Issues

High priority bad translations

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



  • 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: Insert epenthetics in compounds (nob.dix has n.*.sg.ind.cmp forms for all nouns, outputting the right epenthetic based on that)

TODO [1/2]: Multiple identical tags per reading in CG

  • DONE: 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).
    • Fix: cg-proc now ignores anything up until the last baseform, so given politiija<N><Sg><Nom><Cmp>+stašuvdna<N><Sg><Ill>, the rules will only see stašuvdna<N><Sg><Ill> (later we may have CG features to refer to the other sub-readings)
  • TODO: Derivations mess up CG. In lookup2cg, PoS tags are given stars if they appear before derivational tags. We could do this with twol, but again have no way of removing them before bidix. Also, the CG sub-reading features won't help here since we can't ignore _all_ tags up until the last derivation; say we have "lemma" V TV Der/n N Sg Ind, lookup2cg gives "lemma" V* TV Der/n N Sg Ind (leaving the TV tag intact).
    • Simple solution: lexicalise.
    • Boring solution: do the twol renaming to add stars to any PoS-before-derivation, and then move all the PoS tags into pardefs:
<pardef n="V" c="treat V* exactly like V for bidix lookup">
  <e>       <p><l><s n="V"/></l><r></r></p></e>
  <e r="LR"><p><l><s n="V*"/></l><r></r></p></e>
</pardef>
...
<e><p><l>gieldit<s n="TV"/></l><r>forby<s n="vblex"/><s n="pers"/></r></p><par n="V"/><par n="__verb"/></e>

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.

DONE: bidix pardef to handle CG changing Plc to Sur

sme-dis.rle can change arbitrary Plc-tagged proper nouns into Sur tags, so bidix needs a pardef that translates LR any Sur as if it were Plc.

(might also want to split entries where sme-lemma != nob-lemma into a Plc entry, and a Sur-one where sme==nob)

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 @.

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! ???


These generation/transfer errors need to be fixed:


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.
