Preprocessing method and system for operator gateway data

The invention belongs to the technical field of data processing, and provides a preprocessing method and system for operator gateway data. The preprocessing method comprises the steps that log data ofan operator gateway is acquired; the log data is filtered according to a preset filtering rule; a target data set containing a user search keyword field is extracted from log data obtained after filtering according to a regular expression; structuring processing is conducted on the target data set to obtain a structured target data set; the keyword field in the structured target data set is matched with a preset target character string, and a target user corresponding to the target character string is determined according to a matching result and user information corresponding to the target data set, wherein the user information is information for determining the user identity in the target data set. Compared with a traditional data preprocessing method, the processing effect of the datapreprocessing method on th
