  • Linguistics engineering applications such as spell or syntax checking software, POS tagging, document indexing and retrieval, text categorization
Aims

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.

The contribution of this Teaching Unit to the development and command of the skills and learning outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled “Programmes/courses offering this Teaching Unit”.
