Icelandic and English

Pending tasks

• Write a TSX file to group together fine tags into coarse tags.
• Tag a corpus with IceTagger and train the apertium-tagger
• Post-edit automatically-generated bilingual dictionaries
• Try and convert some IceTagger constraint rules to work in constraint grammar
• Use IceParser to parse a corpus and extract the most frequent patterns in terms of chunks/phrases (lists of coarse POS tags) and phrase patterns (in terms of chunks/phrases).
• Merge analysed corpus (IceMorphy full-form list) with Apertium dictionary — will require matching partial information to paradigms... perhaps use extract ?
• In the Icelandic analyser (apertium-is-en.is.dix):
  • Fix verb paradigms... most are missing:
    • Participle forms (declensions) and infinitives
    • Active and middle voice distinction (see file dev/is-tags.mapping.txt for tag mapping details)
    • Verbs are missing the supine
  • Check declensions for adjectives to see if any parts can be factored out (e.g. the weak/strong inflection)
    • Move 'sta' and 'vei' tags to the end of the declension.
• Write transfer rules — start with most frequent patterns (as found from the corpus)
