# CSA4020 - Multimedia Systems

## Preamble

CSA4020 is a double credit (28-hour) lecture course which is given
to final-year students in the Computer Science track of the B.Sc.
(Hons.) I.T. degree awarded by the University of Malta.
The course is split into 2 parts:

- Information Retrieval (text and multimedia) (approx. 10 lectures)
- Adaptive Hypermedia Systems (approx. 7 lectures)

Please note that although there are only 17 lectures listed, some of
them contain two lectures worth of material.
