基于P2P的教育资源搜索引擎的研究

Design of Educational Resource Search Engine Based on P2P

该文构建一个基于P2P的教育资源分布式搜索引擎,根据教育资源所具的特点,引入元数据注册方案,优化了基于类别的混合P2P搜索模式,把资源请求的查找限定在小范围内,从而提高资源的发现速度,针对一般搜索引擎对教育资源搜索的高反馈率、低命中率问题,提出基于概率模型的资源相似度查找方式,以帮助用户快速准确地定位资源服务。

The major research effort of this paper is to build a P2P-based educational resource decentralized search engine.On the basis of the character of educational resource,a scheme of metadata registration is introduced and the hybrid P2P search of class-based is optimized.Then queries for resource are performed only in a small community,by which the efficiency of resource discovery can be improved.When using the common search engine to look for the educational resource,the feedback is always high while the hit ...
