The course unit stresses a case study approach in order to ensure the acquisition of theoretical aspects and practical application (Elementary mathematics tools, propabilities and statistics; and Python programming, both for beginners and advanced users) 801 Machine Learning and Semantic Web: This course takes on the fundamental principles of Machine Learning, of data mining and knowledge extraction. All the notions are illustrated through practical applications on real data (Machine learning theory and Web Semantics) 901 Deep Learning and Data Mining: The objective of this course unit is to acquire machine learning tools, mainly deep neural networks and factorisation matrices, to be able to manipulate these tools when considering practical applications (tweets, traces of e-learning), as well as to expand the students' knowledge in semantic web and the extensions of analysis of formal concepts for textual and relational data processing (Neural Networks, Deep Neural Networks; Data mining (structured data and text); and Collaborative filtering) 702 Design and Acquisition of corpus: This course aims to introduce techniques of construction, structuring, annotating and archival of textual oral or multimodal corpora, which play an essential role in the analysis of the structure of spoken and written language, and on the other hand in the training and evaluation of NLP algorithms. This subject is complex as it is necessary that (1) the corpora be restricted to a reasonable size in order to guarantee the proper collection of corresponding data and that (2) this data sufficiently represents the phenomena studied (Written Corpora; and Spoken Corpora). 802 Formal Tools: This course unit is dedicate to the introduction to theoretical frameworks and logic used in symbolic approaches to the modeling of language. It consists of mathematical logic and of formal languages. The objective is to familiarize the students with these formal models, their properties, the demonstration techniques associated with them, and the notions of calculability and complexity. 902 Text and Speech Processing: Automatic processing of texts and speeches involves different methods of machine learning. This class will introduce these methods and illustrate their use through examples and practical application using tools developed (Speech processing, Processing Textual Data, Terminology and ontology). storage, cleaning, visualisation and analysis of data. We give a practical introduction to the tools and software libraries which allows the processing of data. We combine theoretical sessions with programming exercises which allows students to put into practice the software and concepts taught during the course. 903 Natural Language and Discourse: This course unit gathers courses which deal with discursive and semantic processing of language (Application to texts; Computational semantics; and Discourse and Dialog modelling) 704 Linguistics for NLP-1: This course takes on one hand the fundamental elements of NLP and on the other hand the phonological and morphological elements, which are studied through a language sciences based approach (Methods for Natural Language Processing; Phonology; and Morphology) 804 Linguistics for NLP-2: This course takes up where the previous teachings of linguistics left off, wherein the content and methodologies of the courses are, however, independent from these prior teachings. The courses are concentrated on syntax and semantics, as well as lexicology. In this context, the focus is put on the question of formalisation of linguistic rules (Lexicology: lexical units and phraseology; Syntax; and Semantics) 904 Lexicon and Grammars for NLP: This course introduces advanced tools for the computational modeling of different types of linguistic information which describe lexical units (lexical resources) or the rules of organisation of larger units (grammar) (Diachronic and synchronic lexicology; Lexical resources; and Syntactic framework) 705 This course unit is composed of the first part of the year-long supervised project (which will be finalized in the second semester), as well as language classes. The project consists of group work (in pairs), which is supervised by researchers, in which the students will carry out the bibliographic part of the final report. Language classes will allow non-anglophone students to become more familiar with scientific english, the language in which all courses are conducted, whereas the french classes will facilitate non-francophone students' social and cultural integration. The course allows students to test their first skills acquired during the semester while synthesizing the different research issues concerned by a more open research topic. Students are evaluated on the acquisition of targeted skills, identified for the Sc. Master. 805 This course unit is made up of language classes as well as the second part of the yearlong supervised project (UE 705) which is finalized during the second semester. The second part of the year-long project begins by following through with the procedure introduced in the first semester groupwork, and leads up to the presentation at the end of the year, explaining the implementation of the project, which puts to test all of the skills the student acquires during the first year of the program. The language classes allow students to become more comfortable with the knowledge of scientific english. 905 Projects and Foreign Language: This course unit gathers many teaching including the project and language classes (Software project; Law and ethics; Research methods; Professional integration; Foreign language courses (French or English)) \u2022 first experiments to highlight the possibility of getting results with few developments with two labs: one on FastText ) and the one on Scikit Learn (Pedregosa et al., 2011) , are proposed.
