This course offers an in-depth coverage of main basic tasks for Natural Language Processing. We will present fundamental models and tools to approach a variety of Natural Language Processing tasks, ranging from named entity recognition to syntactic processing and document classification. The flow of the course is along two main axis: (1) computational formalisms to describe natural language processes, and (2) statistical and machine learning methods to acquire linguistic models from large data collections and solve specific linguistic tasks

Learn to apply statistical methods for NLP in a practical application
Understand statistical and machine learning techniques applied to NLP
Develop the ability to solve technical problems related to statistical and algorithmic problems in NLP
Understand fundamental methods of Natural Language Processing from a computational perspective
These lectures will present sequence models, an important set of tools that is used for sequential tasks. We will present this in the framework of structured prediction (later in the course we will see that the same framework is used for parsing and translation). We will focus on machine learning aspects, as well as algorithmic aspects. We will give special emphasis to Conditional Random Fields.
Also Deep Learning models will be presented Objectives:42 Contents:
We will present statistical models for syntactic structure, and in general tree structures. The focus will be on probabilistic context-free grammars and dependency grammars, two standard formalisms. We will see relevant algorithms, as well as methods to learn grammars from data based on the structured prediction framework.
Sentence similarity, sentence classification. LSTM. BERT. Sentence embeddings Objectives:42 Contents:
The course will be structured around four different linguistic analysis levels: word level, phrase level, sentence level, and document level. Typical NLP tasks and solutions corresponding to each level will be presented.
The first half of the course is devoted to "classical" statistical and ML approaches. The second half of the course revisits the same levels under a deep learning perspective
Theoretical background and practical exercises will be developed in class.
Finally, students will develop a practical project in teams of two students. The goal of the project is to put into practice the methods learned in class, and learn how the experimental methodology that is used in the NLP field. Students have to identify existing components (i.e. data and tools) that can be used to build a system, and perform experiments in order to perform empirical analysis of some statistical NLP method.
