| Categories or classification schemes offer ways of navigating
and having higher control over the search and
retrieval of audio content. The MPEG7 standard provides
description mechanisms and ontology management
tools for multimedia documents. We have implemented
a classification scheme for sound effects
management inspired by the MPEG7 standard on top
of an existing lexical network, WordNet. WordNet is a
semantic network that organizes over 100,000 concepts
of the real world with links between them. We
show how to extend WordNet with the concepts of the
specific domain of sound effects. We review some of
the taxonomies to acoustically describe sounds. Mining
legacy metadata from sound effects libraries further supplies us with terms. The extended semantic network
includes the semantic, perceptual, and sound effects
specific terms in an unambiguous way. We show
the usefulness of the approach easing the task for the
librarian and providing higher control on the search
and retrieval for the user. |
