Evaluating reward and risk for vertical selection
Ke Zhou, Ronan Cummins, Mounia Lalmas, Joemon M. Jose · 2012
The aggregation of search results from heterogeneous verticals (news, videos, blogs, etc) has become an important consideration in search. When aiming to select suitable verticals, from which items are selected to be shown along with the standard "ten blue links", there exists the potential to both help (selecting relevant verticals) and harm (selecting irrelevant verticals) the existing result set.
