Uncertainty as a Function of Expertise,tabase and the reliability of data depends on the reliability of the contributing sources. While IST is capable of managing inaccurate data, it is incapable of accommodating reliability revision of sources and apparently can not assign reliability to sources as a function of their expertise.

Unnesting Fuzzy SQL Queries in Fuzzy Databases,e N, type J, type JA, and nested queries with quantifiers. We show that by unnesting the queries, efficiency can be improved significantly. The results obtained in the paper form the basis for unnesting fuzzy queries of arbitrary blocks in fuzzy databases.

A Logical Explication of the Concepts of Incomplete and Uncertain Information,g certain aspects called attributes in this paper. We describe a fragment of a discovered reality as an . (cf. Pawlak [1,3,4]), which consists of the . of all the objects of this reality we are concerned with, and of a set A of . understood as functions each of which assigns to every object of . 1)

Evolution of Intelligent Database Systems: A Personal Perspective,been considerable research into extending databases into knowledge-bases. One approach to knowledge-bases that has evolved from database research is based on deductive databases. (See Ceri, et. al. [8] and Ullman [40, 41] for excellent introductions to the subject.
