Issues

High priority bad translations

What are the high-priority linguistic issues to deal with?

Would we gain a lot by inserting modals instead of adverbs for Pot/Cond verbs? Is there a better, general, way to translate the progressive? Should we get some of Francis' automatically discovered lex.sel rules? And are there any "simple" constructions that we could handle but don't yet?

• TODO: We should add a post-generator to insert epenthetics in compounds, turning eg. "ing~b" into "ingsb"
• 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)
• TODO: After bidix additions, Francis will run apertium-lex-learner
• TODO: add forms to nob.dix (that are in bidix) from nn-nb-infreq; add lexicalised compounds using existing lemmas; mwe's and other missing stuff manually
• 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)
• TODO: Compounds mess up CG. We have to leave all the tags of the non-heads in because of bidix lookup, so we get eg. politiija<N><Sg><Nom><Cmp>+stašuvdna<N><Sg><Ill> (instead of politiija#stašuvdna<N><Sg><Ill> like the lookup2cg script gives). CG sees Nom and thus applies rules that it shouldn't, etc.
  • The ideal solution, but currently impossible: rename the non-head tags in BEFORE-/AFTER-SECTIONS. I tried BEFORE-SECTIONS SUBSTITUTE (N Sg Nom Cmp) (N* Sg* Nom* Cmp) which works for the above, but CG then also turns duohta<A><Sg><Nom><Cmp>+dilli<N><Sg><Acc> into duohta<A><@→N>+dilli<N*><Sg*><Nom*><Cmp><Sg><Gen>$, while if there are several non-heads, it'll only substitute in the first part. It seems some sort of tag order mechanism would be needed in CG for the BEFORE-SECTIONS/AFTER-SECTIONS stashing method to work.
  • It's possible to do the initial renaming in a twol rule (committed, but commented out for now), but we have no way of changing the tags back in CG (an AFTER-SECTIONS rule SUBSTITUTE N* N will unfortunately merge N* and later occurences of N).

• DONE: Cond rules get modals, handled like passive in t1x (instead of "kanskje" in t3x), Pot gets "da<adv>" for now
• 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

DONE: remove unhandled derivations

Any derivations that are not handled we remove from the analyser with a twol negation rule in dev/xfst2apertium.useless.twol, this makes the lexicon a lot easier to handle for testvoc.

DONE: +G3 tag

This is used like the +Actor tag, for sme wsd (here based on "stadieveksling").

We move it after the +N tag in dev/xfst2apertium.hashtags.twol (so it gets the same position as +Actor), this makes transfer a lot simpler.

Getting a list of lemmas which have +G3 is easy (grep all nouns from bidix, analyse their lemmas and grep for lemma+G3), use this to tag bidix.

DONE: ensure we have all necessary postchunk rules

Postchunk rules are needed for any chunk containing a determiner/pronoun/adjective/noun/verb, we can easily make sure each possible chunk name has a postchunk rule (new chunks are created in t1x with names like pre_pre_nom, but may also be merged in t2x to eg. pre_pre_nom_conj_nom)

All possible SN and SA chunks should have the needed postchunk rules now.

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 @.

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	14017	486	mostly mwe's missing	???
nouns	3776	8147	mostly compounds missing	???
proper nouns	17412	0	:-) easy to find nob pardefs automatically	???
adverbs	96	143		???
prepositions	42	0	:-)	???
adjectives	463	593		???
abbreviations	???	???	see dev/abbr.todo.dix	619
