Query suggestion for e-commerce sites
First Claim
1. A method for providing query suggestions for a user comprising:
- receiving a low frequency query from a client machine;
analyzing a query log of user query sessions to identify a plurality of ordered sequences of low frequency queries including the low frequency query;
generating a set of transition scores for the plurality of ordered sequences of low frequency queries based at least in part on a maximum number of transitions between a first query of an ordered pair of the plurality of ordered sequences of low frequency queries and a second query of the pair to a purchase-related event, wherein an individual transition score comprises an accumulation of a popularity score and an accumulation of a purchase efficiency score;
determining a normalized set of transition scores based on a frequency of the first query of each of the plurality of ordered sequences of low frequency queries;
building a set of query suggestions for the low frequency query from the normalized set of transition scores;
computing a set of similarity metrics for members of the set of query suggestions;
determining whether one or more similarity metrics for individual suggestions of the set of query suggestions meet a predetermined similarity; and
providing to the client machine a list of the individual suggestions whose similarity metrics meet the predetermined similarity.

Abstract
Query suggestions are provided using a query log including a number of user sessions that comprise training data. The training data includes a sequence of a plurality of sets of queries, some of the sets of queries including query transitions followed by a purchase related event. From a cleaned and normalized query log stationary scores and transition scores of at least some of the plurality of sets are generated. A set of query suggestions is built and similarity scores are computed for at least some of the set of query suggestions to determine whether individual ones of the at least some of the set of query suggestions meet a predetermined assurance level. Those that meet the assurance level are included as elements of the set of query suggestions. The set of query suggestions is mixed and ranked according to a user behavior that is sought to be influenced.
