COVERAGE AND INDEPENDENCE - Defining Quality in Web Search Results
Panagiotis Metaxas, Lilia Ivanova · 2008
Abstract: Web search results enjoy an increasingly greater importance in our daily lives. But what can be said about their quality, especially when querying a controversial issue? The traditional information retrieval metrics of precision and recall do not provide much insight in the case of the web. In this paper we examine new ways of evaluating quality in search results: coverage and independence. We give examples on how these new metrics can be calculated and what their values reveal regarding the two major search engines, Google and Yahoo. 1
