.Net平台下知识网络系统及其搜索引擎的设计与实现

Design and implementation of knowledge network system and search engine based on.Net Platform

针对目前学习平台中信息简单罗列、组织层次不清晰的问题,利用.net平台上的ASP.Net、Silver Light技术设计实现了一个B/S架构的知识网络系统。分析了树形结构的特点,提出了递归寻路径法,将知识信息层次清晰地展现给用户,并实现节点间路径的获取。通过对Lucene.Net全文检索技术的研究,将其与SQL Server数据库的索引技术相结合,实现了一个高效的检索引擎。

Aiming at problems about information was simple enumerated and organizational levels of knowledge was not clear in current learning platform,the networked knowledge system with B/S structure is designed and implemented by using ASP.Net and SilverLight technology of.Net platform.This paper analyses the character of tree structure,and proposes the method of searching path by recursive algorithm.With these,the knowledge and information are clearly presented to the user,and the path between nodes is acquired.The technology of full-index and full-text based on Lucene.Net are analyzed,and Lucene.Net is combined with the SQL Server database indexing technology.Based on this,the efficient search engine is established.
