[Corpora-List] Announcing the availability of the MITRE Annotation Toolkit, version 2.0.4

[Samuel Bayer]

All -

My colleagues and I are pleased to announce the availability of version 
2.0.4 of the MITRE Annotation Toolkit.

What is it?
-----------

MAT is a suite of cooperating, loosely-coupled tools for supporting the 
human annotator in constructing models and corpora for computational 
linguistics and analysis, especially using the iterative "tag a little, 
learn a little" workflow. MAT includes MITRE's open source Java Carafe 
CRF trainer/tagger; a Web-based annotation and process control UI; a 
flexible and powerful scorer; an XML-configurable experiment harness; a 
workflow manager; and more.

MAT is platform-independent, open source, and compatible (with some 
effort) with multiple trainer/tagger engines and hand annotation tools.

You can learn about MAT 2.0, and download it, at

What's new in version 2.0?
--------------------------

The thrust of MAT 2.0 has been extending many of the MAT capabilities to 
deal with relations and other dimensions of a significantly more 
elaborate annotation model. You can find a list of changes and 
improvements in the documentation.

How stable is it?
-----------------

For many years, MAT has served as the underpinning of MITRE's 
Identification Scrubber Toolkit (MIST), an open-source package for 
deidentification of free-text medical documents. As MIST, it has been 
used by a wide range of researchers in this area. MAT itself has been 
used extensively by MITRE in its internal research and development 
projects, and by a variety of MITRE's sponsors.

Is it supported?
----------------

Unfortunately, no. MITRE doesn't (currently) have the resources to 
provide public open-source support. There is a public mailing list on 
Sourceforge, which the MITRE developers subscribe to, but we likely 
won't have the resources to answer.

On the other hand, MAT has been under development for almost seven 
years, and has seen a good deal of use, and comes with a ton of 
documentation.

Future work
-----------

MAT 3.0 is slated for public release in the early spring. It will 
feature significantly more flexible workflows for multi-step annotation 
tasks, as well as a general hand-reconciliation tool for conflicting 
annotations, including relations and events.

If you download MAT, and you like it, please let us know. Also, if you 
have ideas about other venues where we should announce the availability 
of MAT, please let us know.

Cordially,
Sam Bayer
