WebAnnostøttede

WebAnnostøttede is a Danish web‑based platform designed to facilitate the annotation and annotation of text data for natural language processing tasks. The service was launched by a consortium of researchers and software developers at the Technical University of Denmark in 2018. Its primary aim is to provide an intuitive interface for linguists, data scientists and machine learning engineers to collaboratively annotate corpora in languages such as Danish, Norwegian and English.

Key features of WebAnnostøttede include a drag‑and‑drop annotation tool that supports multiple layers of markup (token, part‑of‑speech, named entity, and syntactic relations), real‑time collaboration with version control, and export options for common formats such as CoNLL, XML and JSON. The platform is built on a microservices architecture with a RESTful API, allowing it to be integrated into existing NLP pipelines. Security is addressed through end‑to‑end encryption and role‑based access control, ensuring that sensitive data remains confidential.

Since its release, WebAnnostøttede has been employed in several academic projects, notably a Danish sentiment‑analysis corpus that achieved a state‑of‑the‑art F‑score of 0.83 on the test set. The system also hosts an open‑source community of contributors who develop plug‑ins and collaborate on shared labeling guidelines. As of 2024, the platform serves over a thousand active users across Europe and Asia, and continues to receive updates that expand its linguistic coverage and enhance its GUI.

WebAnnostøttede represents a modern approach to collaborative annotation, blending ease of use with robust technical foundations to support growing demands in NLP research and industry.
