AlpacaTag is an open-source web-based data annotation framework for sequence tagging tasks, such as named-entity recognition (NER).
The UI framework is based on the awesome work of Doccano, while the distinctive advantages of AlpacaTag are three-fold:
- Active intelligent recommendation: dynamically suggesting annotations and sampling the most informative unlabeled instances with a back-end active learned model.
- Automatic crowd consolidation: enhancing real-time inter-annotator agreement by merging inconsistent labels from multiple annotators.
- Real-time model deployment: users can deploy their models in downstream systems while new annotations are being made.
