Abstract

The invention discloses a method and a device for classification of mails. The method for the classification of the mails includes the steps: enabling the mails to be classified to be through text segmentation to get an entry set; matching entries in the entry set with feature words which represents categories of the mails in a feature word bank, and calculating conditional probability of the categories which the mails belong to according to a matching result; and confirming the categories of the mails according to the conditional probability. The method for the classification of the mails resolves the problems that in the prior art, the method for classification of the mails is less in quantity and low in accuracy, accordingly the effects of high-efficiency accurate classification of the mails and filtering of junk mails are achieved, and performance of a system is improved and user experience is also improved.
