[edit] Issues

[edit] sme-nob-specific stuff should be in sme-nob

e.g. langs/sme/tools/mt/apertium/tagsets/apertium.nob.relabel

Alternatively (ideally), there shouldn't be sme-nob-specific tag changes; all apertium pairs should have pretty similar tagsets.

[edit] 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.


[edit] High priority bad translations

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



  • 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

[edit] 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.

[edit] Testvoc

Before release, we need to get testvoc out of the way – making sure there are no #'s and @'s in the output. The analyser is trimmed, but we can still have generator errors (and CG substitute errors). We can't create all possible surface forms from a cyclic HFST analyser, but we can at least run as large a corpus as we can find through sme-nob and look for # and @, and also send through the right-hand-sides of the bidix.

There are two helper scripts:

  • dev/sme-nob.inconsistency.sh | grep '^#' should give no results. This script just sends the rhs of the bidix through the generator.
  • sed 's/^/sme\t/' smecorpus.txt | dev/analyse-all-stages.sh > analysedcorpus.txt</dev> – here <code>grep 'DGEN.*#' should give no hits. This script also outputs the input and morph and tagger stages (and nob-sentence if handed a parallel corpus)



[edit] Expanding the morphology

Running hfst-fst2strings sme-nob.automorf.hfst.ol creates an expansion of the morphology, might be possible to use for testvoc.

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.
