On the Importance of Being Diverse

Maurice Coyle, Barry Smyth

Web search engines place a significance emphasis on the similarity between the current query and the results when it comes to selecting and ranking a result-list. We argue that this query-similarity emphasis may limit search precision. We draw on related work by the case-based reasoning (CBR) community, which shows how enhancing result diversity can improve the quality of retrieved cases and recommendations. We evaluate the use of such techniques in Web search, showing that similar benefits are available.

Keywords: Web search, similarity, diversity
