Description and contextualization of the subject
The main objective of this course is presentation of the main concepts and models for the computational treatment of morphology (regular expressions, finite-state automata etc). The course will center mainly on languages with rich morphology. During the course, the student will use the foma tool, a free and open source tool for finite-state processing. The course also introduces neural sequence-to-sequence (seq2seq) models as applied to morphology using the OpenNMT tool.Teaching staff

Learning outcomes of the subject
- Identify and solve problems that can be tackled using restricted computational models (automata) or alternative ones (intelligent systems).- Use automata, grammars and regular expressions to define formal languages.
-To know the existing formalisms to describe the morphology of different languages.
- Implement an application of the area of morphology (morphological analyzer, spell checker etc.) using the available tools.
Ordinary call: orientations and renunciation
Ordinary call:The assignments in exercise mode correspond mostly to the formal language part (50% of the final grade). Students who demonstrate that they have already completed this part in their previous studies may be exempted from attending class and doing the exercises and to obtain this part of the grade they will do a practical assignment with the corresponding report that they will present in class.
The project is related to the morphology part (50% of the final grade).
- Class assignments (50%): exercises, notes, ...
- Project (50%): Implementation of a practical project proposed by the teacher
Extraordinary call: orientations and renunciation
Extraordinary call:- Final exam (100%) with theoretical and practical exercices
