基于RSS的搜索引擎技术及其发展趋向探析

Study on Technical Features and Development Based on RSS Search Engine

随着RSS资源的飞速增长,基于RSS的搜索引擎应运而生。RSS搜索引擎的使用方法和Google、百度一样,都是通过输入关键词来搜索要查询的内容。不同的是传统门户搜索引擎是对抓取到的网页内容进行搜索,而RSS搜索引擎则是直接对RSS种子或含有RSS种子的网页进行检索。RSS搜索引擎具有高度准确性、动态聚合机制和高效率、高速度的搜索特点,为当前网络资源最为重要的新型信息检索工具。鉴于此,本文就RSS搜索引擎的国内外研究状况、技术特点和应用机理等进行了初步探讨,在此基础上,笔者进一步对基于RSS的搜索引擎技术进行了展望。

With the rapid growth of RSS resources, RSS search engine came into use. Using RSS search engine has the same way with Google and Baidu. That means you can enter key words to search the queries. What is different is that traditional search engines process searching through crawling page content, while RSS search engine directly searches RSS seeds or pages which contain RSS seeds. RSS search engine has the characters of high degree of accuracy, dynamic polymerization mechanisms, efficiency and high-speed, which becomes the most important new information retrieval tool for network resources. In view of this, the paper focuses on the research situation at home and abroad, principles, technical features and development trend of RSS scarch engine.
