Abstract:
1. A computer-implemented method, comprising: receiving a query and a current version of a document; receiving quality of result data for a plurality of versions of the document and the query, the quality of result data specifying a respective version-specific quality of result statistic for each of the versions of the document with respect to the query; calculating a weight for the version-specific quality of result statistics corresponding to each version of the document, wherein the weight for a particular version of the document is determined at least in part on an estimate of a difference between the particular version and the current version of the document, and wherein calculating the weight for a particular version of the document comprises: determining a weighted overall quality of result statistic for the document with respect to the query, wherein determining the weighted overall quality of result statistic comprises weighting each version-specific quality of result statistic with the calculated weight and combining the weighted version-specific quality of result statistics; and associating the weighted overall quality of result statistic with the document.
