Abstract: In the information registered by a system, a learning model is associated with a dataset which is one or more dataset elements serving as an input of the learning model, and a dataset is associated with a filter of the dataset. The system evaluates the learning model using a processed dataset which is a dataset obtained on the basis of a dataset associated with an evaluation target learning model and a filter associated with the dataset. The system displays at least a part of information associated with a browsing target learning model and information indicating a result of evaluation of the learning model.

Abstract: An anomaly detection apparatus for detecting data flow anomalies classes a plurality of data flows on the basis of similarity in time series changes in the data amounts of the data flows; calculates a correlation coefficient at a normal time and a correlation coefficient at a certain timing between at least two data flows belonging to the same class; and determines that at least one of the at least two data flows is anomalous when a difference between the correlation coefficient at the normal time and the correlation coefficient at the certain timing is greater than a predetermined threshold.

Abstract: A log message grouping apparatus calculates a coincidence degree evaluation value E1 representing the degree of coincidence between minority words, which are relatively low occurrence frequency words, out of the words that form a log message and minority words in another log message. The log message grouping apparatus further calculates an occurrence degree evaluation value E2 representing the degree of occurrence of the combination of a classification value of a log message and the classification value of a past log message on the basis of the occurrence frequency of the combination of the classification values and calculates an association degree evaluation value E3 representing the degree of association between the log message and the past log message on the basis of the coincidence degree evaluation value E1 and the occurrence degree evaluation value E2.

Abstract: A management system constructs management information indicating that log chunks and issue chunks extracted from a first system managing log information and issue information output by a process related to a first team for a program to be developed are linked. The management system searches, from the management information, a log message group compatible with a designated log message group that is one or more log messages related to the issue by log pattern matching using the designated log message group in a case of receiving an inquiry with which the designated log message group is associated from the second system. The management system displays, on the second system, a response containing a handling method represented by handling method information corresponding to the found log message group.
