musoW

The catalogue of music data on the web

Type: Demo

musoW is currently the most comprehensive catalogue of online music data sources. In Polifonia we collaboratively expand the dataset with the help of music enthusiasts, professionals and scholars, who can contribute and explore the collection via user-friendly interfaces. musoW dataset is offered as a Linked Open Dataset complying with schema.org, and the web application is based on CLEF.

CLEF

Crowdsourcing Linked open data Entities via web Form

CLEF is a customisable web environment for crowdsourcing data and serve them as Linked Open Data. The platform helps users to populate a catalogue of web resources of any kind, and provides them some utilities to ensure data quality (e.g. autocompletion powered by external data sources such as Wikidata and geonames) and preservation (e.g. the long-term preservation of surveyed resources via Internet Archive). In Polifonia, we use CLEF to support musoW, the survey of music data sources on the web (see demo).

LHARP

Local Harmonic Agreement based on Recurrent Patterns

LHARP is a local method for harmonic similarity that emphasises shared repeated patterns among symbolic chord sequences, to accommodate a wide set of applications. Compared to other methods, the local nature of LHARP enables more explorative studies, as it can unveil and establish links when local harmonic patterns are found repeated in both sequences, while retaining global information to a lesser extent. Here, we demo “The Harmonic Network” — a computational tool allowing users to explore music collections by visualising LHARP (harmonic) similarities among tracks, and interacting with the resulting graph to discover nontrivial relationships among authors, composers, and pieces.

ChoCo

The Chord Corpus

Type: Knowledge graph / Ontology

ChoCo is a large dataset for musical harmony knowledge graphs. The corpus integrates more than 20,000 human-made, high-quality harmonic annotations from 18 highly heterogeneous chord datasets. The annotations are rich in provenance data (e.g. metadata of the annotated work, authors of annotations, identifiers, etc.) and refer to both symbolic music notation and audio recordings. By leveraging the Polifonia Ontology Network, ChoCo enriches, extends, and standardises these annotations under the JAMS definition – to provide fine-grained semantic descriptions of chords, opportunities for chord interoperability, and 3,000+ links to external datasets.
