Abstract
If content having an attribute different from that of content usually used by a user is selected, the present invention allows proper content recommendation in accordance with the selection. When notified from a control block of a selected piece of music, a short-term preference vector generation block gets music vector of that piece of music from a music vector storage block and stores obtained music vector into a short-term preference vector storage block as short-term preference vector. A recommendation block computes a difference between short-term preference vector and long-term preference vector and, by use of a weight based on the computed difference, determines a piece of music to be recommended to a user, thereby recommending the determined piece of music to the user.
Claims16
An information processing apparatus for managing long-term preference information of a user on the basis of an attribute information indicative of an attribute of content selected by a user, comprising:
- short-term preference information generation means for generating short-term preference information from attribute information of content selected in a predetermined period;
- and
- decision means for determining content to be recommended to a user by use of a difference between said long-term preference information and said short-term preference information.
An information processing method for managing long-term preference information of a user on the basis of an attribute information indicative of an attribute of content selected by a user, comprising the steps of:
- generating short-term preference information from attribute information of content selected in a predetermined period;
- and
- determining content to be recommended to a user by use of a difference between said long-term preference information and said short-term preference information.
A program to be executed by a processor for controlling an information processing apparatus for managing long-term preference information of a user on the basis of attribute information indicative of an attribute of content selected by a user, comprising the steps of:
- generating short-term preference information from attribute information of content selected in a predetermined period;
- and
- determining content to be recommended to a user by use of a difference between said long-term preference information and said short-term preference information.
An information processing apparatus for managing long-term preference information of a user and controlling a predetermined apparatus on the basis of information associated with content selected by a user, comprising:
- short-term preference information generation means for generating short-term preference information from attribute information indicative of an attribute of content selected during a predetermined period;
- and
- control means for controlling said apparatus on the basis of a difference between said long-term preference information and said short-term preference information.
An information processing method for an information processing apparatus for managing long-term preference information of a user and controlling a predetermined apparatus on the basis of information associated with content selected by a user, comprising the steps of:
- generating short-term preference information from attribute information indicative of an attribute of content selected during a predetermined period;
- and
- controlling said apparatus on the basis of a difference between said long-term preference information and said short-term preference information.
A program to be executed by a processor for controlling an information processing apparatus for managing long-term preference information of a user and controlling a predetermined apparatus on the basis of information associated with content selected by a user, comprising the steps of:
- generating short-term preference information from attribute information indicative of an attribute of content selected during a predetermined period;
- and
- controlling said apparatus on the basis of a difference between said long-term preference information and said short-term preference information.
An information processing apparatus for managing long-term preference information of a user on the basis of an attribute information indicative of an attribute of content selected by a user, comprising:
- a short-term preference information generation section for generating short-term preference information from attribute information of content selected in a predetermined period;
- and
- a decision section for determining content to be recommended to a user by use of a difference between said long-term preference information and said short-term preference information.
An information processing apparatus for managing long-term preference information of a user and controlling a predetermined apparatus on the basis of information associated with content selected by a user, comprising:
- a short-term preference information generation section for generating short-term preference information from attribute information indicative of an attribute of content selected during a predetermined period;
- and
- a control section for controlling said apparatus on the basis of a difference between said long-term preference information and said short-term preference information.
