A collection of 21 papers summarizing recent developments in
fundamental research and practical tools for discovering dependencies
among data, and reasoning about vague, uncertain, and imprecise
information. They discuss such aspects as the generation of multiple
knowledge from databases based on rough set theory, data mining using
attribute-oriented generalization and information reduction,
maintaining reducts in the variable precision rough set model,
topological rough algebras, theories combining many equivalence and
subset relations, and resolving queries through cooperation in multi-
agent systems. Some of the papers have been expanded and updated from
a 1995 computer science conference.
