Abstract

The invention discloses a model training method and device and a recognition method and device of a statement service type. The model training method comprises the steps of collecting multiple piece of text information of each service type in multiple service types, and marking the service type which each statement in the collected text information belongs to so as to obtain a first training set; determining a statement vector corresponding to each statement in the first training set, wherein the statement vector is a multi-dimensional array used for solely representing the corresponding statement; utilizing a support vector machine to train a statement vector corresponding to the statement of each service type in the multiple service types to obtain a training model of the support vector machine corresponding to each service type, wherein the training model of the support vector machine is used for recognizing the service type of the statement. According to the model training method and device and the recognition method and device of the statement service type, the technical problem in the prior art that the service type recognition of the statement is low in accuracy is solved.

Description

technical field [0001] The present application relates to the field of text processing, in particular, to a model training method and device, and a sentence business type recognition method and device. Background technique [0002] At present, the computer system can identify the question that the user consults, and determine the type of business that the user wants to consult. The type of business refers to the type of business provided by the computer system. After the computer system recognizes the type of service that the user inquires, it will search for relevant information to reply to the user. For example, when the user inquires online "How to get to the Forbidden City?" Processes, such as calling maps, etc.; and when a user inquires about "how much is a ticket to the Forbidden City", the computer system should reply with travel business information. [0003] For the identification of the business type consulted by users, at present, it is mainly to identify the tex...
