The Computational Linguistics course is taught by Raffaella Bernardi (UniTN)
Classes are on Mondays and Wednesdays at 13:00-15:00 and on Thursdays at 10:30-12:30. Detailed schedule
Please, note there are no classes on the 2th of October and on the 13rd of November
For updated information, see the online time-table
Information about the final exam
The exam will consist of two parts each contributing the 50% of the total mark:
- written exercises on Syntax, Semantics and their interface
- written report on a topic selected among those presented in class. The report can be either a project proposal based on a literature review or the report on a project based on a literature review. The report has to be written in LaTeX.
Students of the Text Processing course will do one of the two parts at their choice. They have to inform the lecturer of their choice at least two months before the exam.
Students have to agree on the topic of the report with the lecturer at least one month before the exam.
July Exam The exam will be run using the same format of the winter exam: project (see above) and written exam. The latter will be run using Zoom. The lecturer will send the link to students beforehand. The students will have to turn the webcamera so to let the lecturer see the paper where he/she writes. At the end of the exam, students will send the written exercises to the lecturer by email before leaving the Zoom meeting. Students can leave the meeting only when all students have finished the exam and have sent it to the lecturer.
We will rely on programming skills taught by Luca Ducceschi in the course Computational Skills for Text Analysis (first semester). Students are highly reccomended to attend it, in particular if they lack a computational background. My course is complementary to Carlo Strapparava's course on Human Language Technologies (second semester). The Formal Semantic part will be presented in depth in Roberto Zamparelli's course on Logical Structures of Natural Language.
