Abstract:
1. A computer-implemented method comprising: determining, by operation of a system, a first search results score associated with first search results that were generated for an original search query that includes a first query term, wherein the first search results score is based on (i) a respective rank of each first search result, and (ii) a respective first popularity score associated with each first search result; revising the search query to include a second query term; determining a second search results score associated with second search results that were generated for the revised search query, wherein the second search results score is based on (i) a respective rank of each second search result, and (ii) a respective second popularity score associated with each second search result; determining that a difference between the first search results score and the second search results score satisfies a specified threshold; and determining that, for the original search query, the second query term is a substitute for the first query term based on determining that the difference between the first search results score and the second search results score satisfies the specified threshold.
