Anybody knows a Java implementation of Constraint Grammar for natural language processing? I know the VISL CG3 implementation, that is in C++, and I could interface it from Java, but it would be easier if I could find a Java implementation since it will be integrated to a legacy Java code.
This will be used in a Portuguese open source grammar checker and should be compatible with LGPL license.

Have a look on JAPE: Regular Expressions over Annotations. A formalism based on CPSL (COMMON PATTERN SPECIFICATION LANGUAGE) in old TIPSTER project.
It’s not true context-dependent (as Context Grammar should be) but it’s possible to do context dependent things with it. This is free and open source. And has a lot of Java examples.
XTDL from SPROUT project also worth looking. Not sure is it free or not.
