11. A method for evaluating query-to-asset mappings comprising: authoring pending query-to-asset mappings for mapping queries in an information retrieval system to assets associated with one or more databases; evaluating with a computer processor performance of a classifier built from a combination of one or more different subsets of the pending query-to-asset mappings and approved query-to-asset mappings against performance of a second classifier built only from the approved query-to-asset mappings using a search evaluation tool to determine search result coverage and a performance impact on a search engine for each new query-to-asset mapping; marking, with the processor, one or more of the pending query-to-asset mappings or the approved query-to-asset mappings for removal based on the performance impact; and removing the marked query-to-asset mappings to obtain a modified set of query-to-asset mappings; wherein evaluating to determine coverage includes: uploading the classifier built from the combination of the approved query-to-asset mappings and the one or more different subsets of pending query-to-asset mappings to a test server coupled to the one or more databases for which the approved query-to-asset mappings and pending query-to-asset mappings are relevant; posting search queries to the test server; receiving search results from the test server responsive to the posted search queries; and verifying whether the pending query-to-asset mappings have a correct coverage by comparing the received search results against a set of expected results, wherein comparing the received search results against a set of expected results comprises: determining whether the received search results contain the set of expected results in a top-N positions of the received search results.

The method of claim 11 wherein the step of evaluating comprises: building a first runtime classifier based on the approved query-to-asset mappings; building a second runtime classifier based on a combination of the approved query-to-asset mappings and the pending query-to-asset mappings; and comparing the first runtime classifier and the second runtime classifier to identify differences.
