Computer-readable recording medium, extraction device, and extraction method

摘要

When a second pattern is to be generated by adding an event to a first pattern including events, an extraction program causes a computer to execute the following process based on combinations of events. That is, the extraction program causes the computer to generate the second pattern when the number of occurrence, in the second pattern, of each of the events included in the combinations is not more than a threshold. The extraction program causes the computer to calculate, based on data including a plurality of events, a frequency at which one or more of the generated second patterns occur in the data. The extraction program causes the computer to extract the second pattern having the frequency satisfying a predetermined condition. The extraction program causes the computer to add a new event to the extracted second pattern.

1. A non-transitory computer-readable recording medium having stored therein an extraction program that causes a computer to execute a process comprising:
when a second pattern is to be generated by adding an event to a first pattern including events, generating the second pattern when, based on combinations of events stored in a storage unit, number of occurrence, in the second pattern, of each of the events included in the combinations is not more than a threshold; based on data including a plurality of events stored in the storage unit, calculating a frequency at which the second pattern occurs in the data; extracting the second pattern having the frequency satisfying a predetermined condition; and adding an event to the extracted second pattern.
