HTML, XML, RDF and RSS.更多还原
