Attribute information processing device, attribute information processing method and attribute information evaluation system

An attribute information processing method performed by a computer and including:

• acquiring attribute information including an attribute type and an attribute value indicating a state or value of the attribute type;
• acquiring at least two types of attribute values including a first-type attribute value and a second-type attribute value each corresponding to an attribute value of the acquired attribute information;
• determining a function for obtaining an evaluation value from the acquired at least two types of attribute values;
• determining an acquisition source of the first-type attribute value to be a first-attribute providing device that can provide the first-type attribute value concerning attribute information serving as a comparison target;
• determining an acquisition source of the second-type attribute value to be a second-attribute providing device different from the first-attribute providing device;
• generating attribute evaluation information containing information on the function, an evaluation value, information for identifying the first-attribute providing device, and information for identifying the second-attribute providing device;
• outputting the second-type attribute value so as to be stored in the second-attribute providing device serving as the acquisition source of the second-type attribute value;
• and
• outputting the attribute evaluation information to be used for evaluating the acquired attribute information and the attribute information serving as the comparison target.

An attribute information evaluation system including an attribute information processing device that processes attribute information including an attribute type and an attribute value indicating a state or value of the attribute type, a first-attribute providing device that holds attribute information serving as a comparison target, a second-attribute providing device, and an evaluation device,

• said attribute information processing device comprising:
• an attribute information acquiring unit that acquires the attribute information;
• an attribute value acquiring unit that acquires at least two types of attribute values including a first-type attribute value and a second-type attribute value each corresponding to an attribute value of the attribute information acquired by the attribute information acquiring unit;
• a generating unit that determines a function for obtaining an evaluation value from the at least two types of attribute values acquired by the attribute value acquiring unit, and generates attribute evaluation information containing information on the function, an evaluation value, information for identifying the first-attribute providing device serving as an acquisition source of the first-type attribute value, and information for identifying the second-attribute providing device serving as an acquisition source of the second-type attribute value;
• and
• an output unit that outputs the second-type attribute value acquired by the attribute value acquiring unit and the attribute evaluation information generated by the generating unit,
• said first-attribute providing device comprising
• a transmitting unit that, in response to a request from the evaluation device, transmits a first-type attribute value corresponding to an attribute value of the attribute information serving as the comparison target to the evaluation device,
• said second-attribute providing device comprising:
• a storage unit that stores, in a second-type attribute value storage unit, the second-type attribute value outputted by the output unit of the attribute information processing device;
• and
• a transmitting unit that, in response to a request from the evaluation device, transmits the second-type attribute value stored in the second-type attribute value storage unit to the evaluation device, and
• said evaluation device comprising
• an evaluation unit that:
• acquires the first-type attribute value and the second-type attribute value from the first-attribute providing device and the second-attribute providing device on the basis of information on the acquisition sources of the first-type attribute value and the second-type attribute value contained in the attribute evaluation information outputted by output unit of the attribute information processing device;
• and
• calculates a new evaluation value by applying the acquired first-type attribute value and second-type attribute value to the function contained in the attribute evaluation information;
• and
• evaluates the attribute information acquired by the attribute information acquiring unit of the attribute information processing device and the attribute information serving as the comparison target by comparing the new evaluation value with the evaluation value contained in the attribute evaluation information.
