A method for generating a retrieval object map to be used for a method of retrieving retrieval object of sensuous image meeting with sensuous image of retrieving word among a plurality of retrieval objects on the basis of a given retrieving word using said retrieval object map, in which a plurality of expression word expressing sensuous images of retrieval objects on a virtual space depending upon degree of association of those sensuous images are arranged, comprising:
- storing an expression word map, in which a plurality of expression word expressing sensuous images of retrieval objects on a virtual space depending upon degree of association of those sensuous images are arranged, and storing said plurality of retrieval objects with correspondence to said expression words;
- and
- including a first position deriving step of deriving the expression word corresponded to said retrieval object or position of the expression word contained in each of said retrieving object in said virtual space, and a retrieving object map generation step of generating a retrieval object map arranging said respective retrieval objects on said virtual space on the basis of position derived at said first position deriving step.
