We propose an unfolding semantics for graph transformation systems in the double-pushout (DPO) approach. Mimicking Winskel’s construction for Petri nets, a graph grammar is unfolded into an acyclic branching structure, that is itself a (nondeterministic occurrence) graph grammar describing all the possible computations of the original grammar. The unfolding can be abstracted naturally to a prim...

This paper gives a brief overview of some of the primary arguments for Radical Construction Grammar (Croft 2001). Radical Construction Grammar is a theory of syntactic representation which is compatible with—in fact, I believe, is a consequence of—the facts of the grammars of human languages. In fact, Radical Construction Grammar proposes an extremely minimalist model of syntax from a universal...

Developing technologies that support collaboration requires understanding how knowledge and expertise are shared and distributed among community members. We explore two forms of knowledge distribution structures, coordination and cooperation, that are central to successful collaboration. We propose a novel method for detecting the coordination of strategic communication among members of politic...

RÉSUMÉ. Cet article présente une description des constructions antithétiques, que l’on a intégrée à une grammaire formelle du français spontané dont l’objectif est d’être finalement utilisée pour le TAL. Ces constructions ont pour caractéristique d’être soumises à des contraintes provenant simultanément de domaines divers (lexique, syntaxe, sémantique et pragmatique). Nous présentons ici une de...

1 The talk will describe an ongoing project (modestly named the Neural Theory of Language) that is attempting to model language behavior in a way that is both neurally plausible and computationally practical. The cornerstone of the effort is a formalism called Embodied Construction Grammar (ECG). I will describe the formalism, a robust semantic parser based on it, and a variety of applications ...

In Construction Grammar, grammatical patterns are conventional pairings of form and meaning that are analogous to words. This article contrasts Construction Grammar with competing syntactic theories that are based on universal constraints and the projection properties of words. It reviews arguments for construction-based syntax derived from the following linguistic phenomena: semantic and synta...

Construction grammar, or constructionist approaches more generally, emphasize the function of particular constructions as well as their formal properties. Constructions vary in their degree of generality, from words to idioms to more abstract patterns such as argument structure constructions, topicalization, and passive. There is also no division drawn between semantics and pragmatics, as all c...

verb system and its construction are two of the most important issues in the grammar of middle iranian languages. comparing the construction of verbs in middle iranian languages and dialects reveals their relation with old iranian languages. the aim of this research therefore is first to review the construction of verbs in bactrian as one of the eastern middle iranian languages and second to fi...
