91269 - MULTIMEDIA DATA MANAGEMENT

Conoscenze e abilità da conseguire

The course aims to provide the knowledge and skills necessary for the effective and efficient management of multimedia (MM) data, with particular attention to the problems of MM data representation, MM data retrieval models, and interaction paradigms between the user and the MM system (both for purposes of data presentation and exploration). We first consider architectures of traditional ("standalone") MM systems; then, we concentrate on more complex MM services, by primarily focusing on search engines, social networks and recommendation systems.

Testi/Bibliografia

Education material provided by the teachers (copies of the slides used in the classroom, scientific literature).

Metodi didattici

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.

Provided slides are in english. Fluent spoken and written english is a necessary pre-requisite: all lectures and tutorials will be in english.

Modalità di verifica e valutazione dell'apprendimento

Achievements will be assessed by the means of a final exam. This is based on an analytical assessment of the "expected learning outcomes" described above. In order to properly assess such achievement the examination is composed of an oral exam.

The admission of the students to the final examination is constrained to the upload of the complete solution of the "free" exercise into the dedicated OneDrive folder "MDM", following the instructions provided by the teacher (see the slides of the course presentation for more details).

To participate to the lab programming exam, interested students have to register themselves by exploiting the usual UniBO Web application, called AlmaEsami.

Higher grades will be awarded to students who demonstrate an organic understanding of the subject, a high ability for critical application, and a clear and concise presentation of the contents. To obtain a passing grade, students are required to at least demonstrate a knowledge of the key concepts of the subject, some ability for critical application, and a comprehensible use of technical language. A failing grade will be awarded if the student shows knowledge gaps in key-concepts of the subject, inappropriate use of language, and/or logic failures in the analysis of the subject.

Strumenti a supporto della didattica

Classroom lessons will be held using slides, which will be integrated with the use of the blackboard for the development of exercises.
