Embodiment 1

[0043] Please refer to figure 1 , the embodiment of the present application provides a method for detecting similar text messages, the method includes

[0044] S11: Segment the target text message, and obtain the target word vector of the target text message according to each word segment and the corpus word matrix;

[0045] S12: Obtain the similarity between the target word vector and the set word vector, wherein the set word vector is the word vector of at least one or at least one type of reference short message;

[0046] S13: judging whether the similarity is greater than a set threshold;

[0047] S14: If the similarity is greater than the set threshold, determine that the target short message is similar to the at least one or at least one type of reference short message.

[0048] When executing S11 to segment the target short message, all the received short messages can be used as target short messages for word segmentation, or the received short messages can be firstly...

Embodiment 2

[0077] Please refer to image 3 , the embodiment of the present application provides a method for detecting similar short messages in accordance with Embodiment 1, and accordingly provides a device for detecting similar short messages, which includes:

[0078] Word vector acquisition module 31, is used for carrying out word segmentation to target note, and obtains the target word vector of described target note according to each word segmentation and corpus word matrix;

[0079] The similarity calculation module 32 is used to obtain the similarity between the target word vector and the set word vector, wherein the set word vector is the word vector of at least one or at least one type of reference message;

[0080] A judging module 33, configured to judge whether the similarity is greater than a set threshold;

[0081] The first confirming module 34 is configured to determine that the target short message is similar to the at least one or at least one type of reference short ...

Abstract

The invention discloses a method and an apparatus for detecting similar short messages. The method comprises the following steps of: performing word segmentation for a target short message, and obtaining a target word vector of the target short message according to each segmented word and corpus word matrix; obtaining similarity between the target word vector and a set word vector, wherein the set word vector is the word vector of at least one piece of or at least one type of reference short messages; judging whether the similarity is greater than a set threshold value; and if the similarity is greater than the set threshold value, determining that the target short message is similar to the at least one piece or at least one type of reference short messages. In the technical scheme above, the target short message and the reference short message are converted into word vectors, and similarity between the word vectors of the short message is calculated for obtaining the target short message similar to the reference short message, thus, a new short message is detected, then, a technical problem of lag in identification of the new short message in the prior art is solved, and identification efficiency for the new short message is improved.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method and device for detecting similar short messages. Background technique [0002] With the continuous development of science and technology, communication technology has developed rapidly, and there are various ways of communication, including telephone, short message, email and so on. [0003] Short messages are widely used by people because of their short and concise advantages, low cost, etc., and they are also used by lawbreakers because of their wide use and low cost. People often receive fraudulent text messages about stolen bank cards, flight cancellations, point redemption, etc. sent by criminals, and they will be defrauded by criminals if they are not careful. In order to reduce the chances of people being defrauded, the existing technology usually uses marking and screening methods to help users identify fraudulent text messages. The specific proce...
