Embodiment Construction

[0028] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] The core idea of ​​the present invention is: the user selects representative information as a spam sample, and defines the keywords of the spam, calculates the sample in the system to obtain a keyword score, and then the system uses the keyword score to perform The filter index value is obtained by simulation, and by comparing with the evaluation index, the keyword or keyword score can be continuously adjusted and optimized, and finally a reasonable spam keyword and keyword score can be obtained.

[0030] The spam information is information with similar characteristics, such as malicious mass advertisements, engaging in some illegal activities or selling illegal products, and some characteristics customized by users accordin...

Abstract

The invention is in use for solving the issue of unreasonable predefined garbage info. The invention includes steps: predefining key words of garbage info in sampled data; calculating point value corresponding to each key word; using the said point value of key word simulates the data of filtered sample so as to obtain filtered index value (FIV); determining whether the filtered index value is accorded with evaluating index; if not, adjusting key word or point value of key word, then simulating and calculating FIV; if yes, then ending adjustment. The invention can help user to determine key words and point values of key words of garbage info reasonably, and determine whether the received info is garbage info based on key words and point values of key words so as to raise effect for filtering info. The invention is applicable to different applications and systems widely such as feedback system, system for leaving word, forum, and task for treating garbage mail.
