The present invention relates to an information processing apparatus and an information processing method, a recording medium, and a program that make it possible to generate a positive history vector and a negative history vector. In step S 71 , a negative history vector is generated from initially registered contents. When it is determined in step S 72 that the initially registered contents are not changed, and when it is determined in step S 73 that an operation log is supplied, whether or not the supplied operation log is a positive history is determined in step S 74 . When the supplied operation log is a positive history, a program vector corresponding to the operation log is additionally stored as a positive history in step S 75 , and a positive history vector is generated from a sum of program vectors in step S 76 . When the supplied operation log is a negative history, a program vector corresponding to the operation log is additionally stored as a negative history in step S 77 , and a negative history vector is generated from a sum of program vectors in step S 78 . The present invention is applicable to a program recommendation processing device.
