Abstract

A set of measurements is proposed for evaluating Web search engine performance. Some measurements are adapted from the concepts of recall and precision, which are commonly used in evaluating traditional information retrieval systems. Others are newly developed to evaluate search engine stability, an issue unique to Web information retrieval systems. An experiment was conducted to test these new measure- ments by applying them to a performance comparison of three commercial search engines: Google, Al- taVista, and Teoma. Twenty-four subjects ranked four sets of Web pages and their rankings were used as benchmarks against which to compare search engine performance. Results show that the proposed mea- surements are able to distinguish search engine performance very well.

测量的基础上,提出了一套评价网络搜索引擎的性能。有些测量是改编的查全率和查准率的概念,它通常被用于评估传统信息检索系统。别人是一种新型的评价问题,搜索引擎稳定性的独特网络信息检索系统。摘要本实验测试了这些新措施,通过应用到期限的性能对比三个商业搜索引擎谷歌,艾尔- taVista:,Teoma。24科目排名第4套网页和他们的排名是作为基准,以比较搜索引擎的性能。结果表明,所提出的手段——surements可以分辨出搜索引擎的性能很好。
