PRESENTAZIONE

The Natural Language Processing course provides an introduction to the most challenging issues in processing natural languages, driven by the three layers of syntax, semantics, pragmatics; the most recent applications of natural language processing tools are discussed, including the design and development of ontologies and of chatbots. 

OBIETTIVI E CONTENUTI

OBIETTIVI FORMATIVI

Learning how to process and represent natural language, and the main software components of a system able to understand natural language.

OBIETTIVI FORMATIVI (DETTAGLIO) E RISULTATI DI APPRENDIMENTO

After the course students will be able to use existing tools and design and implement new ones for solving Natural Language Processing problems at the syntactic and semantic level. They will also be able to design and implement a chatbot using one of the most widespread chatbot languages. 

MODALITA' DIDATTICHE

Traditional: frontal lessons and laboratories

ESAMI

MODALITA' D'ESAME

The exam will consist in a quiz, a written part (traditional open/closed questions, exercises) plus an individual project (requiring about 1 man/week to be completed).

MODALITA' DI ACCERTAMENTO

The acquisition of the skills foreseen by this course will be assessed via the quiz and written exam + the project which have been carefully designed to allow the teachers to verify whether a student is actually able to design and implement a tool solving some (simplified) NLP problem and to understand, present and discuss in a critical way the most challenging issues raised by its development.
