Abstract
A data processing device (10) includes: a detection unit (11) that detects change points of a first data series including a first identifier and change points of a second data series including a second identifier; a calculation unit (12) that calculates an occurrence probability that the change points of the first data series and the change points of the second data series occur in synchronization with each other; an association unit (13) that associates the first identifier and the second identifier as identifiers related to a tracing target on the basis of the occurrence probability; and a determination unit (14) that determines a type of an identification target of the associated first or second identifier on the basis of the occurrence probability.
Claims18
A data processing device comprising:
- at least one memory storing instructions, and
- at least one processor configured to execute the instructions stored in the at least one memory to;
- detect change points of a first data series including a first identifier and change points of a second data series including a second identifier;
- calculate an occurrence probability that the change points of the first data series and the change points of the second data series occur in synchronization with each other;
- associate the first identifier and the second identifier as identifiers related to a tracing target when the occurrence probability is greater than a first threshold;
- and
- determine a type of an identification target of the associated first or second identifier on the basis of the occurrence probability.
A data processing method comprising:
- detecting change points of a first data series including a first identifier and change points of a second data series including a second identifier;
- calculating an occurrence probability that the change points of the first data series and the change points of the second data series occur in synchronization with each other;
- associating the first identifier and the second identifier as identifiers related to a tracing target when the occurrence probability is greater than a first threshold;
- and
- determining a type of an identification target of the associated first or second identifier on the basis of the occurrence probability.
