Perhaps [Earley's algorithm http://en.wikipedia.org/wiki/Earley's_algorithm] to parse context-free grammars (which has a left-to-right longest-match philosophy as Apertium) could be used to perform more complex syntactical transformations; this could be useful for distant language pairs containing embedded structures.

Open questions:

  • Currently, Apertium uses text streams to communicate. I assume this would not be possible here.
  • When would one call the bilingual dictionary? Apertium Level 2 calls it in the first stage.
  • We should check whether this has been done before.
