Provided are a method, an apparatus and a computer program for calculating a risk assessment value for an event sequence, which are capable of calculating the risk assessment value of each even sequence by calculating a totally ordered set on the basis of a partially ordered set indicating the event sequence. The risk assessment value of an event sequence that is a partially ordered set indicating some events of an event group of M kinds of events (M is a finite natural number) in a time series. The partially ordered set is converted into an approximate totally ordered set, and an M-dimensional feature vector is calculated based on the totally ordered set obtained by the conversion. A projection matrix for calculating the risk assessment value is calculated using the calculated M-dimensional feature vector.
An apparatus configured to calculate a risk assessment value of an event sequence which is a partially ordered set indicating some events of an event group of M kinds of events in a time series, wherein M is a finite natural number, the apparatus comprising:
A computer readable storage medium having computer readable instructions stored thereon that, when executed by a computer, implement a method of determining a risk assessment value of an event sequence which is a partially ordered set indicating some events of an event group of M kinds of events in a time series, wherein M is a finite natural number, the method comprising:
