The invention provides a user data classification method and system. The user data classification method comprises the steps of obtaining a user text set and a keyword library; determining hit vocabularies in a user text through keywords in the keyword library, and obtaining codes of the hit vocabularies; determining a feature matrix through the codes of the hit vocabularies; inputting the feature matrix corresponding to each user text into a neural network for training to obtain a classification model; and inputting a to-be-processed user text into the classification model to obtain a classification label. According to the scheme, the keywords are determined in the mode of presetting the keyword library, then the hit vocabularies in the user text are determined, the corresponding relation among the user text, the hit vocabularies and the classification labels is established through training and learning of the neural network, then the user text to be processed is classified through the classification model, and the classification accuracy and efficiency are improved.
Description
technical field [0001] The invention relates to the technical field of natural language processing, in particular to a user data classification method and system. Background technique [0002] With the continuous development of society and economy, the needs of users tend to be refined and subdivided. However, users are limited by their own knowledge structure and professional knowledge, and often cannot make a clear classification of their own needs. As a result, there is a mismatch between the actual needs of users and the selected support services. At present, manual classification is carried out through user self-reports. On the one hand, user self-reports are often not accurate enough; on the other hand, manual classification is inefficient. Contents of the invention [0003] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a method and system for classifying user data to solve the problem of inconvenient...
