Book Description
This is the first comprehensive overview of computational approaches to Arabic morphology. The subtitle aims to reflect that widely different computational approaches to the Arabic morphological system have been proposed. The book provides a showcase of the most advanced language technologies applied to one of the most vexing problems in linguistics. It covers knowledge-based and empirical-based approaches.

Book Description
This landmark volume offers an introduction to the field of teaching Arabic as a foreign or second language. Recent growth in student numbers and the demand for new and more diverse Arabic language programs of instruction have created a need that has outpaced the ability of teacher preparation programs to provide sufficient numbers of well-qualified professional teachers at the level of skill required. Arabic language program administrators anticipate that the increases in enrollment will continue into the next decades. More resources and more varied materials are seriously needed in Arabic teacher education and training. The goal of this Handbook is to address that need. The most significant feature of this volume is its pioneer role in approaching the field of Arabic language teaching from many different perspectives. It offers readers the opportunity to consider the role, status, and content of Arabic language teaching in the world today. The Handbook is intended as a resource to be used in building Arabic language and teacher education programs and in guiding future academic research. Thirty-four chapters authored by leaders in the field are organized around nine themes: *Background of Arabic Language Teaching; *Contexts of Arabic Language Teaching; *Communicative Competence in Arabic; *The Learners; *Assessment; *Technology Applications; *Curriculum Development, Design, and Models; *Arabic Language Program Administration and Management; and *Planning for the Future of Arabic Language Learning and Teaching. The Handbook for Arabic Language Teaching Professionals in the 21st Century will benefit and be welcomed by Arabic language teacher educators and trainers, administrators, graduate students, and scholars around the world. It is intended to create dialogue among scholars and professionals in the field and in related fields--dialogue that will contribute to creating new models for curriculum and course design, materials and assessment tools, and ultimately, better instructional effectiveness for all Arabic learners everywhere, in both Arabic-speaking and non-Arabic speaking countries.

Book Description
La question de l'enseignement du lexique est essentielle pour l'apprentissage d'une langue étrangère, comme c'est le cas du français. Cependant, les méthodes d'enseignement existantes valorisent davantage l'approche grammaticale ou socio-linguistique.Notre recherche se propose d'étudier le rôle de l'enseignement de la morphologie dérivationnelle de la langue cible chez un public d'apprenants universitaires libyens en troisième année de licence.Après avoir défini dans le cadre théorique les particularités des langues arabe et française en ce qui concerne la construction dérivée des mots du lexique, nous analyserons une série de tâches données à ces apprenants portant sur la transformation de mots en différentes classes grammaticales.L'analyse de la réalisation d'une série de quatre tâches par soixante apprenants nous permettra de proposer une présentation des différents types d'apprentissage en FLE et les façons d'enseigner le lexique. Pour ce faire, nous interrogerons dans un premier temps les préconisations des programmes de l'école française en matière de progressivité et de contenus, puis nous les comparerons avec les contenus en cours de FLE. Enfin, notre thèse s'achèvera par un premier ensemble de pistes didactiques que nous comptons compléter par des recherches ultérieures.

Book Description
Cette thèse porte sur l'identification des expressions polylexicales, abordée au moyen d'une analyse par transitions. Une expression polylexicale (EP) est une construction linguistique composée de plusieurs éléments dont la combinaison montre une irrégularité à un ou plusieurs niveaux linguistiques. La tâche d'identification d'EPs consiste à annoter en contexte les occurrences d'EPs dans des textes, i.e à détecter les ensembles de tokens formant de telles occurrences. L'analyse par transitions est une approche célèbre qui construit une sortie structurée à partir d'une séquence d'éléments, en appliquant une séquence de «transitions» choisies parmi un ensemble prédéfini, pour construire incrémentalement la sortie. Dans cette thèse, nous proposons un système par transitions dédié à l'identification des EPs au sein de phrases représentées comme des séquences de tokens, et étudions diverses architectures pour le classifieur qui sélectionne les transitions à appliquer, permettant de construire l'analyse de la phrase. La première variante de notre système utilise un classifieur linéaire de type machine à vecteur support. Les variantes suivantes utilisent des modèles neuronaux: un simple perceptron multicouche, puis des variantes intégrant une ou plusieurs couches récurrentes. Le scénario privilégié est une identification d'EPs n'utilisant pas d'informations syntaxiques, alors même que l'on sait les deux tâches liées. Nous étudions ensuite une approche par apprentissage multitâche, réalisant conjointement l'étiquetage morphosyntaxique, l'identification des EPs par transitions et l'analyse syntaxique en dépendances par transitions. La thèse comporte une partie expérimentale importante. Nous avons d'une part étudié quelles techniques de ré-échantillonnage des données permettent une bonne stabilité de l'apprentissage malgré des initialisations aléatoires. D'autre part, nous avons proposé une méthode de réglage des hyperparamètres de nos modèles par analyse de tendances au sein d'une recherche aléatoire de combinaison d'hyperparamètres. Nous utilisons en effet de manière privilégiée les données des deux compétitions internationales PARSEME des EPs verbales. Nos variantes produisent de très bons résultats, et notamment les scores d'état de l'art pour de nombreuses langues de PARSEME. L'une des variantes s'est classée première pour la plupart des langues de PARSEME 1.0. Pourtant, nos modèles ont des performances faibles sur les EPs non vues à l'apprentissage.

Book Description
Twenty-five languages die each year; at this pace, half the world’s five thousand languages will disappear within the next century. In this timely book, Claude Hagège seeks to make clear the magnitude of the cultural loss represented by the crisis of language death. By focusing on the relationship of language to culture and the world of ideas, Hagège shows how languages are themselves crucial repositories of culture; the traditions, proverbs, and knowledge of our ancestors reside in the language we use. His wide-ranging examination covers all continents and language families to uncover not only how languages die, but also how they can be revitalized—for example in the remarkable case of Hebrew. In a striking metaphor, Hagège likens languages to bonfires of social behavior that leave behind sparks even after they die; from these sparks languages can be rekindled and made to live again.

Book Description
Natural language processing (NLP) went through a profound transformation in the mid-1980s when it shifted to make heavy use of corpora and data-driven techniques to analyze language. Since then, the use of statistical techniques in NLP has evolved in several ways. One such example of evolution took place in the late 1990s or early 2000s, when full-fledged Bayesian machinery was introduced to NLP. This Bayesian approach to NLP has come to accommodate for various shortcomings in the frequentist approach and to enrich it, especially in the unsupervised setting, where statistical learning is done without target prediction examples. We cover the methods and algorithms that are needed to fluently read Bayesian learning papers in NLP and to do research in the area. These methods and algorithms are partially borrowed from both machine learning and statistics and are partially developed "in-house" in NLP. We cover inference techniques such as Markov chain Monte Carlo sampling and variational inference, Bayesian estimation, and nonparametric modeling. We also cover fundamental concepts in Bayesian statistics such as prior distributions, conjugacy, and generative modeling. Finally, we cover some of the fundamental modeling techniques in NLP, such as grammar modeling and their use with Bayesian analysis.
