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:

Data Sources

This repository of the MIRAGE-MetaCorpus contains 131 metadata fields from the following open-access sources:

• Radio Garden (RG) -- https://radio.garden
• Natural Earth map data set (NE) -- https://www.naturalearthdata.com/
• Internet Radio Station Stream Encoder (SE)
• Annotator Review (AR)
• Monitoring/Matching Algorithm (MA)
• WikiData (WD) -- https://www.wikidata.org
• MusicBrainz (MB) -- https://musicbrainz.org/

Each event also includes attribution metadata from the following commercial sources:

• Spotify (SP) -- https://open.spotify.com/
• Genius (GE) -- https://genius.com/
• Musixmatch (MX) -- https://www.musixmatch.com/
• YouTube (YT) -- https://www.youtube.com/

MetaData

The metadata reflect information about each event's location (e.g., city, country), station (name, format, url), event (id, local time at station, etc.), artist (name, voice type, etc.), and track (e.g., title, year of release, etc.). The naming syntax for each metadata field consists of the entity (location, station, event, artist, track), data source (RG, NE, etc.), and metadata name (e.g., Latitude, Frequency, etc.).

Data Sets

The MIRAGE-MetaCorpus includes the following datasets:

• MIRAGE.csv -- the complete metacorpus (1 million)
• events.csv -- all event-level metadata (1 million)
• tracks.csv -- all track-level metadata (414,886)
• artists.csv -- all artist-level metadata (259,783)
• stations.csv -- all station-level metadata (10,000)
• locations.csv -- all location-level metadata (4,324)

Subsets of the MIRAGE-MetaCorpus are also available for events with metadata from online music libraries that reliably matched the event's description in the radio station's stream encoder.

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)
