This paper proposes a method to represent human preference using impressions of items derived from users. Since such impressions are not known explicitly, we infer the impressions from information of tagging in a folksonomy. An inferred impression is called a “concept." In this study, we investigate validity of the concepts obtained by our previous method, and propose the new improved derivation method of concepts based on the results of the ivestigation. Experiments were carried out in order to evaluate the performance of the improved method through comparison with the previous method, and a recommendation experiment was carried out in order to confirm the usefulness of the representation of human preference using the concepts obtained by the new method.
