  • Linguistic resources
  • Part-of-speech tagging
  • Statistical language modeling (N-grams and Hidden Markov Models)
  • Robust parsing techniques, probabilistic context-free grammars

Aims

At the end of this learning unit, the student is able to :

1

Given the learning outcomes of the "Master in Computer Science and Engineering" program, this course contributes to the development, acquisition and evaluation of the following learning outcomes:

  • INFO1.1-3
  • INFO2.3-4
  • INFO5.3-5
  • INFO6.1, INFO6.4

Given the learning outcomes of the "Master [120] in Computer Science" program, this course contributes to the development, acquisition and evaluation of the following learning outcomes:

  • SINF1.M4
  • SINF2.3-4
  • SINF5.3-5
  • SINF6.1, SINF6.4

Students completing successfully this course should be able to

  • describe the fundamental concepts of natural language modeling
  • master the methodology of using linguistic resources (corpora, dictionaries, semantic networks, etc) and make an argued choice between various linguistic resources
  • apply in a relevant way statistical language modeling techniques
  • develop linguistic engineering applications

Students will have developed skills and operational methodology. In particular, they have developed their ability to

  • integrate a multidisciplinary approach to the edge between computer science and linguistics, using wisely the terminology and tools of one or the other discipline,
  • manage the time available to complete mini-projects,
  • manipulate and exploit large amounts of data.
