Learning outcomes

The course aims at providing the students with the knowledge and skills needed for achieving an effective and efficient management of documentary databases.
Particular attention is devoted to the documents representation, their indexing techniques, and models of queries (together with metrics for the evaluation of
the quality of the provided results), starting from traditional documents and then continuing with the most complex multimedia documents.

Readings/Bibliography

During the course, the teacher will provide the students with educational material in the form of slides and relevant scientific literature.

Teaching methods

Course lectures are in "traditional" classrooms and exploit the slides. Several use cases will be presented in order to show how such information technologies can be profitably applied in a number of real applications.

Assessment methods

The exam evaluation consists of a oral examination. To participate to the lab programming exam, interested students have to register themselves by exploiting the usual UniBO Web application, called AlmaEsami.

Teaching tools

In traditional classrooms, the course lectures will make extensive usage of slides.
