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.

Abstract translation: 提供了异构日志模式编辑推荐系统和计算机实现的方法。 系统（600）具有配置成从异构日志中识别包括可变字段和常量字段的模式的处理器（605）。 处理器（605）还被配置为通过对所识别的模式中的变量字段进行标记来提取类别特征，基数特征以及之前后的n元特征。 处理器（605）另外被配置为使用基于提取的类别特征，提取的基数特征和基于所提取的类别特征的模式编辑操作，从而在可能编辑的目标字段与异构日志中的可变字段之中的其他字段之间生成目标相似度分数 在n-gram特征前后提取。 处理器（605）还被配置为基于异构日志中的目标字段之间的目标相似度分数向用户推荐至少一个目标字段的日志模式编辑。
