Title:
TRAFFIC FEATURE INFORMATION EXTRACTION METHOD, TRAFFIC FEATURE INFORMATION EXTRACTION DEVICE, AND TRAFFIC FEATURE INFORMATION EXTRACTION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2015/141560
Kind Code:
A1
Abstract:
Provided is a traffic feature information extraction method that is characterized by comprising a regular expression conversion step (32a), a clustering step (32b), and a feature information extraction step (32c). In the regular expression conversion step (32a), a preset item is extracted from a traffic log and a partial character string that is included in the item is converted into a regular expression on the basis of a predetermined rule. In the clustering step (32b), traffic log entries that have been converted into regular expressions are clustered. In the feature information extraction step (32c), entries that minimize the total distance between the clustered entries that are included in the traffic log are extracted as traffic feature information for each cluster.
