Problems solved by technology

On the one hand, when manually annotating the training corpus, it is impossible to distinguish the real intentions of users in many questions, resulting in different annotation results by different people, thus affecting the quality of training data
On the other hand, the trained model will always have the same prediction intention for the same words, and will not change according to different contexts, resulting in prediction errors

Abstract

The invention discloses a method and system for intention recognition based on a context. The method comprises the steps of carrying out manual annotation on problems provided by a user and included in a user historical consulting log on the basis of the user historical consulting log; extracting features of each problem to generate a training corpus; carrying out model training on the generated training corpuses according to a supervised learning algorithm to obtain a training model; estimating the current problems and obtaining an estimated user intention recognition result on the basis of the obtained training model.

Description

technical field [0001] The present invention relates to the field of artificial intelligence, in particular to a method and system for recognizing intentions based on context. Background technique [0002] Intent recognition is the recognition of the intent of a behavior. For example, in a question-and-answer dialogue, each sentence of the questioner has a certain intention, and the respondent responds according to the intention of the other party. [0003] Related questions are widely used in search engines, chat robots and other scenarios. Especially in chatbots, intent recognition is the core module of the entire system. When answering the user's question, it is to analyze the user's intention and give the corresponding answer after understanding what the user wants to ask. [0004] The method of intent recognition in the prior art is mainly to obtain a batch of data, and then manually mark the intent of each piece of data, so as to obtain training data. The model is ...
