Annotation phase detail

Terminology

Annotation Phase

A phase characterises the work carried out on a campaign. There are two types of phase:

"Annotation": This type of phase is used to make an initial annotation of the campaign, based on empty spectrograms. This type of phase can also be used to import external annotations, for example from automatic detectors.
"Verification": Verification phases are used to validate/invalidate annotations made in the “Annotation” phase. If a user is assigned to both phases, he will not be able to validate his own annotations.

The two phases can take place simultaneously.

Annotation Campaign

A campaign refers to the annotations of a dataset with a defined set of labels and tasks. Each campaign is defined by a name, a dataset and spectrogram configurations. A campaign is made up of phases.

Label

A label defining a specific sound. It can define sounds of interest such as the species and their vocalization or a boat passage.

It can be grouped into a Label set

Confidence

An indicator that represents the level of confidence the annotator has in each annotation. This indicator can be customized, it can be a Boolean value or a level from 0 to 3 for instance.

It can be grouped into a Confidence set

Once you are on the campaign detail, you can select the phase tab you want to access.

The page shows the dataset files you were assigned for annotation. You can search a specific file or only show non submitted files or only files with annotations. You can also directly resume annotation, this will take you to the first unsubmitted file.

The file table contains the following columns:

Column	Phase	Description
Filename	all	Name of the file
Date	all	Start of the recording
Duration	all	Duration of the recording
Annotations	Annotation	Number of annotations you created
Annotations to check	Verification	Number of annotations from the "Annotation phase" that need to be checked
Validated annotations	Verification	Number of annotations you validated
Status	all	Either you submitted your work on the file
Access	all	A direct link to access the annotator
