Imprecision and Uncertainty in the UFO Database Model.
Peer reviewed Peer reviewed
Van Gyseghem, Nancy; De Caluwe, Rita – Journal of the American Society for Information Science, 1998
Discusses how imprecision and uncertainty are dealt with in the UFO (Uncertainty and Fuzziness in an Object-oriented) database model. Such information is expressed by means of possibility distributions, and modeled by means of the proposed concept of "role objects." The role objects model uncertain, tentative information about objects,…
