Abstract
Compost English is a tool which combines the Morphium morphological analyzer and the Morce tagger using an innovative semi-supervised training method. The resulting tagger gives the best accuracy achieved for English (on standard PTB data set) so far: 97.43 % Compost English is written in Perl and C and is available for registered users only.
However, the default package does not contain the Morce tagger source code, which you can dowload directly from the Morce website.
