TODO

• Mapped tags in the CG use special characters in Apertium, for example '>' (used for delimiting tags) and '-'. These should be replaced somehow.

Example:

^Wikipedia<N><Prop><Sg><Nom><@SUBJ>>$ or ^prošeakta<N><Sg><Nom><@<SPRED>$

This comes from the CG tag @SUBJ>

• Re-train the HMM-based POS tagger on a Sami corpus.
