| Uncertainty in Knowledge Representation and Reasoning |
| |
Description |
Rather than focusing on a single approach (like possibility theory), the tutorial aims at providing a coherent picture of several topics which have received considerable attention in the uncertainty field in recent years. After the discussion of a typology of imperfect information (uncertainty, variability, indiscernibility, fuzziness, contradiction), we will discuss the following topics and their relationships:
* uncertainty due to lack of knowledge: subjective probability and possibility theory
* qualitative representations of uncertainty: from classical logic to kappa functions
* possibilistic logic vs fuzzy logic: degree of truth vs. degree of uncertainty
* basics of random sets, upper/lower probability, evidence theory
* conditional probability and conditioning outside probability
* basic modes of information fusion

| Belief Revision: Modeling the Dynamics of Information Systems |
| |
Description |
An information system characterizes a view of the world with which it interacts, and broadly speaking, its input can take two forms; a query or an impetus for change. Physically the information held by an information system might be a diagram, a graph, a spreadsheet, a database, a rulebase, or a more sophisticated cognitive entity.
More often than not, information is uncertain and subject to change; this is the case even for simple database systems. Consequently an information system requires a mechanism for modifying its view as more information about the world is acquired.
This tutorial will focus on modeling the behaviour of an information system as it receives new information. In particular, a computational model for changing an information system will be presented together with the necessary background knowledge to implement it. Several real world applications of this model will be illustrated. |
