Abstract

The invention discloses a method for automatically extracting features from a log stream. The method includes the following steps: acquiring features of a specified user from a log stream; aggregatingthe acquired features of the specified user by using an aggregation function so as to generate a feature vector corresponding to the user; according to the aggregated feature vector, constructing a basic feature vector; according to the basic feature vector, constructing a time sequence feature; generating training data according to the basic feature vector and the time sequence feature. The method and system aim to solve the problems that the log streams have many dimensions, and it is difficult to acquire time sequence information and to support refined operation of the user granularity, when automatically extracting a large number of user features from the log data stream.

Description

technical field [0001] The invention relates to the field of data stream analysis, in particular to a method and system for automatically extracting features from log streams. Background technique [0002] Log stream, that is, the data stream used to record product operation status or user behavior on the product side. Generally, the product client is used to record various click button information of the user during use, and the reported data of the client is received through the network or the server. Different from traditional static status signals, this type of data is a continuous dynamic sequence of characters, and the signals are sequenced and time-related. The log data stream records various behavior states of users on the product side, and is important operational information that characterizes users. Effective construction of user characteristics and status is one of the key technical difficulties in business refinement operation. In a nutshell, machine learning...
