Folksonomy

The list of adjective-noun and verb-noun pairs from the previous section was used to query and download audio recordings from freesound.org. The website has the largest archive of sounds with around 230,000 recordings, which allowed us to collect audio in a large-scale. Moreover, the website has been successfully employed before to create popular datasets (ESC-50, Freefield, UrbanSounds) [13], [34], [14]. Other websites such as soundcloud.com and findsounds.com were considered but not employed because they either contained mainly music or had less sound recordings in their archives.

The freesound.org website is a collaborative repository of audio where users upload recordings and write tags to describe their content. This folksonomy-like structure of repository has the benefit of reflecting the popular and long-tailed combinations of tags. In this manner we can observe what are the socially-relevant adjectives, verbs and nouns.
