Abstract

An important indicator of a maturating Internet is the development of metrics for its evaluation as a practical tool for enduser information retrieval. However, the Internet presents specific problems for traditional IR measures, such as the need to deal with the variety of classes of retrieval tools. This paper presents a metric for comparing the performance of common classes of Internet information retrieval tool, including human indexed catalogs of web resources and automatically indexed databases of web pages. The metric uses a relevance-based quantitative measure to compare the performance of endusers using these Internet information retrieval tools. The benefit of the proposed metric is that it is relevance-based (using enduser relevance judgments), and it facilitates the comparison of the performance of different classes of IIR tools
