Meaning and Form in Event Calculus Edgar Andrade Abstract: This thesis is two fold. The first part deals with an existence proof of a formal algorithm that takes a narrative discourse and returns its semantic repre sentation in the Event Calculus (EC from now on). This algorithm uses Discourse Representation Theory, and takes on the form of a translation from Discourse Representation Structures to Scenarios and Integrity Constraints in EC. The second part, under a Cognitive-Functional approach, deals with the closely intertwined tasks of providing tools for the formalization of Construction Grammar, and to give the first few steps towards a more flexible algorithm for the semantic representation in the EC. Keywords: Event Calculus, Discourse Representation Theory, Construction Grammar, Formal Semantics, Cognitive-Functional Linguistics.
