Abstract
Methods and apparatus disclosed include identifying a pair comprising a document visited and a subsequent query, the subsequent query being submitted after visiting the document visited; generating a feature representation for the pair, each of the feature representations including one or more document features representing the content of a document visited, and one or more query features representing the content of a subsequent query; embedding the document features and the query features in a reduced dimensionality space; and determining a similarity measure for the reduced dimensionality space. In some embodiments, the similarity measure is indicative of the likelihood of co-occurrence of the document visited and the subsequent query. Other embodiments include iteratively training a query suggestion rule, applying the query suggestion rule to provide suggested queries in response to a document visited, corresponding systems, apparatus, and computer program products.
