AGTK: Annotation Graph Toolkit

Annotation Graphs are a formal framework for representing linguistic annotations of time series data. Annotation graphs abstract away from file formats, coding schemes and user interfaces, providing a logical layer for annotation systems.

What's New

[2011-01-01] All of our AGTK applications have been renamed to have the "AGTK" prefix: e.g., AGTK TableTrans, AGTK MultiTrans, AGTK InterTrans, and AGTK TreeTrans.

[2007-03-31] AGLIB JAVA 1.0 has been released

[2004-01-15] AGLIB 2.0.1 has been released

[2003-07-08] AGLIB 2.0 has been released!

A bug-fix version of AGTK TableTrans for Windows (version 1.2) has been released.
