The LightSide Researcher's Workbench is an open-source text-mining tool released under the GNU General Public License. To download the latest public release, visit See copyright/gpl.txt for more information.


To build from source, use ant:

ant build

This will compile the workbench and run a modest set of unit tests.

To add new feature-extraction, machine-learning, or analysis tools to the workbench, you'll want to write a plugin. See the appendix in the Researcher's Manual for more information, and the core LightSide plugins repository for examples.
