# '''Pre-requisites''' |
|||
## <s>Frequency ordered wordlist</s> |
|||
#:http://xixona.dlsi.ua.es/~fran/wordlists/asturian.freqlist.txt |
|||
# '''Asturian morphological analyser''' |
|||
## All of the high frequency closed categories (freq. >= 50/23000) — pronouns, determiners, prepositions, etc. |
|||
## 2,000 highest frequency words from each open category (noun, verb, adjective, adverb) |
|||
##:''With ~8,000 high frequency words, we should have >85% coverage on open-domain text.'' |
|||
## Adding frequent multiwords |
|||
# '''Bilingual dictionary''' |
|||
## Translations of each Asturian word into Spanish (taking into account frequency and generality in translating ambiguous pairs) |
|||
## Translations of Asturian multiwords |
|||
# '''POS Tagger''' |
|||
## Identify useful restrictions (e.g. determiner cannot follow determiner — e.g. "the<det> a<det> cat<noun>" is invalid. |
|||
## Train a tagger in an unsupervised manner on an Asturian corpus. |
|||
;Tasks |
|||
# Checking automatically generated lemma-paradigm pairs. |
|||
# Creating a translation dictionary of Asturian--Spanish |
|||
# Identifying frequent multiwords which cannot be translated word-for-word between Asturian and Spanish |
|||
# Identifying constraint/restriction rules for ambiguous sequences of words. |
|||
On top of this, at least one or two people should become familiar with how Apertium works, for example taking a look at an existing language pair (<code>apertium-es-ca</code>, <code>apertium-es-gl</code> or <code>apertium-es-pt</code> etc.) and seeing how it works, how things in there might apply to, or be adapted for <code>apertium-es-ast</code>. |
