Diversity Within Search Results

摘要

Increasing diversity of search results is described. In one embodiment, a computing device obtains initial search results based on a search query. From among non-indexed attributes of the initial search results, an attribute is selected by which to diversify the initial search results. A latent group of search results is determined from among the initial search results based on the attribute, and a relevance score of at least one search result in the latent group of search results is changed. Further, results are provided in response to the search query. In one embodiment, the results include at least a portion of the initial search results and at least a portion of the latent group of search results based on the changed relevance score of the search results in the latent group.

主权项

1. A non-transitory computer-readable medium embodying a program executable in a computing device, the program, when executed by the computing device, directing the computing device to at least:
perform an item search in accordance with a search query to produce initial search results; identify a most relevant search result from among the initial search results; identify at least one other search result that is similar to the most relevant search result; discount a relevance score of the at least one other search result; identify a subset of search results from among the initial search results, the subset of search results including the most relevant search result and being based at least in part on the discounted relevance score of the at least one other search result; and provide the subset of search results in response to the search query.
