Abstract

The invention provides a junk short message detecting method and device, relates to the field of information processing, and aims at improving the accuracy and efficiency of junk short message detection. The method comprises that a training sample flow of a present training time window is obtained according to a last short message time window; feature information is extracted from the training sample flow of the present training time window, comprises a short message sending feature and a short message content feature, and includes at least one feature parameter; the training sample flow in the present training time window is trained and classified on the basis of the feature information, and values of the at least one feature parameter corresponding to a normal short message and a junk short message are obtained; and on the basis of the values of the at least one feature parameter, a short message flow in a present short message time window is classified and determined, and the junk short message of the short message flow in the present short message time window is determined.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a spam short message detection method and device. Background technique [0002] With the rapid development of communication technology, the use of mobile phones is becoming more and more extensive.
