In this paper we examine issues involving measures of creativity for attribute data generalization using hierarchies. In particular we consider consensus and specificity measures for the partitions that result using crisp concept hierarchies. We note that fuzzy hierarchies do not produce partitions of data in general so some approaches to considering degrees of partitioning is described.
This paper proposes a possibilistic database model that enables dealing with incomplete possibility distributions. The situation considered is that where the data provider does not have a complete knowledge of the attribute domains involved and is only able to specify more or less possible and completely impossible candidates for some attribute values. It is shown that the framework we propose constitutes...
Semantic category theory indicates that human thinking involves four, entirely distinct types of information processing, each associated with a totally independent dasiasemantic categorypsila. However, observation also indicates that human cognition does not enforce strong data typing. Whilst this enables the creation of beautiful poetry and prose, weak data typing can also lie at the heart of persuasive...
