Description and contextualization of the subject

The main aim of this course is to show the importance of linguistic resources (databases, knowledge bases and corpora tagged at different linguistic levels) and their appropriate design so that it is possible to learn automatically from them, feed them back with the new information, and evaluate them quantitatively and qualitatively. Besides, the multilingual and interlinguistic issues are emphasized. A practical approach to learn the contents is followed in this course.
