Legal consultations refer to the activities of persons engaged in legal services to explain and explain about legal affairs problems and propose suggestions and solutions. The user portrait is also called a user role, and is an effective tool for delineating target users and connecting user appeal and design direction. Each concrete information of the user is abstracted into labels, and the user image is concretized by using the labels, so that the targeted service is provided for the user. Because the legal system is too huge and complicated, the case sources involved in legal consultation are too wide, and along with the development of intelligent interaction technology, more and more intelligent legal robots are applied to the legal consultation.
In the prior art, a judgment document data set is pre-labeled on the basis of a mass machine, a neural network model is introduced to provide an interactive mode of spoken question-answer legal questions for a user, and a customized advisory report generated on the basis of continuously added legal texts is provided for the user through a natural text information extraction technology.
However, it is difficult for the client to ensure that the language completely fits the legal consultation subject in the process of communicating with the legal robot, and especially for the client who does not know the legal terms, a large amount of complex non-professional statements are needed to express the case. The prior art analyzes according to the semantics in the recognized language interaction, and quickly matches the data of similar cases or searches out related laws and regulations according to keywords. However, the nonprofessional statement may bring a lot of noise information interference to the legal robot, and the legal robot can easily read out the case that does not fit the reality and make irrelevant responses under a lot of noise information, because the legal robot cannot acquire accurate client consultation intentions, the client cannot easily read out the responses of the target, so that communication barriers are generated between the human machine and the machine, and the user experience is poor. Therefore, the prior art also has the problem of poor user experience in the legal consultation interaction process.
