Corpora: Russian POS tagger

[Hailing Jiang]

Dear list members,

Does anyone know a Russian morphological analyzer or
POS tagger that is publicly available or free for
research purpose? I searched the net and only found
this online demo of Brill's tagger trained for Russian:
(http://www.ling.gu.se/~lager/Home/brilltagger_ui.html)
There is no information on how to use it.

any related information is appreciated.

Thanks in advance,
Hailing Jiang
