1. Reasoning with Rough Sets and Paraconsistent Rough Sets
Sammanfattning : This thesis presents an approach to knowledge representation combining rough sets and para-consistent logic programming.The rough sets framework proposes a method to handle a specific type of uncertainty originating from the fact that an agent may perceive different objects of the universe as being similar, although they may have di®erent properties.

2. Indiscernibility and Vagueness in Spatial Information Systems
Sammanfattning : We investigate the use of the concept of indiscernibilityand vagueness in spatial information systems. To representindiscernibility and vagueness we use rough sets, respectivelyfuzzy sets. We introduce a theoretical model to supportapproximate queries in information systems and we show howthose queries can be used to perform uncertain classi. LÄS MER
