Query intention mining and query intention recognition methods and devices

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. 本申请公开了种查询意图的挖掘和查询意图的识别方法、装置，属于通信技术领域，该方法包括，提取待查询的查询信息中的各个关键词，获得多个关键词集合，基于预先获取的各个关键词集合与每个大类意图之间的分布概率，计算查询信息在每个大类意图中的分布概率，进而确定目标大类意图，以及基
