[show abstract] [hide abstract]
ABSTRACT: The National Digital Data Archive (NDDA) is an ongoing initiative of the Hungarian government that makes Hungary’s national cultural assets available in digital form. The NDDA features a decentralized OAI-based network of archives and service providers facilitating discovery and access to digitized objects. Authors’ participation in the project is described including the implementation of an NDDA service provider. This service provider is connected with an RDF-based metadata schema registry enabling the service to automatically adapt to the metadata schemas defined within the NDDA.09/2005: pages 314-322; -

Article: Tillarom: an AJAX based folk song search and retrieval system with gesture interface based on kodály hand
[show abstract] [hide abstract]
ABSTRACT: A digital folk song search and retrieval system with a hand gesture based interface is presented. Tillarom is a comprehensive collection of original Hungarian folk songs recorded using different technologies such as phonographs and/or stereo DAT cassettes. This digital archive contains professional quality metadata records as well as MIDI recordings for presenting the different types of clustered folk songs. An AJAX based search and retrieval interface was developed that can be used together with optically recognized Kodály's hand signs to formulate queries through a web browser. The appearance based recognition of hand gestures utilizes contour analysis and SVM based classification. We evaluated the performance of the recognition of hand signs and investigated the main problems of their usage in our system.
