The invention discloses a method and device for processing a user behavior sequence, equipment and a storage medium. The method comprises the following steps: acquiring a first training sample set, wherein the first training sample set comprises a positive sample pair and a negative sample pair of a contrast learning task generated according to a behavior sequence data set; performing first training on the neural network model by using the first training sample set to obtain an initial similarity analysis model, wherein the first training comprises performing the first training on the neural network model according to the positive sample pair and the negative sample pair of the contrast learning task to obtain the initial similarity analysis model; performing second training on the initial similarity analysis model by using a second training sample set to obtain a similarity analysis model, wherein the second training sample set comprises training samples and training labels; the similarity analysis model is
