The document discusses a thesis on refining statistical data integration on the web, emphasizing the challenges and solutions in music representation using modern digital formats. It highlights a project, midi2rdf, which facilitates lossless conversion between MIDI and RDF, creating a linked data representation for musical assets. Additionally, it explores applications of music as a graph, enhancing knowledge graphs through musical representations and navigation.

- 1. ‹#› Het begint met een idee 1 Het begint met een idee Thesis submitted & just approved “Refining Statistical Data on the Web” 60% of time is spent on data preparation Intelligent solutions for statistical data integration on the Web Use case on structured Humanities data Something different! 1 Faculty / department / title presentation WHY THIS TALK?
- 2. Vrije Universiteit Amsterdam Maybe not that different… 2 SEMANTIC WEB AND THE HUMANITIES

- 5. Vrije Universiteit Amsterdam Besides how awesome this is… The jam became global (i.e. de-referenceable URIs from anywhere) rather than local > But any video stream would have been more accurate (for humans) The jam became machine readable > But not all of it Digital music as Linked Data? 5 REPRESENTING MUSIC IN RDF

- 7. Vrije Universiteit Amsterdam Music representation format which is 100% digital > (i.e. leaving nothing to analog signals actual instruments) MIDI (Musical Instrument Digital Interface) > Universal synthesizer interface > Roland (I. Kakehashi), Yamaha, Korg, Kawai (1981) > Digital, fine-grained representation of musical tracks and events > Wide range of controllers and instruments 7 WEEKEND EXPERIMENT
- 10. Vrije Universiteit Amsterdam Music representation format which is > 100% digital (i.e. leaving nothing to analog signals) > Secundary list MIDI (Musical Instrument Digital Interface) > Universal synthesizer interface > Roland (I.

- 11. Vrije Universiteit Amsterdam midi2rdf > Any MIDI to an RDF midi-comptabile representation > All MIDI resources get URIs (can link, be linked, de-referenced) > Music is a graph! rdf2midi > Round trip conversion > Lossless! > MIDI subseteq RDF playrdf.sh > RDF files can be ‘played’ without data loss > Demo 11 LOSSLESS CONVERSION
- 12. Vrije Universiteit Amsterdam Enrichment of musical assets and events in Linked Data > Annotations > Provenance > Links to places, people, events > Music stream = live representation of music on play 12 APPLICATIONS (I)
- 13. Vrije Universiteit Amsterdam Musical representation of knowledge graphs > Just as we care about visualization of knowledge graphs > Linkage of graph resources/properties to things that can be played > Size = pitch > Regularity = harmony (irregularity = dissonance) > Graph musical navigation > Music stream = navigation path 13 APPLICATIONS (II)
