The goal of the project

The goal is to offer the Oahpa programs for students of Estonian as a foreign language.

Estonian and Oahpa

Oahpa

Oahpa has 6 programs, they can be divided in three groups

  1. Learn words
    1. Leksa: basic words and place names
    2. Numra: numerals, time and date
  2. Learn inflection
    1. Morfa-S: Inflect words
    2. Morfa-C: Inflect words in sentential context
  3. Learning to write sentences
    1. Vasta: Answering to questions
    2. Sahka: Chatting with the computer

The programs are best developed for North Saami Oahpa.

In order to get working programs for learning inflection one needs a morphological transducer. Some previous work has been done by Jaak Pruulmann-Vengerfeldt and Heli Uibo. The source code can be found here: https://github.com/jjpp/plamk

In order to get the programs for sentence writing exercises one needs a morphological disambiguator and a shallow syntactic parser. These are under development for the Estonian language and need to be improved and adapted for grammatical error checking purposes.

In this project, our minimal goal is to implement Leksa, Numra, Morfa-S and Morfa-C for Estonian. The maximal goal is to implement Vasta and Sahka as well.
