Title: RECOMMENDER SYSTEM FOR HETEROGENEOUS LOG PATTERN EDITING OPERATION
Abstract:
A heterogeneous log pattern editing recommendation system and computer- implemented method are provided. The system (600) has a processor (605) configured to identify, from heterogeneous logs, patterns including variable fields and constant fields. The processor (605) is also configured to extract a category feature, a cardinality feature, and a before-after n-gram feature by tokenizing the variable fields in the identified patterns. The processor (605) is additionally configured to generate target similarity scores between target fields to be potentially edited and other fields from among the variable fields in the heterogeneous logs using pattern editing operations based on the extracted category feature, the extracted cardinality feature, and the extracted before-after n-gram feature. The processor (605) is further configured to recommend, to a user, log pattern edits for at least one of the target fields based on the target similarity scores between the target fields in the heterogeneous logs.
