PROBLEM TO BE SOLVED: To reflect precisely meta-information imparted beforehand to each content to a mapping result, when mapping the content in a low-dimensional space. SOLUTION: When mapping the content to which the meta-information such as a classification system is imparted beforehand in a low-dimensional space such as a two-dimensional plane, concept vectors are allocated to each content in a high-dimensional mapping process, and then position information in the low-dimensional space is allocated to each content based on the concept vectors in a low-dimensional mapping process. In this case, the distance between the concept vectors is corrected so that, the nearer classified category information imparted beforehand to each content is, the nearer the position information in the low-dimensional space becomes, to thereby enable to be clustered so that a plurality of contents reflect the meta-information.
