          <dc:description>知的な情報アクセスにおける人間的な主観の重要性を改めて指摘し，それに適したデータモデルを紹介する．本モデルは，従来のデータモデルの代数的な操作とは異なる幾何学的な操作を持ち，それは主観的な視点に応じた情報の関連性の強弱で張られる関数空間上で行なわれる．また，情報幾何学のα?分布族によるモデルの具現化を考え，ファジィ論理や確率的情報検索モデル，さらにはマーケティングサイエンスにおける個人選好モデルとの接点を示す．嗜好性を表す関数空間上で，これらは統一的に議論できるかも知れない．</dc:description>
          <dc:description>We will point out the importance of subjectivity on intellectual information accesses, because we may require human knowledge rather than machine data in the processes of comprehension and creation. On this point, we introduce a new data model suitable for such accesses. It has geometrical data operations on a function space which consists of the degree of relations for information flagments (e.g. Home Pages) from subjective viewpoints, comparing with the conventional data models with algebraic operations. It is shown that our data model defined by the α-family of distributions in information geometry has a relation with Fuzzy logic and a probablistic model of information retrieval. Further, we show another relation with mathematical models of personal preference in marketing science. We may totally consider these different types of models in the function space of preference.</dc:description>
