Foma is a compiler, programming language, and C library for constructing finite-state automata and transducers for various uses. It has specific support for many natural language processing applications such as producing morphological and phonological analyzers. Foma is largely compatible with the Xerox/PARC finite-state toolkit. It also embraces Unicode fully and supports various different formats for specifying regular expressions: the Xerox/PARC format, a Perl-like format, and a mathematical format that takes advantage of the ‘Mathematical Operators’ Unicode block. .
