Embodiment approach

[0094] In a first possible implementation manner, extract at least one keyword from the target message; detect whether the extracted keyword exists in the keyword whitelist; if the extracted keyword does not exist in the keyword whitelist, determine The target message is not a message that allows repeated sending.

[0095] Wherein, the keyword whitelist includes at least one keyword. The keywords in the keyword whitelist refer to words or emoticons that users are allowed to send repeatedly, usually some common words or emoticons that appear frequently.

[0096] The violation processing server may use a keyword extraction algorithm to extract at least one keyword from the target message. For example, the violation processing server may split the string corresponding to the message content into one or more substrings, each substring corresponding to a keyword. Afterwards, the violation processing server detects whether the extracted keyword exists in the keyword whitelist; if ...

Abstract

The invention discloses an information filtering method and device, and belongs to the technical field of computers and the Internet. The method includes the steps of obtaining target information sent by a target user; calculating the total amount of similar information sent by the target user within a preset time duration, wherein the similar information refers to information which has the whole information content the same as the target information or a part of keywords the same as the target information; detecting whether the total amount reaches a preset threshold value or not; filtering out the target information if yes. By means of the method and device, the problem that in the prior art, judgment omission still happens to some junk information is solved; junk information which is the same or similar and is repeatedly sent is filtered out, the judgment accuracy of junk information is improved, and the judgment omission rate is decreased.

Description

technical field [0001] The invention relates to the technical fields of computers and the Internet, in particular to a message filtering method and device. Background technique [0002] With the rise of social applications, various applications with multi-person chat interaction functions have emerged. For example, a group chat application that supports multi-person chat and interaction in units of groups, a live broadcast application that supports multi-person chat and interaction in units of channels (or rooms), and so on. [0003] However, some users often send some spam messages, such as advertisement messages, fraud messages or messages containing bad content, during the chatting process. These spam messages seriously affect the normal chat interaction between users. In the related technology, the content of the message sent by the user is analyzed and identified to determine whether the message contains illegal words, and if the message contains illegal words, the me...
