Documentation and TODO's for apertium-sme-nob's sme morphological analyser from Giellatekno.
Contents
Description[edit]
The sme morphological analyser is a trimmed and tag-changed version of the one in Giellatekno.
Trimming[edit]
Trimming happens using the same HFST method as in the Turkic pairs etc. Compounds are not handled correctly by this method.
Tagset changes[edit]
The tagset in apertium-sme-nob is closer to Apertium's tagset, thus a bit different from the one in Giellatekno.
- We remove Err/Orth/Usage tags (+Use/Sub, etc) –
- We remove any derivational analyses that aren't yet handled by transfer/bidix
- We reorder some tags
- We change the format of tags, so +N becomes <n>, +Der/PassL becomes <der_passl>, etc.
- We change certain tags
TODO[edit]
Misc[edit]
- add entries from bidix that are missing from the analyser
- regex for URL's (don't want telefonkatalogen.no => *telefonkatalogen.nå)
- regex for acronyms like "GsoC:as" (tokenisation dependent...)
8632: SUBSTITUTE:TV_IV (V TV) (V IV) FAUXV (0 ("lávet"));-- this should be analysed as both, and disambiguated
Typos[edit]
I've seen "odda" many places ("ođđa"), can we just add these to the analyser? (Would be cool to have charlifter/Diacritic Restoration, but until then…)
- a list of high-frequency typos where the correction has an analysis
Dashes[edit]
lexc handles dashes by adding them literally (like a lemma), doing that in with a bidix pardef would be very messy (also, doesn't it give issues with lemma-matching in CG?).
Multiwords[edit]
Add simple multiwords and fixed expressions to the analyser.
- dasa lassin => i tillegg (til det)
- dán áigge => for tiden
- mun ieš => meg selv
- bures boahtin => velkommen
- Buorre beaivi => God dag
- leat guollebivddus => å fiske
- maid ban dainna => hva i all verden
- jagis jahkái => fra år til år
- oaidnaleapmái => 'see you'
- ovdamearkka => for eksempel
- Mo manná? => Hvordan går det?
- ja nu ain => og så videre
(Some of these MWE's might be very Apertium-specific, but in that case we just keep our own file and append the entries with update-lexc.sh.)
Also, oktavuohta.N.Sg.Loc turns into an mwe preposition in nob:
- oktavuođas => i forbindelse med
it'd be a lot simpler for transfer to just analyse such a fixed expression as oktavuođas.Po in the first place.
