Audiovisual and Multimedia Section (AVMS) and Cataloguing Section (CATS)

IFLA SNGO News Desk :: The Audiovisual and Multimedia Section (AVMS) and the Cataloguing Section (CATS) invite proposals for papers to be presented at the World Library and Information Congress (WLIC) in Singapore, August 17th-23th August 2013.

The cataloguing codes for motion pictures are traditionally based on the cataloguing code for text. They have as their goal to describe a manifestation as a whole: a unit which can be purchased or borrowed. At the same time digitised collections of audiovisual materials are growing fast worldwide and the amount of versions make it even more interesting indexing the content including activities such as providing intellectual access to individual film sequences and shots.

The vast quantities of materials available are making only manually handling unthinkable. Innovative indexing methods for audiovisual materials such as content-based image retrieval (CBIR) also complement text-based indexing by querying and retrieving images and videos by content. CBIR solutions carry out tasks such as identifying objects and faces in images, segmenting videos into short sequences and computing features describing colour, texture, shape, position or motion information in order to enrich textual metadata. The next generation of systems combines text-based indexing and retrieval with content-based indexing and retrieval to provide the most effective retrieval of images and video.

 Traditional cataloguing takes a macro view of the audiovisual materials – CBIR and voice recognition technologies take a micro view of the audiovisual materials. These two perspectives can complement each other and help the user through the maze of information.
