科学搜索引擎Scirus的工作流程初探

How Scientific Searth Engine Scirus Works

随着信息技术的飞速发展和信息量的快速增长,人们面对的是浩如烟海的信息,如果没有搜索引擎的帮助,要想从中获得自己所需要的信息并非易事,特别是对于科学的、专业领域信息的搜索更是如此。Scirus正是迎合了这一信息需求,作为一个科学搜索引擎出现了。Scirus凭着优秀的搜索表现,连续三年被“搜索引擎观察”评为最佳专业搜索引擎。文章介绍了科学搜索引擎Scirus的倒金字塔结构的工作流程以及对“相似结果”的处理原理。

As information technology is developing very fast and the mount of information is growing, what people face is a great deal of information. Without the help of search engines, it will be very hard to find scientific or special information we need. Scirus, which is a kind of scientific search engine, does feed people＇s need. It works well, and won the honor of ＂the best specialty search engine＂ of Search Engine Watch for three years. The paper gives a brief introduction to Scims. We study its work flow, and try to find out how Scims could ＂pinpoint results＂, and how it find out ＂similar results＂.
