brat rapid annotation tool

Submitted by Joel Kalvesmaki on

This online tool can be used for a wide variety of annotation tasks, including visualization and collaboration.

brat is designed in particular for structured annotation, where the notes are not freeform text but have a fixed form that can be automatically processed and "interpreted" by a computer. brat also supports the annotation of n-ary associations that can link together any number of other annotations participating in specific roles. brat also implements a number of features relying on natural language processing techniques to support human annotation efforts.
