Course Description

This course explores methods and techniques used in NLP in building and using written corpora. Concepts and notions are introduced such as corpus linguistics and the criteria necessarily taken into account when collecting a corpus (size, variety, etc.) as well as the forms the corpora make take (character encoding, XML, …). Other notions developed include corpus collection from the Web, the use of different formats of documents, and normalisation of badly collected or heterogeneous data.
