Domain expert search
First Claim
1. A method for identifying an expert information source, the method comprising:
- analyzing first search results obtained by a search system, the first search results including search results for at least one query associated with more than one category included in a query ontology;
based on the analysis of the first search results, determining a relative contribution by an information source to the first search results;
analyzing second search results, obtained by the search system, for queries associated with a particular category included in the query ontology, the second search results being different but not exclusive of the first search results;
based on the analysis of the second search results, determining a relative contribution by the information source to the second search results;
comparing the relative contribution by the information source to the first search results to the relative contribution by the information source to the second search results;
based on comparison results, determining whether the relative contribution by the information source to the second search results is more than a threshold greater than the relative contribution by the information source to the first search results; and
in response to determining that the relative contribution by the information source to the second search results is more than the threshold greater than the relative contribution by the information source to the first search results;
identifying the information source as an expert information source for the particular category included in the query ontology; and
storing, in electronic storage, data indicating that the information source is an expert information source for the particular category included in the query ontology.

Abstract
Expert domains for a query category represent domains from which a high percentage of search results for queries associated with the query category are retrieved. The expert domains are identified by establishing a base statistical model that indicates frequencies of appearance for domains in search results retrieved for queries corresponding to multiple categories. In addition, frequencies of domain appearance are determined for search results retrieved for queries associated with a category. Domains that appear more frequently in the search results corresponding to the category are identified as expert domains for the category. A user may be allowed to customize expert domains related to one or more categories by adding or removing expert domains for the category.

8. A system for identifying an expert information source, the system comprising:
-
an electronic data store configured to store information defining a query ontology; and at least one processor configured to perform operations comprising; analyzing first search results, the first search results including search results for at least one query associated with more than one category included in the query ontology; based on the analysis of the first search results, determining a relative contribution by an information source to the first search results, analyzing second search results for queries associated with a particular category included in the query ontology, the second search results being different but not exclusive of the first search results; based on the analysis of the second search results, determining a relative contribution by the information source to the second search results; comparing the relative contribution by the information source to the first search results to the relative contribution by the information source to the second search results; based on comparison results, determining whether the relative contribution by the information source to the second search results is more than a threshold greater than the relative contribution by the information source to the first search results; and in response to determining that, the relative contribution by the information source to the second search results is more than the threshold greater than the relative contribution by the information source to the first search results; identifying the information source as an expert information source for the particular category included in the query ontology; and storing, in the electronic data store, data indicating that the information source is an expert information source for the particular category included in the query ontology.
