· Modelling text data and keywords – inverted index, thesauri for query expansion, precision/recall
· Metadata for multimedia – e.g. the Dublin Core Metadata Set, MPEG-7·
· Key concepts: user information needs, modelling, media access functions – retrieval and browsing, multimedia content and different levels of abstraction·
· Current applications, including personal media collections, organisation-wide media archives, web-based search engines, and virtual worlds: considering exemplar applications such as Flickr, YouTube and Second Life.
· Modelling the content of images – content independent, content-dependent, content-descriptive metadata; case studies of image retrieval systems·
· Modelling the content of temporal media (video and audio) – data models with discrete, overlapping and hierarchical intervals; formal descriptions of objects, events and temporal relationships between events; the MPEG standards·
· Combining media items into synchronised presentations using the Synchronised Multimedia Integration Language (SMIL)·
