Natural Language Toolkit
The Natural Language Toolkit, or more commonly NLTK, is a suite of libraries and programs for symbolic and statistical natural language processing (NLP) for English written in the Python programming language. It was developed by Steven Bird and Edward Loper in the Department of Computer and Information Science at the University of Pennsylvania. NLTK includes graphical demonstrations and sample data. It is accompanied by a book that explains the underlying concepts behind the language processing tasks supported by the toolkit, plus a cookbook.

Foma (software)
Foma is a free and open source "finite-state toolkit" created and maintained by Mans Hulden. It includes a compiler, programming language, and C library for constructing finite-state automata and transducers (FST's) for various uses, most typically Natural Language Processing uses such as morphological analysis.
Foma can replace the proprietary Xerox Finite State Toolkit for compiling and running FST's written in the "lexc" and "xfst" formalisms. The speed is comparable with the Xerox tools for
