Embodiment 1

[0047] In Embodiment 1, assume that the sample information is such a piece of text "AV interface is an interface that appeared relatively early, and it is composed of red, white, and yellow lines, wherein the yellow line is the video transmission line, and the red and white lines are It is responsible for the sound transmission of the left and right channels. The appearance of the AV interface separates and transmits video and audio for the first time, but there is only one line responsible for video transmission, so this transmission method still mixes brightness and chroma first, and then displays it on the display device. Therefore, there is still some loss in video transmission quality. The AV interface was once widely used in the connection between early VCD and DVD players and TV sets.”

[0048] Then, if it is assumed that "AV" is a keyword in the text filtering rule in the information filtering mechanism adopted by the information filtering server 21, then since there ar...

Embodiment 2

[0074] Embodiment 2 adopts such as Figure 3a The shown system implements the solutions provided by the embodiments of the present invention.

[0075] In Embodiment 2, it is assumed that the set of information to be filtered contains text information such as the character string "port AVAudio", and it is assumed that the filtering strategy adopted by the information filtering server is to filter information based on keywords, and the keywords used include " AV", then embodiment 2 adopts such as Figure 3b The following steps are shown to avoid misjudgment of the information to be filtered:

[0076] Step 31, the information filtering server filters the first set of information to be filtered according to the above filtering strategy, and outputs suspicious information to the positive feedback secondary filtering server;

[0077] Since the above-mentioned text information contains a character string such as "port AVAudio", and the keyword used by the information filtering serv...

Embodiment 3

[0104] Embodiment 3 still adopts such as Figure 3a The shown system implements the solutions provided by the embodiments of the present invention.

[0105] In Embodiment 3, the initial step is to generate a misjudgment information feature library based on the misjudgment information output by the manual review system, and introduce the solution provided by the embodiment of the present invention. Specifically, the implementation process of embodiment 3 includes such as Figure 4 The following steps are shown:

[0106] Step 41, extracting misjudgment information features from the misjudgment information output by the manual review system;

[0107] For example, assuming that the misjudgment information contains a picture of a female star, for the picture of the female star, the size ratio of the picture (such as the aspect ratio of the picture), the proportion of a certain color in the picture (such as the proportion of skin color), and the hue of the picture can be extracted...

Abstract

The invention discloses an information filtering system used for solving the problem that a large number of processing resources are consumed when the misjudgment rate is reduced based on a manual review system in the prior art. The information filtering system comprises an information filtering server and a positive feedback secondary filtering server, wherein the information filtering server is used for filtering an information set to be filtered according to a preset information filtering mechanism and outputting a first information set composed of determined suspicious information; the positive feedback secondary filtering server is used for obtaining the first information set output by the information filtering server, and respectively judging whether each piece of information in the first information set is matched with misjudged information characteristics according to a preset misjudged information characteristic library; the information matched with the misjudged information characteristics is released; the misjudged information characteristics are extracted from misjudged information which is misjudged as the suspicious information. The invention further discloses an information filtering method and device.

Description

technical field [0001] The invention relates to the field of data services, in particular to an information filtering method, system and device. Background technique [0002] Information filtering is an important technology of the Internet, and its processing objects are generally information transmitted in web pages and data services (such as text information, picture information, audio information and video information based on BitTorrent), short messages, multimedia messages and ring tones, etc. [0003] Since the information to be filtered generally does not have the characteristics of multiple complete repetitions, information filtering generally adopts a feature-based identification method. Taking text information in data services as an example, the feature-based approach mainly refers to filtering text information based on some keywords. The defect of this method is that since some legal information may also contain specified keywords, this method will misjudge legal...
