Course contents Learning outcomes § The course aims to provide the students with all necessary knowledge and skills to deal with the effective and efficient management of “non-conventional” data types, notably multimedia (MM) data (e.g., textual documents, still images, videos, sound, audio/visual streams, etc.); the final goal is to find, within very large collections, namely “ Big Data ”, those objects that are better suited to fulfill the information needs of non-expert users § We pay special attention to problems of MM data modeling/ 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 recommender systems I. Bartolini Multimedia Data Management M 5
Course contents Topics at a glance § Multimedia data and data types classification § Textual documents: the easiest case of multimedia data § Multimedia data content representations § Automatic techniques for MM data semantic annotations § Efficient and effective techniques for multimedia data retrieval, browsing, and visualization § Multimedia data on the Web !Each lecture is enriched by practical examples , use cases , demos , and exercises … J I. Bartolini Multimedia Data Management M 6
Main goal in one pic! § Facilitate and improve the “access” to very large multimedia data collections for general users, conjunctively exploiting: § low level features (e.g., color distribution of a video key frame) Models, § semi-automatically provided annotations Algorithms, Interfaces § “dedicated users” manually provided meta-data Archivio Storico Fiat Cineteca Archivio Artistico § Das Cabinet des Dr. Caligari § La Gioconda § Trimotore Fiat G212 § Data: 1920 § Sito: Museo Louvre, Parigi § Data: 1947 Collezione: Tema di cultura § Nazione: Germania Secolo: XVI § § § Regista: Robert Wiene § Autore: Leonardo da Vinci industriale Tipologia: Immagine § Genere: Horror Periodo: Rinascimento § § § Espressionismo, Ipnosi, § Data: 1503 § Aereo, Motore, Ali Sonnambulismo Dipinto, Ritratto, Sorriso § I.

Bartolini Multimedia Data Management M 11
Readings/Bibliography § Education material provided by the teacher (copies of the slides used in the classroom, scientific literature, etc.) For any further additional information, recommended books are: § Candan, Sapino. “ Data Management for Multimedia Retrieval ”, Cambridge, 2010. ISBN: 978-0-521-88739-7 § Zhang, Zhang. “ Multimedia Data Mining: A Systematic Introduction to Concepts and Theory ”, Chapman and Hall/CRC, 2008. ISBN: 9781584889663 § Chapman & Chapman. “ Digital Multimedia ”, Wiley & Sons Ltd, 2009. ISBN: 13 978-0-470-51216-6 § Colace, De Santo, Moscato, Picariello, Schreiber, Tanca. “ Data Management for Pervasive Systems ”, Springer, 2015. ISBN: 978-3-319- 20061-3 I. Bartolini Multimedia Data Management M 12 12
Teaching methods § Most course lectures are in “traditional” classrooms and exploit the slides § Real use cases (+ relative demos) are also proposed and discussed based on open-source software libraries and frameworks I. Bartolini Multimedia Data Management M 13 13
Assessment methods § The exam evaluation consists of an oral examination § To participate to the exam, interested students have to register themselves by exploiting the usual UniBO Web application, called AlmaEsami § The students can also arrange with the teacher a “Project work” of Multimedia Data Management M based on their own preferences or suggested topics… more details on this in few minutes… J § In this case, the oral examination can be taken conjunctly with the project presentation I. Bartolini Multimedia Data Management M 14 14
Examination sessions § Six examination sessions per year divided as follows: § three sessions before the summer § starting from September, at the request of the students I. Bartolini Multimedia Data Management M 15 15
Project work details (1) § The project activity aims to apply the notions and skills acquired during the course by developing a project § The project consists in the concrete resolution of a problem concerning the management of multimedia data § The topic of the project can be proposed either by the teacher and the student § Usually a scientific paper is considered as the base for the development of a new multimedia data management algorithm and/or infrastructure and/or service and/or interface § however, everything that “looks interesting” is allowed to be candidate! J § Once you start your project work, the development stages are verified by the teacher with periodical meetings I. Bartolini Multimedia Data Management M 16 16
Project work details (2) § The final evaluation consists of a Power Point presentation integrated by a project demo § According to students’ preferences, the project presentation can be taken conjunctly with the final course oral examination § During the development phase of the project, students can profitably use/extend existing software libraries, such as § Open-source Multimedia libraries and architectures § Multimedia frameworks, e.g., § Windsurf, for the management of large image collections § Shiatsu, for the management of large video databases § RAM 3 S, for the real-time analysis of massive multimedia streams § … developed within the Multimedia Database Group @ DISI ( http://www-db.disi.unibo.it/MMDBGroup/ ) § Augmented reality environments for immersive 3D applications I.
