Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for evaluating substitute terms. One of the methods includes selecting a first term and a candidate substitute term for the first term. A first vector is generated for the first term using co-occurrence frequencies of terms that occur in search queries that include the first term. A second vector is generated for the candidate substitute term using co-occurrence frequencies of terms that occur in search queries that include the candidate substitute term. The first vector and the second vector are compared to score an association between the first term and the candidate substitute term.
