The embodiment of the invention discloses a method and device for identifying abnormal transactions. The method comprises the following steps of identifying whether the target transaction is an abnormal transaction through a strong rule model after receiving target transaction data of a certain target transaction, judging whether the target transaction is an abnormal transaction through a transaction context model when the target transaction is recognized as an abnormal transaction. According to the method, the transaction is further recognized through a transaction context model after an abnormal transaction is identified through the strong rule model. The relevance between the target transaction and the historical transaction is considered, and the accuracy of identifying the abnormal transaction is improved. On the other hand, the strong rule model in the embodiment is generated by combining with artificial experience, so that the machine experience and the manual experience are fully considered in the judgment process of whether the transaction is abnormal. The accuracy of identifying abnormal transactions is improved.
