Dear colleagues,

We are proud to make this first public announcement of the brat rapid
annotation tool, a free, open-source, web-based tool for text
annotation visualisation and editing, available from:


brat is fully configurable and can support a wide variety of
annotation tasks, including, for example:

* entity mention ("named entity") annotation
* binary relation annotation
* dependency syntactic annotation
* structured, n-ary event annotation
* attribute/meta-knowledge annotation (e.g. negation, speculation, etc.)

The tool also provides annotation support features such as text and
annotation search with detailed constraints, keyword-in-context
concordancing, and integrated configurable checking of task-specific
semantic constraints.

brat is developed as a collaborative effort between several research
groups as an open source project (MIT license), and we warmly welcome
contributions and participation from the community, including feature

We hope this tool will prove valuable to the natural language processing
community, and will gladly answer questions and welcome any feedback.

brat will be presented in the EACL 2012 system demonstration session:
