Easy and correct estimation of a relationship between entities is made possible. An entity relationship estimation apparatus that estimates a relationship between a plurality of entities each executing a process is configured to include: a window-based correlation and traffic volume estimation unit that acquires traffic data of a plurality of entities, and calculates correlation values in one or more windows of a predetermined time width of each traffic data of at least one entity pair; and a relationship type estimation unit that estimates a type of relationship between entities of the entity pair based on the correlation values of the windows of the entity pair.

Entity relationship estimation apparatus, entity relationship estimation method, and recording medium

A log labeling apparatus is configured to include a label importance DB and a similarity DB configured to store importance information between a plurality of labels and an action set and action set information identifying a first action set for calculating a second similarity with each label of a first log unit, a similarity calculation unit configured to calculate the second similarity with each label of the first log unit on the basis of the importance information, an action set of the first log unit, and the action set of the action set information, a post processor configured to detect label candidates, and an accumulation determination unit configured to determine a second action set for calculating a second similarity of a second log unit and to store action set information on the second action set in the similarity DB.
