Use WebAnno

🄺🄴🅈 🅆🄾🅁🄳🅂 linguistics, annotation, syntax, morphology, semantics 


WebAnno is a certified web annotation service that has been developped by the Faculty of Computer Science of Technische Universität Darmstadt for the annotation of texts. More specifically, users can create their own annotation project/s and upload the data that they wish to annotate. It is a multi-user tool supporting different roles, such as annotator, curator, and project manager. The progress and quality of annotation projects can be monitored and measuered in terms of inter-annotator agreement. Multiple annotation projects can be conducted in parallel.
