Abstract: A recording medium stores a program for causing a computer to execute a process including: referring to a memory storing data constituted by combinations of features to extract data groups of which the combinations satisfy each condition; identifying relationships between the features included in the data groups; classifying the relationships into a first clusters, based on first similarity; classifying the data groups into second clusters, based on second similarity; classifying the data groups into third clusters so as to classify, into a same cluster, data groups that are in a same one first cluster obtained by classifying the relationships corresponding correspond to each data group and are in a same one second cluster obtained by classifying each data group; identifying first conditions for classifying the data groups classified into each cluster and the data groups classified into other clusters; and outputting the identified first conditions with a classification result.

Abstract: A non-transitory computer-readable recording medium stores therein a detection program that causes a computer to execute a process including: extracting a predetermined event from events included in a past log and extracting a plurality of associated events associated with the predetermined event, for each of the predetermined event, over a predetermined time width designating the predetermined event as a starting point; creating pattern data corresponding to the predetermined event and the associated events; constructing a learning model in which the pieces of pattern data are connected in chronological order of the predetermined event; and detecting abnormality based on a collation result between the learning model and event data input according to an occurring event.

Abstract: A non-transitory computer-readable recording medium stores a program that causes a computer to execute a process including: performing a first conversion processing to convert a value indicating each event, and to convert, based on conversion information that indicates a group of the value and an identification value that corresponds to values belonging to the group; constructing information with occurrence probabilities by connecting identification values; performing second conversion processing to convert a value indicating each event included in event data, and to convert values that belong to a group indicated in the conversion information into an identical identification value corresponding to the group based on the conversion information; and detecting an anomaly based on a result of comparison between the constructed information and the identification value.
