11. A system, comprising: means for determining whether prior query data and prior category data associated with prior search results comprise category synonyms, where the prior query data includes at least: query terms associated with a user query for business listing information, a resulting business name returned in response to the user query, and a resulting business category associated with the resulting business name; where the means for determining includes: means for determining whether the prior query data relates to a name query or a categorical query, means for determining whether the query terms are a candidate synonym of the resulting business category when the prior query data relates to a categorical query, means for determining whether a query, category pair, associated with the prior query data, is a hyponym, means for rejecting the query terms as a synonym of the resulting business category when the query, category pair, associated with the prior query data, is a hyponym, and means for accepting the query terms as a synonym of the resulting business category when the query, category pair, associated with the prior query data, is not a hyponym; means for receiving a subsequent search request relating to the prior category data; means for refining the subsequent search request based on the prior query data when the prior query data and the prior category data comprise category synonyms; means for performing a search based on the refined search request; and means for providing search results based on the search.

The system of claim 11 , wherein the means for determining whether prior query data and prior category data associated with prior search results comprise category synonyms further comprises: means for determining whether the prior search results are good search results; and means for determining whether the prior query data and the prior category data included within the prior search results comprise category synonyms when the prior search results are determined to be good search results.
