Description
This project aimed to enhance the quality of English to Esperanto translation. The start was a bit rough but I caught up. There still remain some parts which need to be worked on, but the overall translation has improved.
Supervised Tagger Training
The English corpora available on the SVN repo were used to train the tagger. One example of how this improved the translation:
Before
$ echo 'Darkness falls across the land.' | apertium -d . en-eo Mallumaj faloj trans la lando.
After
$ echo 'Darkness falls across the land.' | apertium -d . en-eo Mallumo falas trans la lando.
Vocabulary
Thanks to tagger training, a lot of missing multiwords were identified and subsequently added. Moreover, a number of proper names were also added. In particular,
- 922 male given names
- 933 female given names
- 2000+ surnames
- and the names of a few companies and productsm, most of which were likely to be mistranslated due to being dictionary words
Constraint Grammar
I used the English CG rules from English-Kazakh language pair as a base. It contained 124 rules, 16 of which I modified. 15 new rules were added and 1 was removed.
Structural Transfer
Structural transfer rules were added for almost all possible date formats used in English. Moreover, some rules were added for cases where correctly tagging a token would not suffice.
