Japanese Patent JP7137705
Kind Code:
B2
Abstract:
The present application discloses a method for building a ranking model, a query auto-completion method and corresponding apparatuses, which relates to the technical field of intelligent search. An implementation includes: acquiring from a POI query log a query prefix input when a user selects a POI from query completion suggestions, POIs in the query completion suggestions corresponding to the query prefix and the POI selected by the user in the query completion suggestions; constructing positive and negative example pairs using the POI selected by the user and the POIs not selected by the user in the query completion suggestions corresponding to the same query prefix; and performing a training operation using the query prefix and the positive and negative example pairs corresponding to the query prefix to obtain the ranking model; wherein the ranking model has a training target of maximizing the difference between the similarity of vector representation of the query prefix and vector representation of the corresponding positive example POI and the similarity of the vector representation of the query prefix and vector representation of the corresponding negative example POIs.
