Information processing apparatus and information processing method, recording medium, and program
An information processing apparatus and an information processing method, a recording medium, and a program make it possible to generate a positive history vector and a negative history vector. A negative history vector is generated from initially registered contents. If the initially registered contents are not changed, and an operation log is supplied, whether or not the supplied operation log is a positive history is determined. When the supplied operation log is a positive history, a program vector corresponding to the operation log is additionally stored as a positive history, and a positive history vector is generated from a sum of program vectors. When the supplied operation log is a negative history, a program vector corresponding to the operation log is additionally stored as a negative history, and a negative history vector is generated from a sum of program vectors.
