Abstract
Disclosed are various embodiments for increasing diversity of search results. A computing device performs a search of items in an electronic catalog to produce a plurality of search results. The electronic catalog is stored in a data store accessible to the computing device. A latent group is identified which includes a most relevant one of a plurality of search results. Each of the search results has a plurality of attributes. Membership in the latent group is determined by similarity of a non-indexed one of the attributes. A relevance score of those search results in the identified latent group other than the most relevant one of the search results is reduced.
