Abstract
An information processing apparatus, an information processing method, a recording medium, and a program for generating preference information based on consecutively and inconsecutively viewed programs recommends the programs matching a user's preferences. A preference information extraction unit extracts program preference information based on metadata about programs and records a history of viewing of the programs. Preference information about a program that has been viewed for the first time is recorded as special program preference information. User preference information is generated on the basis of information about the preferred programs whose viewing count has exceeded a threshold value. A control unit automatically makes recording reservations of the programs whose viewing count has exceeded the threshold value. If an automatic recording reservation is canceled, a preference information updating unit updates the user preference information to reflect the metadata about the program whose recording reservation has been canceled.
