Abstract

The present disclosure relates to a method, a device, and a computer program product for abnormality detection. The method provided by embodiments of the present disclosure includes: acquiring information related to a target request initiated by a client terminal to an application and at least one context request, the information at least indicating the type and initiation time of the target request and the type and initiation time of the at least one context request; converting the acquired information into a vectorized feature representation for the target request; and determining an abnormality detection result of the target request based on the vectorized feature representation and using an abnormality detection model, the abnormality detection result indicating whether the target request is an abnormal request, and the abnormality detection model characterizing a correlation between a vectorized feature representation for a request and an abnormality detection result.
