An information processing device and an information processing method, a recording medium, and a program for generating a positive history vector and a negative history vector. A negative history vector is generated from initially registered contents in step S71. If it is judged in step S72 that the initially registered contents are not changed and judged in step S73 that an operation log is supplied, a check is made in step S74 to see if the supplied operation log is a positive history. If the supplied operation log is a positive history, the broadcast program vector corresponding to the operation log is additionally stored as a positive history in step S75, and a positive history vector is generated from the total of broadcast program vectors in step S76. If the supplied operation log is a negative history, the program vector corresponding to the operation log is additionally stored as a negative history in step S77 and a negative history vector is generated from the total of the broadcast program vectors in step S78. The present invention is applicable to a broadcast program recommendation processing device. |
