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.
