Patent ID: 7860867

Claim:
An information managing system comprising: a parameter setting unit including a first processor configured to set a parameter representative of one or more user attributes of a user and one or more information attributes of items of information to be retrieved; an information relevance space generator including said first processor or a second processor configured to generate an information relevance space by placing the items of information to be retrieved onto a mapping space having one or more axes, based on the parameter set by said parameter setting unit, wherein: at least one of said one or more information attributes is an attribute other than content of said items of information to be retrieved, said information relevance space represents information indicative of the relevance and semantic closeness of said items of information and information indicative of the relevance and semantic closeness of users who retrieves and uses said items of information, and at least a first item and a second item of said items that are not relevant based on contents of said first and second items are determined highly relevant in said information relevance space; an output controller including at least one of said first and second processor or another processor configured to generate output information for outputting the information to be retrieved based on the information relevance space generated by said information relevance space generator, wherein said information relevance space generator comprises a weighting unit configured to generate said information relevance space by weighting nodes which are represented respectively by said user and said information to be retrieved; and an information relevance space manipulator including at least one of said first and second processor or another processor configured to instruct said information relevance space generator to change the generated information relevance space, wherein said information relevance space generator changes weights applied to said nodes to regenerate an information relevance space according to an instruction from said information relevance space manipulator.
