Objectives

The course targets text analytics systems and applications to respond to business problems by discovering and presenting knowledge that is otherwise locked in textual form. The main objectives of the course are:

Learning essential techniques, algorithms, and models used in natural language processing.
Understanding of the architectures of typical text analytics applications and of libraries for building them.
Expertise in design, implementation, and evaluation of applications that exploit analysis, interpretation, and transformation of texts.

Exam modalities

Students will be assessed through a written exam and an oral exam. Each student will be evaluated based on their ability to discuss the course content using appropriate terminology and to practically apply natural language processing techniques.

Attending Students

The exam consists of a written test and an oral test. The exam consists of a written test and an oral test. For the written part, attending students can choose between a traditional written exam, with questions on the topics covered in the course, or a group project carried out during the course period, designed to assess the ability to plan and implement a text analysis task agreed upon with the instructor. In both cases, the oral test follows: students who have completed the project are required to present and discuss it, including individual questions to verify each member’s understanding, and all students, regardless of the chosen option, are further examined on the remaining topics of the course.

Non-Attending Students

The exam consists of a written test and an oral test. Non-attending students will be required to answer questions and solve exercises during a written exam.
No materials other than the slides, notebook experimentation, and the selected chapters from the books are required.

Students are required to study the slides, actively work through and experiment with the notebooks, and read the selected chapters from:
