Northern Sámi and Norwegian/release
This page holds information about the release schedule for apertium-sme-nob.

Issues
sme-nob-specific stuff should be in sme-nob
e.g. langs/sme/tools/mt/apertium/tagsets/apertium.nob.relabel
Periods in abbreviations missing from lemma
Forms "nr" and "nr." get the exact same analysis:
$ echo -e 'nr\nnr.'|apertium -f none -d . sme-nob-morph ^nr/nr<n><abbr><acc>/nr<n><abbr><attr>/nr<n><abbr><gen>/nr<n><abbr><nom>$ ^nr./nr<n><abbr><acc>/nr<n><abbr><attr>/nr<n><abbr><gen>/nr<n><abbr><nom>$
So when translating to Norwegian, we have no idea whether to include the dot or not.
If form "nr." had lemma "nr." this would be simple.
High priority bad translations
What are the high-priority linguistic issues to deal with?
- TODO: Bidix will be added to with stuff from GTSVN
- see dev/inc* (verbs need transitivity, nouns need gender checked, words with spaces shouldn't have), see also these files with entries are not in bidix:
- dev/bidix-pronouns.todo.dix
- dev/bidix-abbr.todo.dix
- dev/bidix-shcmp.todo.dix
- TODO: After bidix additions, Francis will run apertium-lex-learner to automatically discover lex.sel rules
- TODO: URL recognition (I tried making some with lexc, it worked by itself, but took ages to compile into the regular lexc, not sure why)
- DONE: In chunker/t1x, add tags to certain verbs (eg. using def-lists) that can be used in t3x to change/remove case-prepositions (see dev/valence.txt)
- TODO: fill out with more def-list entries
- TODO: go through dev/valence.txt and mark off which examples can be handled with noun-lists, and which with verb-lists
TODO: Derivations mess up CG
Mainly a problem with the PoS-changing derivations.
In lookup2cg, PoS tags are given stars if they appear before derivational tags, so "V Der N" becomes "V* Der N". We could do this with twol, but we have no way of removing them before bidix.
- Simple / clean solution: lexicalise.
- Boring / ugly solution: add stars with twol before any PoS-changing derivation tags, then instead of
<e><p><l>geavahit<s n="V"/><s n="TV"/></l><r>bruke<s n="vblex"/><s n="pers"/></r></p><par n="__verb"/></e>
we have
<e><p><l>geavahit</l><r>bruke<s n="vblex"/><s n="pers"/></r></p><par n="__tverb"/></e>
where __tverb adds the TV tag, and all PoS changing derivations use V* instead of V.
TODO: Testvoc
Before release, we need to get testvoc out of the way – making sure there are no #'s and @'s in the output. As yet we don't have a way to create all possible surface forms from an HFST analyser, but we can at least run as large a corpus as we can find through sme-nob and look for # and @.
Generation report
The script dev/generation-test -r corpus translates a corpus and gives a frequency sorted list of errors (words marked with #, / or
@). Current status: http://apertium.svn.sourceforge.net/viewvc/apertium/staging/apertium-sme-nob/dev/generation-report.txt
Bidix inconsistency
The script dev/sme-nob.inconsistency.sh tries to generate (with nob.dix) base forms (like infinitives or singular indefinites) of the various rhs entries in the bidix. Statistics so far:
| Part-of-Speech | entries from bidix that are OK in nob.dix | in bidix but not in nob.dix | comments | in sme analyser but not bidix |
|---|---|---|---|---|
| verbs | 2536 | 0 | :) | ??? |
| nouns | 11758 | 0 | :) | ??? |
| proper nouns | 28310 | 15159 | look for PPP mark in bidix, use dev/props-from-bidix-to-nob.sh | ??? |
| adverbs | 235 | 0 | :) only one nob pardef, simple to add | ??? |
| prepositions | 42 | 0 | :) | lots missing from bidix still |
| adjectives | 1056 | 0 | :) (not sure if all forms are covered though) | ??? |
| abbreviations | ??? | 0 | :) | 0 |
| sub-/conjunctions | 25 | 0 | :) | ??? |
| pronouns | ??? | ??? | 0 | |
| ShCmp | ??? | 0 | compound parts, removed from analyser | 0 |
| Numerals | ??? | ??? | bidix should be OK, not 100% sure, still lots missing from generator! | ??? |
Expanding the morphology
Running hfst-fst2strings sme-nob.automorf.hfst.ol creates an expansion of the morphology, might be possible to use for testvoc? TODO
There's a handy script dev/gt-expand-to-bidix.sh that takes as input one word and PoS (tab-separated) per line, e.g.
galbmit V beana N
, and uses the giellatekno web-based lemma expander to create all forms of each lemma (since hfst is still not very good for that), then runs them through bidix to check for missing bidix entries.
