Information Processing System, Information Processing Method, Information Processing Device and Communication Terminal, and Method and Program for Controlling Same

A control method of an information processing device for assisting generation of social communication, based on user communication information exchanged through a network, the control method comprising:

• collecting the communication information;
• extracting life log information included in the collected communication information;
• storing the extracted life log information in a life log information storage unit in a configuration capable of being searched at least on an individual user unit basis, and memorizing scores of a plurality of indexes in the life log information storage unit while associating the scores with the life log information, the indexes indicating degrees of contribution of the life log information to new social communication generation;
• and
• managing the life log information stored in the life log information storage unit, based on a combination of the scores of the indexes.

A non-transitory computer-readable recording medium storing a control program of an information processing device for assisting generation of social communication, based on user communication information exchanged through a network, the control program causing a computer to execute:

• collecting the communication information;
• extracting life log information included in the collected communication information;
• storing the extracted life log information in a life log information storage unit in a configuration capable of being searched at least on an individual user unit basis, and memorizing scores of a plurality of indexes in the life log information storage unit while associating the scores with the life log information, the indexes indicating degrees of contribution of the life log information to new social communication generation;
• and
• managing the life log information stored in the life log information storage unit, based on a combination of the scores of the indexes.

An information processing system for assisting generation of social communication, based on user communication information exchanged through a network, the information processing system comprising:

• a communication information collection unit that collects the communication information;
• a life log information extraction unit that extracts life log information included in the collected communication information;
• a life log information storage unit that stores the extracted life log information in a configuration capable of being searched at least on an individual user unit basis, the life log information storage unit memorizing scores of a plurality of indexes while associating the scores with the life log information, the indexes indicating degrees of contribution of the life log information to new social communication generation;
• a life log information management unit that manages the life log information stored in the life log information storage unit, based on a combination of the scores of the indexes;
• and
• an information provision unit that selects guidance information or advertising information to be provided to a predetermined user, using the stored life log information and the scores of the indexes, and provides the selected guidance information or advertising information through a communication terminal being used by the predetermined user.
