Podcast Pinpointer: A Multimedia Semantic Web Application

Abstract

In late 2004, a new method of publishing multimedia broadcasts on the Internet became popular called `Podcasting¿. Podcasting incorporates existing feed description formats, namely RSS 2.0, to deliver various enclosed files. This allows users to subscribe to feeds, receiving updates periodically. Originally intended for self- publishing and syndication of audio files, usage of Podcasting for video files has become quite popular. Indeed, thousands of Podcast feeds are now available, reaching a wide range of listeners and viewers. The rapid development of such a technology proves the demand for structured formats of describing multimedia data, facilitating location and retrieval of desirable media for consumers. This paper proposes such a format, using Semantic Web technologies, that has been used in a prototype application for the intelligent location and retrieval of Podcasts.
