Problems solved by technology

[0004] Therefore, the content similarity between two texts is measured according to the cosine distance. Due to the symmetry of the cosine distance, the influence of the reference message selection is ignored. The actual measurement result should be asymmetric, the measurement result is inaccurate, and does not comply with network control. needs

Abstract

The invention discloses an internet forum message content similarity measuring method and system. In the method, the content similarity between test text message dk and reference text message d is calculated according to the test state vector Sk={s1k, s2k, ..., sMk} and the reference state vector S={s1, s2, ..., sM}. The content similarity between the test state vector Sk={s1k, s2k, ..., sMk} andthe reference state vector S={s1, s2, ..., sM} is not symmetrical, that is to say, the value of the content similarity between the two text messages is related to semantic features of the two text messages and also related to the selection of a reference message, the internet forum sensitive information control requirements are better met, and the measurement accuracy of the internet forum messagecontent similarity is improved.

Description

technical field [0001] The invention relates to the field of network public opinion management and control, in particular to a method and system for measuring content similarity of network forum messages. Background technique [0002] The method for measuring the similarity of text content in network forum messages in the prior art, the main technical idea is to establish a vector space model of the text to describe the content characteristics of the text, and measure the content by calculating the cosine distance between two text feature vectors similarity. [0003] In the prior art, the method for measuring the similarity of content by calculating the cosine distance between two text feature vectors is mainly characterized in that the cosine distance is symmetric, for example, there are two contents of text message A and text message B, and the text The content of message A is C A , the content of text message B is C B , when taking text message A as the benchmark, th...
