You can get the complete dataset (includes SQLite3, CSV and .onset files, as well as the ground truth data).

The dataset is also provided in three different formats separately:

1. SQLite3 database
2. CSV files
3. Onset files

You can also get the ground truth data (MIDI renditions of the excerpts included in the dataset, in MIDI and .onset formats).

Description

The dataset is managed in three tables:

Songs table

This table contains information about the songs used in the data collection. The fields of the table are:

Field name	Data Type	Description
id	int	Unique ID of the entry
filename	string	Name of the audio file (only useful to the data collection system)
song_title	string	Name of the song
artist	string	Name of the performing artist
year	int	Year the song was recorded
start_time	time	Start time of the audio excerpt used in the data collection
end_time	time	End time of the audio excerpt used in the data collection
song_section	string	Included to help researchers locate the part of the song used in the query. Main Theme (MT) and Chorus (C) distinctions are ambiguous for some songs.

Users table

Contains information about the experiment participants. From the point of view of the data collection process, this table could be named subjects or participants, but from the perspective of a QBT system, they are users.

Field name	Data Type	Description
id	int	Unique ID of the entry
age	int	User reported age
gender	string	User reported gender
listening_habits	float	0--5 range
instrument_training	float	0--5 range
theory_training	float	0--5 range
handedness	int	-1 (left handed), 0 (ambidextrous) or 1 (right handed)
tone_deaf	int	0 means not tone deaf and 1 means tone deaf
arrhythmic	int	0 means not arrhythmic and 1 means arrhythmic
user_id	string	UUID
native_language	string	User reported native language
specific_training	string	List of numbers of years of training for each instrument the user has been trained in.

Tasks table

Each entry in this table corresponds the to data tapped by a user on a single song. There are multiple entries for a single user/song combination, because the collection condition might be different (i.e. tapping from long term memory vs. short term memory).

Field name	Data Type	Description
id	int	Unique ID of the entry
version_number	string	Version of the front end software used to capture the data
song_title	string	Title of the song the user was asked to tap
user_id	string	UUID of the user tapping (see Users table)
session_id	datetime	Date and time of the collection
experimenter_id	string	Identifier of the device used to collect the data
task_order	int	Incremental integer indicating the order of the songs tapped by a single user in a single tapping session (the same number is repeated for the long and short term memory conditions)
device_type	string	Description of the device used for tapping
song_familiarity	float	0--5 range: indicates the reported song familiarity. This value only makes sense for the long term condition (i.e. when with_music field is 0). If with_music is 1, then this field has a value of 0.
with_music	int	0 indicates long term memory tapping and 1 indicates short term memory tapping
audio_helpful	int	1--6 range: number reporting if listening to the song helped. This value only makes sense for the short term condition (i.e. when with_music is 1). If with_music is 0, then this field has a value of 0. Values other than 0 correspond to: Yes - it helped me remember more details of the song Yes - I thought the lyrics were from a different song, but now I know which song it is Yes - I had no idea of the song from just the lyrics, but listening made me recognize it No - I already knew the song really well No - this song is totally unfamiliar, so hearing it once didn’t help Yes - I didn’t know the song at all, but I could tap it out after hearing it
tap_data	string	Comma separated list of tap on times (in seconds)
tap_off_data	string	Comma separated list of tap off times (in seconds)
tap_x_data	string	Comma separated list of of the tap on's x (horizontal) coordinate (in pixels)
tap_y_data	string	Comma separated list of of the tap on's y (vertical) coordinate (in pixels)
tap_off_x_data	string	Comma separated list of of the tap off's x (horizontal) coordinate (in pixels)
tap_off_y_data	string	Comma separated list of of the tap off's y (vertical) coordinate (in pixels)
