Music Informatics for Radio Across the GlobE (MIRAGE) MetaCorpus

Overview Welcome to the Music Informatics for Radio Across the GlobE (MIRAGE) MetaCorpus. The current (v1.0) release consists of metadata (e.g., artist name, track title) and musicological features (e.g., instrument list, voice type) for 1 million events streaming on 10,000 internet radio stations across the globe, with 100 events from each station. Users who wish to access, interact with, and/or export metadata from the MIRAGE-MetaCorpus may also visit the MIRAGE online dashboard at the following url: https://mirage-project.org Attribution The current MIRAGE-MetaCorpus is available under a CC4 license.

Reliable -- 'All' Sources Match The first subset ('all' sources) consists of events where the stream description reliably matched with metadata from the WikiData, MusicBrainz, Spotify, and Genius sources (>= .9, normalized edit distance): MIRAGE_reliable_all.csv (139,761) events_reliable_all.csv (139,761) tracks_reliable_all.csv (24,697) artists_reliable_all.csv (6,321) stations_reliable_all.csv (6,604) locations_reliable_all.csv (3,238) Reliable -- 'Core' Sources Match The second subset ('core' sources) consists of events where the stream description reliably matched with metadata from either the WikiData or MusicBrainz sources (>= .9, normalized edit distance): MIRAGE_reliable_core.csv (447,238) events_reliable_core.csv (447,238) tracks_reliable_core.csv (174,136) artists_reliable_core.csv (62,324) stations_reliable_core.csv (9,063) locations_reliable_core.csv (4,031) Contact If you are a copyright owner for any of the metadata that appears in the MIRAGE-MetaCorpus and would like us to remove your metadata, please contact the developer team at the following email address: [e-mail]
