A Concise Integer Linear Programming Formulation for Implicit Search Result Diversification
WSDM, pp. 191-200, 2017.
To cope with ambiguous and/or underspecified queries, search result diversification (SRD) is a key technique that has attracted a lot of attention. This paper focuses on implicit SRD, where the possible subtopics underlying a query are unknown beforehand. We formulate implicit SRD as a process of selecting and ranking k exemplar documents...More
