When an ambiguous query is received, a sensible approach is for the information retrieval (IR) system to diversify the results retrieved for this query, in the hope that at least one of the interpretations of the query intent will satisfy the user. Diversity is an increasingly important topic, of interest to both academic researchers (such as participants in the TREC Web and Blog track diversity tasks), as well as to search engines professionals. In this workshop, we solicited submissions of both technical papers and position papers on three themes: approaches and models for diversity; the evaluation of diverse search results; and on applications of diverse search results. In the workshop, two invited talks, along with ten refereed papers were presented before breakout groups considered questions and issues with the three workshop themes.
