ECD Knowledge Representation : Fundamental Concepts of the Unit Graphs Framework (Représentation des connaissances du DEC: Concepts fondamentaux du formalisme des Graphes d'Unités) [in French]

ECD Knowledge Representation : Fundamental Concepts of the Unit Graphs Framework In this paper we are interested in the choice of a knowledge representation formalism that enables the representation, manipulation, query, and reasoning over linguistic knowledge of the Explanatory and Combinatorial Dictionary (ECD) of the Meaning-Text Theory. We show that neither the semantic web formalisms nor the Conceptual Graphs Formalism suit our needs, and justify the introduction of a new formalism denoted Unit Graphs. We introduce the core of this formalism which is the Unit Types hierarchy, and present Unit Graphs and how one may use them to represent aspects of the ECD.
