“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!

WHY THIS TALK?

Vrije Universiteit Amsterdam

Maybe not that different…

SEMANTIC WEB AND THE HUMANITIES

Vrije Universiteit Amsterdam4

ISWC 2013 JAM SESSION

Jam’s “metadata”

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?

REPRESENTING MUSIC IN RDF

6 Het begint met een idee

HOW DOES A KNOWLEDGE GRAPH SOUND LIKE?

(OR: MUSIC IS A GRAPH)

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

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. Kakehashi), Yamaha, Korg, Kawai (1981)> Digital, fine-grained representation of musical events> Wide range of controllers and instruments

WEEKEND EXPERIMENT

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

LOSSLESS CONVERSION

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)

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
