Methods, systems, and media for providing a media search engine

Abstract

Methods, systems, and media for providing a media search engine are provided. In some implementations, a method for searching for content is provided, the method comprising: receiving a media search query for media assets; identifying web search results from a corpus of web resources that are responsive to the media search query, wherein each of the web search results has an associated relevancy score; determining keyword information and contextual information from a subset of the web search results, wherein the subset of the web search results is selected from the web search results based on the associated relevancy score and wherein media entities are determined from at least a portion of the keyword information and the contextual information; assigning a topic score for the each of the media entities based on occurrence in the web search results; selecting at least one media entity from the media entities based on the topic score; identifying media assets from a corpus of media assets based at least in part on the selected media entity; and causing a subset of the media assets to be presented to a user in response to the media search query.

What is claimed is: 
     
         1 . A system for searching for content, the system comprising:
 a hardware processor that:
 receives a query for one or more media assets; 
 determines entity information from at least a portion of keyword information that is determined from at least a portion of search results responsive to the query, wherein an entity is selected from the entity information based on occurrence of the entity in the search results; and 
 causes a media asset corresponding to the selected entity to be presented in response to the query. 
   
     
     
         2 . The system of  claim 1 , wherein the entity information includes media entity information. 
     
     
         3 . The system of  claim 1 , wherein the hardware processor further identifies the media asset based on the selected entity. 
     
     
         4 . The system of  claim 1 , wherein the hardware processor further identifies a plurality of search results from a corpus of web resources that are responsive to the query. 
     
     
         5 . The system of  claim 4 , wherein the hardware processor further rewrites the query by inserting one or more media terms prior to identifying the plurality of search results from the corpus of web resources. 
     
     
         6 . The system of  claim 1 , wherein the hardware processor further:
 assigns a topic score for the each of the entity information based on occurrence in the portion of search results; and   increments the topic score for an entity upon determining that a page corresponding to a search result relates to the entity, wherein the entity is selected from the entity information based on the topic score.   
     
     
         7 . The system of  claim 1 , wherein a plurality of media assets are identified based on the selected entity and wherein a subset of the plurality of media assets are presented in response to the query. 
     
     
         8 . The system of  claim 7 , wherein the hardware processor further:
 determines a quality score for each of the plurality of identified media assets; and   filters the at least a subset of the plurality of media assets based on the determined quality score.   
     
     
         9 . The system of  claim 1 , wherein the hardware processor further accesses an entity table that maps a web resource identifier corresponding to a web search result to an entity, wherein the web resource identifier comprises a link to a related website. 
     
     
         10 . A method for searching for content, the method comprising:
 receiving, using a hardware processor, a query for one or more media assets;   determining, using the hardware processor, entity information from at least a portion of keyword information that is determined from at least a portion of search results responsive to the query, wherein an entity is selected from the entity information based on occurrence of the entity in the search results; and   causing, using the hardware processor, a media asset corresponding to the selected entity to be presented in response to the query.   
     
     
         11 . The method of  claim 10 , wherein the entity information includes media entity information. 
     
     
         12 . The method of  claim 10 , wherein the method further comprises identifying the media asset based on the selected entity. 
     
     
         13 . The system of  claim 10 , wherein the method further comprises identifying a plurality of search results from a corpus of web resources that are responsive to the query. 
     
     
         14 . The system of  claim 13 , wherein the method further comprises rewriting the query by inserting one or more media terms prior to identifying the plurality of search results from the corpus of web resources. 
     
     
         15 . The system of  claim 10 , wherein the method further comprises:
 assigning a topic score for the each of the entity information based on occurrence in the portion of search results; and   incrementing the topic score for an entity upon determining that a page corresponding to a search result relates to the entity, wherein the entity is selected from the entity information based on the topic score.   
     
     
         16 . The system of  claim 10 , wherein a plurality of media assets are identified based on the selected entity and wherein a subset of the plurality of media assets are presented in response to the query. 
     
     
         17 . The system of  claim 16 , wherein the method further comprises:
 determining a quality score for each of the plurality of identified media assets; and   filtering the at least a subset of the plurality of media assets based on the determined quality score.   
     
     
         18 . The system of  claim 10 , wherein the method further comprises accessing an entity table that maps a web resource identifier corresponding to a web search result to an entity, wherein the web resource identifier comprises a link to a related website. 
     
     
         19 . A non-transitory computer-readable medium containing computer-executable instructions that, when executed by a processor, cause the processor to perform a method for searching for content, the method comprising:
 receiving a query for one or more media assets;   determining entity information from at least a portion of keyword information that is determined from at least a portion of search results responsive to the query, wherein an entity is selected from the entity information based on occurrence of the entity in the search results; and   causing a media asset corresponding to the selected entity to be presented in response to the query.
