Providing supplemental information in news search
In one aspect, a method includes receiving a query, identifying search results in response to the query, grouping the search results into one or more clusters, identifying similarities across the one or more clusters, determining a related topic associated with the query based on the similarities of the one or more clusters, determining a categories associated with the query, identifying supplemental information based on the related topic and the category, and providing the search results and the supplemental information for display in response to the query.
1. A computer-implemented method, for providing supplemental information in response to a search query comprising:
receiving, by a computing system comprising one or more computing devices, a search query comprising criteria for retrieving a set of search results, wherein the criteria comprises one or more search terms or phrases;
retrieving, by the computing system, the set of search results from a vertical search engine, wherein the vertical search engine comprises a news search engine, wherein the set of search results comprise one or more content items that meet one or more criteria of the search query;
identifying, by the computing system, one or more similarities between the one or more content items of the set of search results, wherein the one or more similarities comprise at least one of a similar content, a similar topic, a similar genre, or a similar date of generation;
generating, by the computing system, one or more search clusters based on the one or more similarities between the one or more content items, wherein each of the one or more search clusters comprise at least one of the one or more content items;
identifying, by the computing system, one or more common terms associated with each of the one or more search clusters, wherein the one or more common terms associated with each search cluster comprise keywords common across the at least one content items of the search cluster;
determining, by the computing system, a plurality of related topics, wherein the plurality of related topics comprise a set of related topics for each search cluster in the one or more search clusters, wherein the set of related topics associated with each search cluster is based on the one or more common terms associated with the search cluster;
selecting, by the computing system, one or more search related topics from the plurality of related topics;
determining, by the computing system, supplemental search criteria for each search related topic in the one or more search related topics;
identifying, by the computing system, a set of topic search results for each search related topic based on the search query and the supplemental search criteria for the search related topic;
generating, by the computing system, supplemental information associated with the search query, wherein the supplemental information comprises the one or more search related topics and a topic link for each of the one or more search related topics, wherein the topic link for each search related topic directs a user to the set of topic search results associated with the search related topic;
identifying, by the computing system, one or more news categories associated with the search query, wherein the one or more news categories are predefined news categories, and wherein the one or more news categories are at least one of world news, US news, or sports news; and
providing, by the computing system, the set of search results, the one or more news categories, and the supplemental information for display simultaneously, wherein the set of search results is provided in a search results area, and the one or more news categories and the supplemental information are provided in a supplemental content area separate from the search results area.
2. The computer-implemented method of claim 1 , wherein the one or more news categories are provided for display with a category link associated with each news category in the one or more news categories, wherein the category link for each news category in the one or more news categories directs a user to one or more content items associated with the news category.
3. The computer-implemented method of claim 1 , wherein at least one of the one or more news categories comprise a section of a periodical associated with the search query.
4. The computer-implemented method of claim 1 , wherein selecting one or more search related topics from the plurality of related topics comprises:
determining, by the computing system, a ranking for each related topic in the plurality of related topics; and
selecting, by the computing system, the one or more search related topics based at least in part on the ranking for each related topic in the plurality of related topics.
5. The computer-implemented method of claim 4 , wherein the ranking for a respective related topic in the plurality of related topics is determined based on at least one of a popularity, a relevance, a frequency, or a recency associated with the respective related topic.
