Abstract
Text classification is an important research direction in the field of natural language processing. With the development of Internet, the use of e-mail is becoming more and more common. It is very important to quickly understand the subject and content of an e-mail in a mailbox. For example, when the police handle a case and face this demand, the intelligent processing of text information by computer has been extensively studied. This paper proposes an application of mail classification based on LDA topic model, which combines information extraction, information retrieval and natural language processing. SVM classifier is used, and TF-IDF technology, which is a technical evaluation method for the classification of this application, is also proposed. It is believed that LDA has a certain effect in mail classification, and the uncertainty and subjectivity in LDA classification are also proposed.
