Abstract

The invention provides a comment spam recognition method and device. The comment spam recognition method includes: constructing a language model for a comment according to a participle of the comment read from a comment set, and acquiring the probability of the comment; calculating the similarity between the two comments according to the probability of the comment and the probability of the other comment in the comment set; and determining that the two comments are untruthful comments when the similarity satisfies a similarity demand. The technical scheme can effectively recognize the untruthful comments, and can protect the integrity and the authenticity of use feedback data.
