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.
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. 14. The method of claim 11 wherein the performance impact comprises a new performance evaluation of the search engine performing a search using the pending query-to-as set mappings relative to a previous performance evaluation of the search engine associated with the approved query-to-asset mappings, wherein if the new performance evaluation is negative relative to the previous performance evaluation, the method further comprises: generating a list of query-to-asset mappings, wherein one or more query-to-asset mappings are marked for removal based on the determined performance impact.
