The invention discloses a user behavior-based log filtering method. The method comprises the following steps of 1, dividing a user behavior into multiple sub-behaviors, allocating corresponding weights, obtaining and storing log information of the user behavior through a distributed log collection tool, and extracting and filtering the log information of the corresponding sub-behaviors with the weights lower than a weight threshold; and 2, performing parallel processing on the reserved log information of the sub-behaviors through a utility function, establishing a mapping relationship between user interest degrees and sub-behavior indicators by the utility function, extracting and filtering the corresponding log information of the sub-behaviors with interest degrees lower than an interest degree threshold, reserving the log information of the sub-behaviors preferred by a user, forming an optimized data source of a recommendation result, and storing the optimized data source in a data cluster.
