Path parameters

idinteger required

Response

Projects list

annotator_evaluation_enabledboolean

Enable annotator evaluation for the project

colorstring nullable
config_has_control_tagsboolean required

Flag to detect is project ready for labeling

config_suitable_for_bulk_annotationboolean required

Flag to detect is project ready for bulk annotation

control_weightsobject nullable

Dict of weights for each control tag in metric calculation. Keys are control tag names from the labeling config. At least one tag must have a non-zero overall weight.

created_atstring date-time required
descriptionstring nullable

Project description

enable_empty_annotationboolean

Allow annotators to submit empty annotations

evaluate_predictions_automaticallyboolean

Retrieve and display predictions when loading a task

expert_instructionstring nullable

Labeling instructions in HTML format

finished_task_numberinteger required

Finished tasks

ground_truth_numberinteger required

Honeypot annotation number in project

idinteger required
is_draftboolean

Whether or not the project is in the middle of being created

is_publishedboolean

Whether or not the project is published to annotators

label_configstring nullable

Label config in XML format. See more about it in documentation

maximum_annotationsinteger

Maximum number of annotations for one task. If the number of annotations per task is equal or greater to this value, the task is completed (is_labeled=True)

min_annotations_to_start_traininginteger

Minimum number of completed tasks after which model training is started

model_versionstring nullable

Machine learning model version

num_tasks_with_annotationsinteger required

Tasks with annotations count

organizationinteger nullable
overlap_cohort_percentageinteger
parsed_label_configobject required

JSON-formatted labeling configuration

pinned_atstring date-time nullable

Pinned date and time

queue_doneinteger required
queue_totalinteger required
reveal_preannotations_interactivelyboolean

Reveal pre-annotations interactively

sampling'Sequential sampling' | 'Uniform sampling' | 'Uncertainty sampling'
  • Sequential sampling - Tasks are ordered by Data manager ordering
  • Uniform sampling - Tasks are chosen randomly
  • Uncertainty sampling - Tasks are chosen according to model uncertainty scores (active learning mode)
show_annotation_historyboolean

Show annotation history to annotator

show_collab_predictionsboolean

If set, the annotator can view model predictions

show_ground_truth_firstboolean

Onboarding mode (true): show ground truth tasks first in the labeling stream

show_instructionboolean

Show instructions to the annotator before they start

show_overlap_firstboolean
show_skip_buttonboolean

Show a skip button in interface and allow annotators to skip the task

skip_queue'REQUEUE_FOR_ME' | 'REQUEUE_FOR_OTHERS' | 'IGNORE_SKIPPED'
  • REQUEUE_FOR_ME - Requeue for me
  • REQUEUE_FOR_OTHERS - Requeue for others
  • IGNORE_SKIPPED - Ignore skipped
skipped_annotations_numberinteger required

Skipped by collaborators annotation number in project

start_training_on_annotation_updateboolean required

Start model training after any annotations are submitted or updated

statestring required

total_predictions_numberinteger required

Total predictions number in project including skipped_annotations_number, ground_truth_number, and useful_annotation_number.

useful_annotation_numberinteger required

Useful annotation number in project not including skipped_annotations_number and ground_truth_number. Total annotations = annotation_number + skipped_annotations_number + ground_truth_number
