Abstract

The invention discloses a short message filtering method based on user creditworthiness and short message spam degree. The short message filtering method includes the following steps: a step A is that initial creditworthiness is given to each short message service user according to active conditions of the short message service user; a step B is text preprocessing, wherein normal punctuations are eliminated first, disturbing characters set by a system are identified, the number of the disturbing characters is recorded, the disturbing characters are eliminated, and digits with specific codes and pictographic codes are used for replacing the disturbing characters; a step C is that a cell phone number and a uniform resource locator (URL) address are extracted, and correlation behavior features of a short message are extracted; a step D is that the essential attribute of the spam degree is newly added to a keyword, the keyword is matched based on contents which are obtained after the text preprocessing in the step B, and all matched keywords are recorded; a step E is that similar contents are defined, and the short message spam degree is calculated based on the similarity; and a step F is that whether interception is conducted is judged by combination of the user creditworthiness and the short message spam degree. Due to the fact that the short message filtering method is based on the user creditworthiness and the short message spam degree, filtering of spam short messages can be realized more accurately, and misjudgments of the spam short messages can be reduced.
