Abnormal text recognition method and device, electronic equipment and storage medium

The invention provides an abnormal text recognition method and device, electronic equipment and a storage medium, and relates to the technical field of artificial intelligence, in particular to the technical field of information security and natural language processing. According to the implementation scheme, a first text feature of a to-be-recognized text is extracted; based on the first text feature, a target abnormal text is determined from a preset abnormal text library, and the similarity between a second text feature of the target abnormal text and the first text feature is larger than or equal to a similarity threshold value; obtaining a confidence coefficient of the target abnormal text, wherein the confidence coefficient is used for representing an abnormal degree of the target abnormal text; and determining whether the to-be-recognized text is an abnormal text or not based on the similarity and the confidence coefficient. 本公开提供了一种异常文本识别方法及装置、电子设备和存储介质，涉及人工智能技术领域，尤其涉及信息安全、自然语言处理技术领域。实现方案为：提取待识别文本的第一文
