Génie logiciel pour le génie linguiciel

Abstract : The aim of this thesis is the study of various modern engineering techniques which can be used for the development of Natural Language Processing systems. The first part presents the state of the art in NLP concerning Specialised Languages for Linguistic Programming. We identify integrability, genericity and extensibility as the most crucial properties of NLP systems. The definition of an object model (LEAF) and the enhancement of an architural model (WhiteBoard) are the first two answers to integrability. A first approach to genericity and extensibility is also provided by a reengineering experiment of the LT language. The second part gives a thorough account of the problems linked to genericity and exemplifies them with the definition of an original linguistic representation language (DECOR). This language can be made both generic and dynamic by the introduction of internal and external protocols. The third part concerns the reengineering of two specialized langages (ATEF and ROBRA). This experiment allows us to introduce a good extensibility in the engines of these languages, using object and protocol oriented programming techniques. A common question to these three parts comes up with the identification of the limits and difficulties concerning the journey to integrability, genericity and extensibility. These obstacles come mainly from of the increasing complexity of the appropriate protocols, which may easily cause the developer to lose control over the implementation.
