Problems solved by technology

In the prior art, the user query intent is usually determined by matching the query information with the mined query intent template. In the above method, on the one hand, it takes a long time to mine the query intent template; The query intent template can not cover all user query intents, resulting in low template coverage. Therefore, how to improve the efficiency and accuracy of user query intent recognition is a problem worth considering.

Abstract

The invention discloses query intention mining and query intention recognition methods and devices, and belongs to the technical field of communication. The method comprises the steps of extracting all keywords in to-be-queried query information to obtain a plurality of keyword sets; based on a distribution probability between each keyword set obtained in advance and each large-class intention, calculating a distribution probability of the query information in each large-class intention, and determining a target large-type intention; and based on intention types of keywords in the target large-class intention, further determining sub-intentions of the query information. Therefore, the efficiency and accuracy of query intention recognition are improved, the query range of the query information is expanded, and the diversity of query results of the query information is improved.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a method and device for mining and identifying query intentions. Background technique [0002] This section is intended to provide a background or context to the implementations of the application that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] At present, when searching according to the query information input by the user, keywords can be extracted from the query information by word segmentation, and the search results can be returned by keyword matching. However, since the keywords extracted from the query information may exist Multiple ambiguities, therefore, the obtained search results may be far from the user's query intent. [0004] In order to identify the user's query intention and use it to search, so as to more accurately return the search results that best meet their ...
