Corpus

• English
  • Corpus 50 Training corpus in English (50 sentences), to be manually translated to the target languages, in order to be used as the input for IAN
  • Corpus500 Experimental corpus in English (500 sentences), to be manually translated to the target languages, in order to be used as the input for IAN
• UNL
  • Corpus 50 Training corpus in UNL (50 sentences), to be used as the input for EUGENE
  • Corpus500, Experimental corpus in UNL (500 sentences), to be used as the input for EUGENE

Methodology

The following activities must be accomplished during the workshop.

Corpus

1. Translate the 50 sentences of Corpus50_eng.txt into your native language. Be as close as possible to the original.
2. Save the translated text (without the English original) in a plain text (.txt) file with UTF-8 encoding and upload it to UNLWEB>UNLDEV>PROJECTS>IAN>NL FILES.
3. Upload the file Corpus50_unl.txt to UNLWEB>UNLDEV>PROJECTS>EUGENE>UNL DOCUMENTS

NL-UNL Dictionary (Analysis)

1. Extract the word list (i.e., the set of all distinct word forms) appearing in your translation of the Corpus 50
2. Create the NL-UNL dictionary for all the word forms following the English model available at English Analysis Dictionary 50. Use only the tags available at the tagset. For further information on the dictionary structure, see Dictionary Specs.
3. Save the NL-UNL dictionary in a plain text (.txt) file with UTF-8 encoding and upload it to UNLWEB>UNLDEV>PROJECTS>IAN>DICTIONARIES.

UNL-NL Dictionary (Generation)

1. Localize the UNL-NL dictionary available at English Generation Dictionary 50. The localized version must reflect the word list of your translated corpus. Use only the tags available at the tagset. For further information on the dictionary structure, see Dictionary Specs.
2. Save the UNL-NL dictionary in a plain text (.txt) file with UTF-8 encoding and upload it to UNLWEB>UNLDEV>PROJECTS>EUGENE>DICTIONARIES.

Morphology

1. Export the inflectional grammar of your language from UNLARIUM>GRAMMAR>[YOUR LOCALE]>EXPORT. If the grammar of your language is not available yet, you may:
   1. Provide it through the UNLarium (only for users approved in CLEA700); or
   2. Create the inflectional paradigms only for the inflected forms appearing in the UNL-NL dictionary. In that case, follow the model available at English Inflectional Grammar. The documentation of the English grammar is available at English Inflectional Grammar (only for reference). For further information, see Inflectional paradigms.
2. Save the inflectional grammar in a plain text (.txt) file with UTF-8 encoding and upload it to UNLWEB>UNLDEV>PROJECTS>EUGENE>RULES.

NL-UNL (Analysis) Grammar

1. Provide the NL-UNL (analysis) grammar necessary to analyze, in UNL, the natural language sentences of the translated corpus.
2. Save the NL-UNL grammar in a plain text (.txt) file with UTF-8 encoding and upload it to UNLWEB>UNLDEV>PROJECTS>IAN>RULES.
3. Test the grammar against the corpus and provide the necessary changes

UNL-NL (Generation) Grammar

1. Provide the UNL-NL (generation) grammar necessary to generate natural language sentences from the UNL corpus.
2. Save the UNL-NL grammar in a plain text (.txt) file with UTF-8 encoding and upload it to UNLWEB>UNLDEV>PROJECTS>EUGENE>RULES.
3. Test the grammar against the corpus and provide the necessary changes
