Markup is an online 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 in order to predict and suggest complex annotations. Markup also provides integrated access to existing and custom ontologies, enabling the prediction and suggestion of ontology mappings based on the text you're annotating.
Annotations may be offset when annotating across newlines in CRLF (Windows) text documents. The offset is purely visual; the exported indicies will be correct.
When using the website version of Markup, certain features may freeze while annotations are being predicted.
