Abstract

Disclosed a method and system for providing search query suggestions to a user based on contextual information. The contextual information includes the user's earlier search queries and the user's current input (prefix) for a search query. Considering prefix enables narrowing down of a query candidate set used for suggesting search queries to the user.

Method and System for Providing Context Based Search Query Suggestions

Abstract

Disclosed a method and system for providing search query suggestions to a user based on contextual information.  The contextual information includes the user’s earlier search queries and the user’s current input (prefix) for a search query.  Considering prefix enables narrowing down of a query candidate set used for suggesting search queries to the user.

Description

A method and system is disclosed for providing search query suggestions to a user based on contextual information.  The contextual information includes the user’s earlier search queries and the user’s current input (prefix) for a search query.  Considering prefix enables narrowing down of a query candidate set used for suggesting search queries to the user.

Figure 1 illustrates a block diagram of the system for providing search query suggestions to a user based on contextual information.

The system includes a log process module for extracting one or more query pairs from previous queries and a new query from search logs.  Thereafter, a feature generation module generates one or more features from the one or more query pairs extracted by the log process module.  The one or more features include the following:

·      for a given previous query and a prefix, a traffic detail of each suggestion;

·      for a given previous query and a prefix, sum of all suggestion traffics;

·      for a given previous query and a prefix, a traffic proportion of each suggestion;

·      an overall traffic of each suggestion;

·      a suggestion length; and

·      an overall traffic of each previous query.

In accordance with the method and system disclosed herein, a pair generation module generates one or more pairs satisfying following conditions:

·      suggestion’s traffic is at least 3;

·      suggestion is searched at least 5%;

·      suggestion’s length is at least 3;

·      suggestion’s over all traffic is at least 10; and

·      previous query’s overall traffic/suggestion’s overall traffic <= 10000.

The thresholds and rules are configurable and can be changed based on an appli...
