[0018] Overview

[0019] This summary describes the integration of time and location information associated with query input in order to improve mobile query suggestions. For example, a time-location awareness (TLA) application can operate as a mobile search engine to provide relevant query suggestions, which are recommendations for users to perform further searches. Typical methods for measuring the distance between similar queries include: using keywords or query phrases, matching keywords between queries, associating uniform resource locators (URLs) that are usually clicked with queries, or calculating and query associations The similarity between the clicked documents. The TLA application also categorizes these methods into two types, namely content-based methods and link-based metrics. Content-based methods suggest queries based on string matching or semantic similarity. Link-based metrics suggest related queries by exploring links between query nodes, regardless of the c...

Abstract

The invention disclose a mobile query suggestions with time-location awareness. The techniques describe recommending mobile query suggestions by integrating time and location in response to a query input submitted on a mobile computing device. A process constructs a bipartite graph by extracting users that submitted queries from mobile search logs and associating time and location with the submitted queries. The process determines the users are similar having submitted similar queries at similar times and at similar locations. The process receives a query input associated with a current time and a current location of a mobile computing device. Next, the process computes a relatedness of candidate queries to the query input based on a similarity between the user groups having submitted both the candidate queries and the query input, and distances of times and locations at which the user previously issued the query input and the candidate queries.

Description

Technical field [0001] The present invention relates to a technology for recommending mobile query suggestions by integrating time and location. Background technique [0002] Search engine companies provide users with convenient search services, such as personal computer (PC) web search. Recently, search engine companies are implementing mobile search engine applications for mobile computing devices. Mobile search differs from PC web search in several ways. One difference is that for mobile search queries, users tend to type shorter text inputs, because entering text on mobile computing devices is often difficult or awkward. Another difference is that users who perform mobile searches generally prefer that the search results returned are related to the query time and / or the user's current location. Another difference is that the results of mobile search queries are limited because mobile computing devices have less bandwidth than PCs and much smaller screens to display informa...
