Markup is an open-source annotation tool that can be used to transform unstructured documents into structured formats for NLP and ML tasks, such as named-entity recognition. Markup learns as you annotate to predict and suggest complex annotations.
We have used Markup for research projects between Swansea University and local Healthboards. We love that Markup offers us a way to quickly annotate clinic letters. It's very easy to use and packed with features such as collaborative workspaces and AI suggested annotations. It's very easy to use and can thoroughly reccomend.
Markup is a great annotation tool – logical, easy to use, creating outputs that can be uploaded to NLP applications for validation tasks. I have used it in a number of clinical NLP projects and I’m looking forward to getting on with some annotating with this version.
