One language pair setup nowadays is using transducers from Giellatekno and pair-specific data in Apertium. This is a tricky set up because there is a lot of machinery around the tagset conversion.

Let's assume you're using giella-xxx, giella-yyy and apertium-xxx-yyy, what are the relevant files ?

Giellatekno side

  • giella-xxx/tools/mt/apertium
    • giella-xxx/tools/mt/apertium/tagsets
      • giella-xxx/tools/mt/apertium/tagsets/apertium.postproc.relabel: This file is used for 1:1 tag conversions. For example if you want to change <cc> to <cnjcoo>.
      • giella-xxx/tools/mt/apertium/tagsets/modify-tags.regex: This file is used for 1:1, 1:n and n:1 tag conversions. For example if you want to change <sg3> to <p3><sg>.


Apertium side

  • apertium-xxx-yyy/gt2apertium.cg3r: This file is used for converting the CG file tags to Apertium tags. You may have to convert tags in more than one place.

Testing and troubleshooting

A lot of the time it takes a lot of time and patience to get the tags as they should be. Here are some tips for checking which file you need to look in.

Apertium side

Check the trimmed analyser
$ echo , | hfst-lookup xxx-yyy.automorf.hfst 
,	,<cm>	0,000000
Check the untrimmed analyser
$ echo , | hfst-lookup .deps/xxx.automorf.hfst
,	,<cm>	0,000000

Giellatekno side

Check the relabelled analyser
$ echo , | hfst-lookup tools/mt/apertium/analyser-mt-apertium-desc.yyy.hfstol 
,	,<cm>	0,000000
Check the unrelabelled analyser
$ echo , | hfst-lookup  src/analyser-gt-desc.hfstol 
,	,+CLB	0,000000
