Abstract
A method and system for generating a replacement query for a user-entered query is provided. The user-entered query is received by a service that never used it and is potentially erroneously entered. The method comprises selecting a set of queries for the user-entered query from past queries based on string similarity. The method comprises retrieving past-query-interdependence data indicative of past transitions between each pair of queries in the set of queries. The method comprises selecting an approximated query from the set of queries based on string similarity and usage frequency. The method comprises, for each pair of approximated query and one of the set of queries, generating a vector based on past-query-interdependence data between the approximated query and respective one of the set of queries. Each vector can be used as an approximated vector. The method comprises generating ranking parameters for the approximated vectors and determining the replacement query.
