Abstract:

Cognitive Maps (CMs) have shown promise as tools for modelling and simulation of knowledge in computers as representation of real objects, concepts, perceptions or events and their relations. This thesis examines the application of fuzzy theory to the expression of these relations, and investigates the development of a framework to better manage the operations of these relations. The Fuzzy Cognitive Map (FCM) was introduced in 1986 but little progress has been made since. This is because of the difficulty of modifying or extending its reasoning mechanism from causality to relations other than

Abstract:

The decision problem in set theory has been intensively investigated in the last decades, and decision procedures or proofs of undecidability have been provided for several quantified and unquantified fragments of set theory. In this thesis we study the decision problem for three novel quantified fragments of set theory, which allow the explicit manipulation of ordered pairs. We present a decision procedure for each language of this family, and prove that all of these procedures are optimal (in the sense that they run in nondeterministic polynomial-time) when restricted to formulae with

Abstract:

Information Systems and software embed knowledge about the domain in which they operate. This knowledge can be very useful to various stakeholders in the organization, including developers, users, and other organizational workers. However, it is not readily accessible and usually intertwined with implementation details. Making this knowledge available would be beneficial for several reasons. In particular: 1) software often needs to be updated to reflect changes in the organization; this causes the embedded knowledge to stay current; 2) the actual system development process often incorporates

These metrics address three broad categories of question: Is the representation sufficiently expressive to perform its task? What implications has its design on the architecture of the system using it? What inefficiencies are intrinsic to its design? An evaluation of existing Know

Systems need knowledge to behave intelligently in a complex environment. This thesis presents a formalism for characterizing the knowledge in a world while providing a framework that can be utilzed efficiently in computation. Thus Domain Theory is developed as a knowledge representation scheme. Under Domain Theory, the knowledge in a world is divided into domains that are interrelated through the relation of representation. This theory is evaluated as appropriate for knowledge representation using descriptive and procedural adequacy criteria. Domain Theory is applied to produce a working sys

Abstract:

Designing systems with the ability to make optimal decisions under uncertainty is one of the goals of artificial intelligence. However, in many applications the design of optimal planners is complicated due to imprecise inputs and uncertain outputs resulting from stochastic dynamics. Partially Observable Markov Decision Processes (POMDPs) provide a rich mathematical framework to model these kinds of problems. However, the high computational demand of solution methods for POMDPs is a drawback for applying them in practice.<br>In this thesis, we present a two-fold approach for improving the trac

Moreover, a multi-model sensory module is proposed to perceive the objects in the environment and build the ontological knowledge.
