The scientific objectives of the "COnceptual gRAphs at LIrmm" project and the method used to reach these objectives are presented.

The objective of this study is to empirically examine the antecedents and dimensions of trust in inter-firm collaborative relationships. A conceptual model is introduced and tested on survey data. The resulting model is mainly supported, although some findings were unexpected.

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 that default CG rules provide a unifying framework for CG rules as well as polarized CGs (CGs with atomic negation). This framework allows us to study decidable subclasses of a new language mixing CG rules with atomic negation. In th...
