Modular Generation of Formal Grammars
The work presented in my thesis aims at facilitating the development of resources for natural language processing. Resources of this type take different forms, because of the existence of several levels of linguistic description (syntax, morphology, semantics, etc) and of several formalisms proposed for the description of natural languages at each one of these levels. The formalisms featuring different types of structures, a unique description language is not enough: it is necessary to create a domain specific language (or DSL) for every formalism, and to implement a new tool which uses this language, which is a long and complex task.
For this reason, I propose in this thesis a method to assemble in a modular way development frameworks specific to tasks of linguistic resource generation. The frameworks assembled thanks to a method I developed in cooperation with my advisors Denys Duchier and Yannick Parmentier are based on the fundamental concepts of the XMG (eXtensible MetaGrammar) approach, allowing the generation of tree based grammars.
The method is based on the assembling of a description language from reusable bricks and according to a unique specification file. The totality of the processing chain for the DSL is automatically assembled thanks to the same specification.
In a first run, this approach was validated by recreating the XMG tool from elementary bricks. Collaborations with linguists also lead to assemblies of compilers allowing the description of morphology and semantics.
