The main goal of the course is to introduce basic types of natural language processing (NLP) applications and to give the students a chance to work with some of those applications in seminars. The course will concern machine translation, machine aided human translation tools, localization tools, information retrieval and extraction, question answering, speech recognition, spelling and grammar checking, generation etc.

Course completion requirements

Last update: doc. RNDr. Vladislav Kuboň, Ph.D. (22.04.2020)

The course requires a continuous work of students in the form of reports describing topics of individual lectures. The reports are required even if a student is not present on the lecture, in such a case (s)he submits a general report on the topic of the missed lecture. A participation is strongly recommended. After submitting all reports, the student obtains a grade based upon the quality of those reports.
