Content processing device, content processing method, computer-readable recording medium, and integrated circuit

A content processing method for implementing a content processing device which processes at least one or more contents, the method comprising:

• an input step of receiving input of the content, and designation of shared users, the shared users being at least one or more users who share the content;
• a shared user information managing step of managing shared user information relating to the shared users;
• a content information managing step of managing meta-information corresponding to the content;
• a social information managing step of calculating, at every predetermined time period, social information that defines a relationship between the users and a degree of intimacy indicating a degree of closeness between the users in terms of a numerical value;
• a social information history accumulation step of accumulating the social information at the every predetermined time period for calculating the social information;
• and
• a priority determination step of determining an evaluation time period out of the predetermined time periods based on the meta-information, calculating a degree of intimacy between the shared users received in the input step during the evaluation time period based on the social information, and determining a priority of the evaluation time period according to the calculated degree of intimacy, the evaluation time period being a time period when a content was generated, wherein
• in the priority determination step, a priority of the content generated during the evaluation time period is determined based on a degree of intimacy between subjects included in the content generated during the evaluation time period.

A computer-readable recording medium which stores a program which causes a computer to function as a content processing device for processing at least one or more contents, the program causing the computer to function as:

• a shared user information managing unit which manages shared user information relating to shared users, the shared users being at least one or more users who share the content received by an input unit;
• a content information managing unit which manages meta-information corresponding to the content;
• a social information managing unit which calculates, at every predetermined time period, social information that defines a relationship between the users and a degree of intimacy indicating a degree of closeness between the users in terms of a numerical value;
• a social information history accumulation unit which accumulates the social information at the every predetermined time period for calculating the social information;
• and
• a priority determination unit which determines an evaluation time period out of the predetermined time periods based on the meta-information, calculates a degree of intimacy between the shared users received by the input unit during the evaluation time period based on the social information, and determines a priority of the evaluation time period according to the calculated degree of intimacy, the evaluation time period being a time period when a content was generated, wherein
• the priority determination unit determines a priority of the content generated during the evaluation time period, based on a degree of intimacy between subjects included in the content generated during the evaluation time period.

An integrated circuit in a content processing device for processing at least one or more contents, comprising:

• a shared user information managing unit which manages shared user information relating to shared users, the shared users being at least one or more users who share the content received by an input unit;
• a content information managing unit which manages meta-information corresponding to the content;
• a social information managing unit which calculates, at every predetermined time period, social information that defines a relationship between the users and a degree of intimacy indicating a degree of closeness between the users in terms of a numerical value;
• a social information history accumulation unit which accumulates the social information at the every predetermined time period for calculating the social information;
• and
• a priority determination unit which determines an evaluation time period out of the predetermined time periods based on the meta-information, calculates a degree of intimacy between the shared users received by the input unit during the evaluation time period based on the social information, and determines a priority of the evaluation time period according to the calculated degree of intimacy, the evaluation time period being a time period when a content was generated, wherein
• the priority determination unit determines a priority of the content generated during the evaluation time period, based on a degree of intimacy between subjects included in the content generated during the evaluation time period.
