Method and device for predicting intention index of account to execute transaction behavior

The invention discloses an intention index prediction method and device for an account to execute a transaction behavior. Relates to the field of data processing, and the method comprises the steps: receiving and responding to an intention index prediction request, determining time sequence transaction data, related to a target transaction behavior, of a target account in a past time period before the current time, and determining account attribute information corresponding to the target account; performing clustering processing on the time sequence transaction data to obtain a first clustering result that the time sequence transaction data belongs to a target transaction cluster in the P transaction clusters, and performing clustering processing on the account attribute information to obtain a second clustering result that the account attribute information belongs to a target attribute cluster in the Q attribute clusters; according to the first clustering result and the second clustering result, determining
