Abstract

Techniques for filtering information are described herein. In accordance with the present disclosure, a text acquisition module is configured to acquire text content to be filtered and a scanning module is configured to scan the text content to be filtered. The disclosed techniques scan the text content through a preset keyword dictionary, record a position of each keyword in the text content and acquire character pitch between keywords in the text content according to the position of each keyword in text content. A pitch judgment module is configured to judge whether the character pitch exceeds a preset character pitch and filter the keyword(s) in the text content in response to a determination that the character pitch exceeds the preset character pitch.
