Efficient diversity-aware search
Albert Angel, Nick Koudas · 2011
Typical approaches of ranking information in response to a user's query that return the most relevant results ignore important factors contributing to user satisfaction; for instance, the contents of a result document may be redundant given the results already examined. Motivated by emerging applications, in this work we study the problem of Diversity-Aware Search, the essence of which is ranking search results based on both their relevance, as well as their dissimilarity to other results reported.
