We presented a demo and a poster at the 10th Extended Semantic Web Conference (ESWC) in Montpellier, France (May 26 - 30, 2013). The conference took place in Corum, a building that houses a large conference centre and an opera house in the centre of the city. The poster and demo session was scheduled on the evening of the first day of the main conference program on Tuesday, May 28th. There were 20 posters and 24 demos in total accepted to the program, all presented in the large foyer area of Corum, which made for a rather vibrant atmosphere.
Our presentation combined the demo and a poster in the same space. The poster outlines the structure of the Audio Feature Ontology (AFO) framework, while the demo provided a practical application of the framework in a feature extraction workflow, using the Sonic Annotator Web Application (SAWA) online interface. Presenting the demo and the poster together in the same space allowed us to mutually complement both, the poster providing the theoretical background and conceptual framework to the practical application of annotating the feature extraction process in SAWA.
There was a steady flow of interested delegates over the two and half hour session. Since the majority of the attendees were Semantic Web researchers who are generally unfamiliar with our specialist subject of music information retrieval, our presentation initially had to introduce the idea of audio feature extraction, before embarking on a more specific introduction of the ontology framework and SAWA.
