Complete and Incomplete Knowledge in Logical Information Systems

2001
We present a generalization of logic All I Know by presenting it as an extension of standard modal logics. We study how this logic can be used to represent complete and incomplete knowledge in Logical Information Systems. In these information systems, a knowledge base is a collection of objects (e.g., files, bibliographical items) described in the same

Integrated Study in Incomplete Information System

2009 International Conference on Artificial Intelligence and Computational Intelligence, 2009
Both rough set theory and D-S evidence theory are important methods in uncertainty reasoning, and each one has its own advantages and disadvantages. Incomplete information system exists widely in real life. In this paper, two theories are used in combination to study the incomplete information system.

A Control Problem for Parabolic Systems with Incomplete Information

2019
In this paper, abstract parabolic control systems in Hilbert space are considered. The state of the system is unknown, but there is an equation of measurement in discrete times. The initial state and disturbances are restricted by joint integral constraints.
