Issues
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: 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 ofpolitiija#stašuvdna<N><Sg><Ill>
like the lookup2cg script gives). CG seesNom
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 turnsduohta<A><Sg><Nom><Cmp>+dilli<N><Sg><Acc>
intoduohta<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 seestašuvdna<N><Sg><Ill>
(later we may have CG features to refer to the other sub-readings)
- The ideal solution, but currently impossible: rename the non-head tags in BEFORE-/AFTER-SECTIONS. I tried
- 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 | ??? | ??? | should be OK, not 100% sure | ??? |
These bugs in the sme-nob analyser in GTSVN need to be fixed:
- http://giellatekno.uit.no/bugzilla/show_bug.cgi?id=873 (but there is a work-around for this in langs.cfg.in, using LEX_EXCLUDES)
- http://giellatekno.uit.no/bugzilla/show_bug.cgi?id=857#c3
- http://giellatekno.uit.no/bugzilla/show_bug.cgi?id=875
- http://giellatekno.uit.no/bugzilla/show_bug.cgi?id=872
And these generation/transfer errors need to be fixed:
