Embodiment 1

[0047] The flow of the method in Embodiment 1 is shown in FIG. 1 . Before executing the process shown in FIG. 1 , it is necessary to set up a spam contact information database to store spam contact information. The spam contact information in the spam contact information database can be pre-configured into the spam contact information database by the chat room administrator by observing the information sent in the chat room, and add new information to the spam contact information database during the continuous work of the chat room. Spam contacts.

[0048] The process shown in Figure 1 is specifically:

[0049] Step 101: the chat system receives the information to be sent to the chat room;

[0050] In the present invention, the information described in step 101 is referred to as information to be sent.

[0051] Step 102: the chat system judges whether the currently received message to be sent carries the contact information, if so, executes step 103; otherwise, executes ste...

Embodiment 2

[0068] The difference between the information filtering method described in this embodiment and the information filtering method described in Embodiment 1 is that in Embodiment 1, the spam contact information in the spam contact database is configured by the administrator, while in this embodiment Among them, the chat system analyzes the information, and configures the contact information that meets the spam contact information requirements into the spam contact information database.

[0069] In order to realize the information filtering method in the second embodiment, it is necessary to set the spam contact information database as in the first embodiment, and also need to set the occurrence threshold. The occurrence threshold is used to record the contact information as spam contact information in the spam contact information database when the number of occurrences of a certain contact information exceeds the occurrence threshold. Wherein, the unit of the occurrence threshol...

Embodiment 3

[0084] In the invention, in addition to filtering the information to be sent by only relying on the spam contact method, it is also possible to further filter the information to be sent by using a commonly used information filtering method after filtering the information to be sent by using the spam contact method. In the present invention, commonly used information filtering methods are collectively referred to as information filtering methods, and the filtering method based on spam contact information used in the present invention is referred to as spam contact information filtering method. Specifically:

[0085] In the method described in Embodiment 1 and Embodiment 2, before sending the information to be sent, the information filtered by the junk contact method is further pre-filtered with an information filtering method to determine whether it is advertisement information, and if so, then filter the information; Otherwise, send the message that currently passes the messag...

Abstract

The method sets up a junk contact mode data base and comprises: A) deciding if the message to be sent carries the contact mode; if yes, then entering the step B; otherwise, entering step D; B) extracting the contact mode carried in the message to be sent; deciding if there is a same contact mode in the junk contact mode database; if yes, entering the step C; otherwise, entering step D; C) rejecting the sending of the message to be sent, and ending the current process flow; D) sending the message to be sent. The invention also reveals an information filtering apparatus.

Description

technical field [0001] The invention relates to Internet technology, in particular to an information filtering method and device. Background technique [0002] In the current chat room advertisement filtering method, the method of keyword filtering is usually adopted to filter the chat information sent to the chat room. The method of keyword filtering collects keywords frequently appearing in advertisement information, judges each piece of chat information sent to the chat room, and judges whether the collected keywords exist in the chat information, and if so, filters out the keyword.
