Agenda

  • Estonian FST

Estonian FST

Heiki has maybe discovered a way to decrease the number of inflection types of verbs -> simplification of the FST.

Papers/articles

MT

Typology

  • Production vs. understanding
    • fin-est and est-fin equally relevant for both types (?)
  • Lmin vs. Lmaj (or: mono- or bilingual users)
    • fin-est becoming more symmetric as time passes

This could also involve sme-X and X-sme. English-Irish as a good example of a pit to fall in (no use for system for understanding)

Key question(s):

  • What do we need a MT system for?
  • ... and does the MT system give us what we want?

Aarne Ranta: Meaning representation: TODO: Heiki to provide AR reference.

Trond:

Google Translate is a system used for understanding, but unfortunately it is better suited for production:

  1. good at idiomatic expressions, getting long strings of words correct
  2. totally unreliable for keeping track of semantic roles

RBMT out of fashion:

  1. not that suited for production of distantly or unrelated lgs
    1. especially bad for English, which has underspecified words (N = A = V)
  2. making RBMT systems requires work and tag standardisatoin
  3. All RB things out of fashion

RBMT for closely rel lgs

  1. reliable: whodonnit = ok
  2. less editing (similar syntax)
  3. but to get it good, one would need to do the

Quoting Wikipedia:

To translate between closely related languages, the technique referred to as rule-based machine translation may be used.

Ordinary MT system presentation papers

  • sme-fin is a good candidate
  • fin-est (together with fin-sme?) the best candidate?
  • or eventually est-fin (together with sme-fin)?

Neural networks

For one example, see: Google Brain

Oahpa-est

  • System in use papers

Efficiency testing

This should come at some point later this spring. Heli has some thoughts on experiment setup. Teachers should be asked about relevant grammar topics. Pupils should be tested before and after using Oahpa.

Popularity testing

Usage statistics is (hopefully!) being collected all the time.

Preparation

  1. Collect statistics
  2. Look at earlier papers
  3. Choose an approach (learning effect e.g.)

Oahpa-vro

  • System in use papers

The vro users will be asked to fill in questionnaries. So, in addition to the issues above, there is this source.

Next meeting

Friday Jan 13th, 1300 Norw time.

TODO: Follow up the article issue.
