AI Technical Summary

Technical Problem

In existing technologies, automatic comparison and extraction of stack information is inefficient and prone to misjudgment, while manual screening is time-consuming and difficult to extract effective stack information efficiently and accurately.

Method used

The first regular expression is used to match the original stack file to determine the target stack file, and the second regular expression is used to match the key information set. Valid stack information is determined by comparison, and invalid information is filtered out by combining the stack blacklist.

Benefits of technology

It improves the efficiency and accuracy of stack information extraction, reduces the time consumption and misjudgment of manual operations, and meets the personalized needs of real-world scenarios.

Abstract

Embodiments of the present disclosure relate to a stack information extraction method, device, equipment and medium, wherein the method comprises: obtaining an original stack file; matching the original stack file using a first regular expression to determine a target stack file, wherein the target stack file comprises stack files of two adjacent time units; matching the target stack file using a second regular expression to determine two sets of key information corresponding to the stack files of the two adjacent time units; and comparing the two sets of key information to determine effective stack information. By comparing the key information obtained by twice regular matching of the stack file, the effective stack information can be extracted, thereby improving the efficiency of stack information extraction and the accuracy of effective stack information extraction while avoiding time-consuming and easy-to-misjudge manual work.
