Audio Set Ontology

v1 2017-03-06

The file ontology.json contains the current definition ofthe AudioSet ontology, a hierarchicalset of audio event classes.

The json file describes a list of sound entity objects. Each object containsthe fields:

id: The machine identifier for this class, a short sequence like/m/0dgw9r. Where possible, these are based on Knowledge Graph IDs,which were originally used inFreebase.
name: The Display Name that refers to the class. Should be unique andunambiguous. Several classes have one or more synonyms included in theirdisplay names, for example "Male speech, man speaking".
description: A description of the class in a few lines.
citation_uri: A pointer to any text used as the basis for thedescription. Frequently points to a Wikipedia page.
positive_examples: A list of compact URLs to segments within YouTube filesthat provide confirmed positive examples of this class. Each entry is ofthe formyoutu.be/8uI9H5jGRV8?start=30&end=40, meaning the example is the10 seconds starting 30 seconds in to the the YouTube video whose ID is8uI9H5jGRV8.
child_ids: A list of the id fields for any classes that children of thisclass in the class hierarchy.
restrictions: A list that can include the following values:
- abstract for a class that is principally a container within thehierarchy, but will not have any explicit examples for itself. "Humanvoice" is an abstract class. Abstract classes will always have children.
- blacklist for classes that have been excluded from rating for the timebeing. These are classes that we found were too difficult for raters tomark reliably, or for which we had too much trouble finding candidates, orwhich we decided to drop from labeling for some other reason.
