Rich results relevant to user search queries
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for triggering rich results in response to queries. In one aspect, a method includes receiving a query. One or more search results are obtained from a first corpus. A rich result is triggered based on a score of the first-ranked search result if it meets a threshold relative to other search results. The rich result is populated with additional metadata about the first-ranked search result obtained from a second corpus. The rich result is provided in response to the query.
1. A computer-implemented method comprising:
receiving a query requesting a search of a first corpus of resources;
obtaining first search results responsive to the query from the first corpus of resources, the first search results including a first-ranked result;
determining whether a score for the first-ranked result satisfies a threshold, the threshold being determined based on a respective score of at least one of the remaining results in the first search results; and
responsive to the score satisfying the threshold:
searching a second corpus of resources using data associated, in the first corpus, with the first-ranked result to obtain, from the second corpus, one or more resources that refer to the first-ranked result,
generating a rich result for the first-ranked result, where the rich result comprises data from the first-ranked result and data obtained from the one or more resources in the second corpus, and
providing the rich result as a response to the query the rich result enhancing the first-ranked result in the first search results.
2. The method of claim 1 , wherein the score for the first-ranked result satisfies the threshold if the score is at least a threshold multiple of a score for a second-ranked search result in the first search results.
3. The method of claim 1 , wherein the score for the first-ranked result satisfies the threshold if the score is at least a threshold multiple of a score for a third-ranked search result or a fourth-ranked search result in the first search results.
4. The method of claim 1 , wherein the first corpus is a book corpus and the second corpus is a web-based corpus.
5. The method of claim 1 , wherein the second corpus includes news referring to the first-ranked result.
6. The method of claim 1 , wherein responsive to determining that the second corpus does not include one or more additional resources, providing the first search results for presentation to a query requestor.
7. The method of claim 1 , further comprising:
responsive to the score failing to satisfy the threshold, providing the first search results.
8. The method of claim 1 , wherein the rich result is provided with the first search results.
9. The method of claim 1 , wherein generating a rich result comprises correcting data from the first corpus of resources using data from the second corpus of resources.
10. The method of claim 9 , wherein correcting data from the first corpus of resources comprises:
comparing the data from the first corpus of resources with one or more variants of the data from the second corpus of resources; and
selecting the most popular variant for the rich result.
11. The method of claim 1 , wherein the rich result further comprises a snippet from the second corpus of resources.
12. A system comprising:
at least one processor; and
a memory storing instructions that, when executed by the at least one processor, cause the system to perform operations including:
receiving a query requesting a search of a first corpus,
obtaining search results responsive to the query from the first corpus, the search results including a first-ranked search result,
determining whether a score for the first-ranked search result satisfies a threshold, the threshold being determined based on a respective score of at least one of the remaining results in the search results, and
responsive to the score satisfying the threshold:
searching a second corpus using data associated, in the first corpus, with the first-ranked search result to obtain, from the second corpus, one or more resources that refer to the first-ranked search result,
generating a rich result for the first-ranked search result, where the rich result comprises data from the first-ranked search result and data obtained from content of the one or more resources, and
providing the rich result as a response to the query, the rich result enhancing the first-ranked search result.
13. The system of claim 12 , wherein the first corpus is a book corpus and the second corpus is a web-based corpus.
14. The system of claim 12 , wherein the second corpus includes news referring to the first-ranked search result.
15. The system of claim 12 , wherein responsive to determining that the second corpus fails to include one or more resources referring to the first-ranked search result, providing the search results from the first corpus for presentation to a query requestor.
16. The system of claim 12 , further comprising:
responsive to the score failing to satisfy the threshold, providing the search results from the first corpus.
17. The system of claim 12 , wherein the rich result is provided with the search results from the first corpus.
18. The system of claim 12 , wherein generating a rich result comprises correcting data from the first corpus using data from the second corpus.
19. A non-transitory, computer-readable medium storing instructions that, when executed by at least one processor, causes a computer system to perform operations comprising:
receiving a query requesting a search of a first corpus;
obtaining search results responsive to the query from the first corpus, the search results including a first-ranked search result;
determining whether a score for the first-ranked search result satisfies a threshold, the threshold being determined based on a respective score of at least one of the remaining results in the search results; and
responsive to the score satisfying the threshold:
searching a second corpus using data associated, in the first corpus, with the first-ranked search result to obtain, from the second corpus, one or more resources that refer to the first-ranked search result,
generating a rich result for the first-ranked search result, where the rich result comprises data from the first-ranked search result and data obtained from content of the one or more resources, and
providing the rich result as a response to the query, the rich result enhancing the first-ranked search result.
