The Bangor Autoglosser allows CHAT files to be glossed (POS-tagged) automatically in Welsh, Spanish and English.
The code (licensed under the GPL v3) is available on GitHub.
Note that it's not really packaged properly, because a lot of the work was done ad hoc. (To get a smaller, cleaner implementation, try the Gáidhlig autoglosser.) Hopefully this will be remedied (at least for Welsh) as part of the work on the new CorcCenCC (Corpus Cenedlaethol Cymraeg Cyfoes - National Corpus of Contemporary Welsh).
For publications about the autoglosser, see the publications page.
The databundle referred to in the ISB8 presentation is available here.
