Identifying query aspects

Abstract

Methods, systems, and apparatus, including computer program products, for generating aspects associated with entities. In some implementations, a method includes receiving data identifying an entity; generating a group of candidate aspects for the entity; modifying the group of candidate aspects to generate a group of modified candidate aspects comprising combining similar candidate aspects and grouping candidate aspects using one or more aspect classes each associated with one or more candidate aspects; ranking one or more modified candidate aspects in the group of modified candidate aspects based on a diversity score and a popularity score; and storing an association between one or more highest ranked modified candidate aspects and the entity. The aspects can be used to organize and present search results in response to queries for the entity.

Description

technical field

[0001] The present specification relates to providing information in response to a search query, identifying aspects of entities identified in the search query, and using these aspects in presenting information in response to the search query. Background technique

[0002] Internet search engines provide information about Internet-accessible resources (eg, web pages, images, text documents, multimedia content) in response to a user's search query and present information about these resources in a manner that is useful to the user. Internet search engines return sets of search results (eg, as ranked results lists) in response to queries submitted by users. Search results include, for example, URLs and excerpts of information from corresponding resources. Conventional search engines are implemented under the assumption that a user's search query can be satisfied by a single result, and serve to help the user discover the results. Unfortunately, users are not ...
