Seal is a Python library of code for computational linguistics. Among other things, it contains:
- Seal.bot, an end-to-end traditional language-understanding system, including a resolution theorem prover as back end,
- CLD, a desktop/web application for language documentation, description, and learning that also provides a platform for CL research,
- GLab, a browser-based "notebook" system for formal languages and grammar-writing that I use for teaching,
- an implementation of an oracle-driven dependency parser.
CAUTION: this is research code and very much under active development; use at your own risk. Bugs and design flaws remain. There are some incompatible changes between one version of the software and the next; code written that uses one version may need updating to work with the next version.

Cass is a partial parser that used to be available from this page. Unfortunately, it no longer compiles under current versions of gcc, and fixing the problem would require a fairly substantial rewrite. If you want the old tarfile, it is here.
