What you need
- A sentence-aligned parallel corpus
- Fast_align (get it here)
- Two apertium language packages
- fast_align merge script (get it here)
Process
First analyse the corpus with the language packages.
$ cat /tmp/udhr.kaz | apertium-destxt | lt-proc -w ~/source/apertium/languages/apertium-kaz/kaz.automorf.bin | cg-proc -n -1 ~/source/apertium/languages/apertium-kaz/kaz.rlx.bin | apertium-retxt > /tmp/udhr.kaz.tagged $ cat /tmp/udhr.kir | apertium-destxt | lt-proc -w ~/source/apertium/languages/apertium-kir/kir.automorf.bin | cg-proc -n -1 ~/source/apertium/languages/apertium-kir/kir.rlx.bin | apertium-retxt > /tmp/udhr.kir.tagged
Then remove superfluous tags (for example for lexical alignment, case is not really interesting).
cat /tmp/udhr.kaz.tagged | sed 's/\(<\(n\|adj\|adv\)>\)\(<[^>]\+>\)\+/\1/g' | sed 's/\(<v><tv>\|<v><iv>\)\(<[^>]\+>\)\+/\1/g' | sed 's/\$/$ /g' | sed 's/ */ /g' | apertium-pretransfer > /tmp/udhr.kaz.trimmed cat /tmp/udhr.kir.tagged | sed 's/\(<\(n\|adj\|adv\)>\)\(<[^>]\+>\)\+/\1/g' | sed 's/\(<v><tv>\|<v><iv>\)\(<[^>]\+>\)\+/\1/g' | sed 's/\$/$ /g' | sed 's/ */ /g' | apertium-pretransfer > /tmp/udhr.kir.trimmed
Create the input file for fast_align:
$ paste /tmp/udhr.kaz.trimmed /tmp/udhr.kir.trimmed | sed 's/ *\t */ ||| /g' > /tmp/udhr.kaz-kir.input
Run fast_align:
$ ./fast_align -d -v -o -i /tmp/udhr.kaz-kir.input > /tmp/udhr.kaz-kir.align $ ./fast_align -d -v -o -r -i /tmp/udhr.kaz-kir.input > /tmp/udhr.kir-kaz.align
Create the wordlist:
$ python3 ~/scripts/ordlist-fra-fastalign.py /tmp/udhr.kaz-kir.input /tmp/udhr.kaz-kir.align /tmp/udhr.kir-kaz.align
