Filtering method and device for network malicious information

Abstract

The invention discloses a filtering method and device for network malicious information and relates to the technical field of computer information processing and information filtering. The filtering method disclosed by the embodiment of the invention comprises the following steps of: obtaining text information to be filtered, system pre-research model information and user feedback model information; pre-treating the text information to be filtered; carrying out characteristic information matching on the pre-treated text information to be filtered and the system pre-research model information to obtain a first matched result; carrying out the characteristic information matching on the pre-treated text information to be filtered and user feedback model information to obtain a second matched result; and carrying out filtering treatment on the text information to be filtered according to the first matched result and the second matched result. With the adoption of the filtering method and device of the network malicious information, disclosed by the embodiment of the invention, the automatic filtering performance for the malicious information is improved and system information can be automatically updated.

Description

technical field [0001] The invention relates to the technical field of computer information processing and information filtering, in particular to a method and device for filtering bad network information based on statistics and rules. Background technique [0002] With the rapid development of the Internet, the speed of information dissemination has also accelerated. Because the content on the Internet is mixed, such as advertisements, pornography, violence, and reactionary bad information are difficult to eliminate, and gradually spread in a more covert way, so it is very important to suppress the spread of bad information and purify the Internet space. important. For the massive amount of data information on the Internet, if artificial methods are used to filter bad information on the Internet, it will take a huge amount of manpower and material resources. Therefore, the automatic filtering technology of bad information based on Internet content has become a research ho...

AI Technical Summary

Problems solved by technology

[0007] (2) The content of bad information has great variability and concealment

[0008] (3) User dictionaries only provide exact keyword matching methods, resulting in mechanical and inflexible judgment methods

[0009] (4) Some traditional Chinese information processing practices are not suitable for bad information filtering based on text classification

[0010] (5) Lack of a unified model to comprehensively filter bad information including advertising, pornography, violence, reactionary, etc.

[0011] In the process of realizing the above-mentioned automatic filtering technology of bad information based on Internet content, the inventor found that in the prior art, the performance of automatic filtering of bad information cannot meet the filtering requirements of the current Internet, and automatic update cannot be realized
