• apertium-sme-smj.sme-smj.t1x — Transfer rule file (level 1 -- Local re-ordering, chunking)

• apertium-sme-smj.sme-smj.t3x — Transfer rule file (level 3 -- Final touches)

TODO

• Mapped tags in the CG use special characters in Apertium, for example '>' (used for delimiting tags) and '-' (causes problems with pretransfer). 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.
• Closed categories in sme analyser

Reminders

• In the transfer rule files, don't forget to escape the '+' character in tags, for example:

no: <attr-item tags="@+FMAINV"/> ,

yes: <attr-item tags="@\+FMAINV"/>
