Lsx module report

Project description

The purpose of this project is to allow Apertium language-pair developers to better translate "seperable" or "discontiguous" multiwords. We do this by re-ordering word tokens before translation occurs. For example, "take something out" becomes "take out something" so that "take out" can be translated as a single unit.

To do this, a finite-state transducer was used. The transducer accepted certain patterns of words (paradigms), such as adj-noun or det-adj-noun, that could separate the multiword. If the pattern was accepted, then the transducer would output the re-ordered words for better translation quality.

Work done

• established dictionary format
  • <j/>, <t/>, <w/> are supported within pair entries and loop as expected

• all spacing, punctuation, and superblanks were preserved

• support for the "plus thing":

echo "^абай<adj>$ ^бол<v><iv><neg><aor><p2><sg>+ма<qst>$^.<sent>$" | lsx-proc kaz-kir.autoseq.bin
^абай бол<v><iv><neg><aor><p2><sg>+ма<qst>$^.<sent>$

• (for language developers: have the language-data writer write it explicitly in the .lsx file)

Future work

• 10:53 firespeaker: pektii: if we offload multiwords from the transducers to lsx, (1) how do we do N N compounds with lsx? (2) how does translation *to* a multiword work?
• recycling dictionaries and/or paradigms? lsx-dictionaries are packaged in language pairs. the eng-spa lsx-dictionary can mostly be reaped by eng-cat. could we make use of the similarity?
• Support for language pairs: we haven't gotten much extensive beta testing. The following are language pairs that have packaged the lsx-module:
  • eng-cat
  • eng-deu (?)
