Abstract. In this paper, we extend Simple Conceptual Graphs with Reiter’s default rules. The motivation for this extension came from the type of reasonings involved in an agronom...
We investigate the complexity and expressive power of a spatial logic for reasoning about graphs. This logic was previously introduced by Cardelli, Gardner and Ghelli, and provide...
Abstract. In this paper, we explore the expressivity of default CG rules (a CGoriented subset of Reiter’s default logics) through two applications. In the first one, we show tha...
Our goal is to model the way people induce knowledge from rare and sparse data. This paper describes a theoretical framework for inducing knowledge from these incomplete data descr...
This paper describes a theoretical framework for inducing knowledge from incomplete data sets. The general framework can be used with any formalism based on a lattice structure. It...
