In this paper, we tackle the issue of multiplicity of meaning in derivation using Frame Semantics and eXtensible MetaGrammar (XMG). We use corpus extracted data to identify the range of readings -al derivatives exhibit and identify prominent constraints on the types of situations and entities -al targets. These constraints have the form of type con...

Multiword expressions (MWEs) exhibit both regular and idiosyncratic properties. Their idiosyncrasy requires lexical encoding in parallel with their component words. Their (at times intricate) regularity, on the other hand, calls for means of flexible factorization to avoid redundant descriptions of shared properties. However, so far, non-redundant...

This paper introduces XMG 2, a modular and extensible tool for various linguistic description tasks. Based on the notion of meta-compilation (that is, compilation of compilers), XMG 2 reuses the main concepts underlying XMG, namely logic programming and constraint satisfaction, to generate on-demand XMG-like compilers by assembling elementary units...

This work presents results on the integration of frame-based representations into the framework of eXtensible MetaGrammar (XMG). Originally XMG allowed for the description of tree-based syntactic structures and underspecified representations of predicate-logical formulae, but the representation of frames as a sort of typed feature structure, partic...

In this article we propose to model the derivational morphology of Arabic using the metagrammatical framework of XMG. We demonstrate that treating abstract roots and patterns as semantically underspecified atomic morphemes offers an elegant way to account for the interaction between morphology and semantics.

The work presented in this thesis aim at facilitating the development of resources for na- tural language processing. Resources of this type take different forms, because of the existence of several levels of linguistic description (syntax, morphology, semantics, . . . ) and of several forma- lisms proposed for the description of natural languages...

XMG (extensible metagrammar) is a metagrammar compiler which has already been used for the design of large scale tree adjoining grammars and interaction grammars. Due to the heterogeneity in the field of grammar development (different grammar formalisms, different languages, etc), a particularly interesting aspect to explore is modularity. In this...

This paper aims to show that metagrammars are not only suited for the development of large scale grammars for natural languages, but can also deal with other types of resources. We give the example of some elementary music phenomena, that can be quite naturally described within the modular scope offered by eXtensible MetaGrammar.
