HFST: (name of this topic page)

We offer a new Python interface generated with SWIG through which HFST library can be used more easily. Compiling HFST with Windows using MinGW tools is now also supported.

Two new command line tools are added, a tagger 'hfst-tagger' and a pattern match parser 'hfst-pmatch2fst'. The regular expression parser 'hfst-regexp2fst' supports new operators (epenthesis, term negation, containment), identity symbols and many XFST-type rules. The tool 'hfst-fst2txt' also supports new formalisms, now it is possible to write transducers to dot/graphviz and PCKIMMO format.

All back-end libraries (SFST, OpenFst and foma) are bundled with the HFST library, so that incompatible versions do not cause problems. Support for default symbols is added and handling of flag diacritics is improved. We also have a new implementation of the internal transducer format, making conversions between transducer formats more efficient.
