| + | |
| − | #To provide the dictionary and grammars necessary to UNLize your translated version of the Corpus<sup>500</sup> (with [[IAN]])
| + | |
| − | #To provide the dictionary and grammars necessary to NLize, to your target language, the UNL version of the Corpus<sup>500</sup> (with [[EUGENE]])
| + | |
| − | | + | |
| − | == Methodology ==
| + | |
| − | In order to prepare the dictionaries and grammars to deal with the Corpus<sup>500</sup>, follow the steps below:
| + | |
| − | === UNLization ===
| + | |
| − | #Corpus
| + | |
| − | ##Translate (manually) the sentences of the [http://www.unlweb.net/resources/corpus500/corpus500_eng.txt Corpus<sup>500</sup>] from English into your native language. Be as close as possible to the original, and provide one single translation for each sentence. This will be your input document file, and your goal will be to provide (automatically, through [[IAN]]) the UNL graphs for each sentence
| + | |
| − | ##Save the translated text (without the English original) in a plain text (.txt) file with UTF-8 encoding and upload it to UNLWEB>UNLDEV>IAN>NL FILES.
| + | |
| − | #Dictionary
| + | |
| − | ##Localize the dictionary available at [http://www.unlweb.net/resources/corpus500/dic_ana_eng.txt dic_ana_eng.txt]. Note that "localization" is not the same as "translation". You may need other features (in English, for instance, nouns do not have gender or case) or other entries. In any case, the resulting dictionary should fit your translated version of the corpus (i.e., all the entries appearing in your translated version of the corpus should appear in the dictionary). For further information on the dictionary structure, see [[Dictionary Specs]]. For an explanation of the structure of the English dictionary, see [[English_dictionary|English Dictionary]]. In case you need additional features, use only the tags available at the [[tagset]].
| + | |
| − | ##Save the NL-UNL dictionary in a plain text (.txt) file with UTF-8 encoding and upload it to UNLWEB>UNLDEV>IAN>DICTIONARIES.
| + | |
| − | #Grammar
| + | |
| − | ##Create the NL-UNL (analysis) transformation grammar necessary to analyze, in UNL, the natural language sentences of the translated corpus. This grammar is the most difficult (and the actual goal) of the whole analysis task. In order to prepare the grammar, study the [[Grammar Specs]]. Next, take a look at the structure of the [[English_grammar|English Grammar]] for a detailed example. In many cases, it would be simpler just to localize the English grammar to your own locale rather than creating a whole grammar from the scratch. The grammar is normally developed inside IAN, because we have to test it every time. But you may also prepare a draft grammar, save it in a plain text (.txt) file with UTF-8 encoding and upload it to UNLWEB>UNLDEV>IAN>T-RULES.
| + | |
| − | ##Create the NL-UNL (analysis) disambiguation grammar in order to improve the results of the transformation and to control the process of tokenization. Again, this grammar is normally developed inside IAN (at the D-RULES tab), because we have to test it every time. Consult the [[English_grammar|English Grammar]] for a detailed example of a disambiguation grammar.
| + | |
| − | ##Test the grammar against the corpus and provide the necessary changes.
| + | |
| − | | + | |
| − | === NLization ===
| + | |
| − | #Corpus
| + | |
| − | ##Upload the file [http://www.unlweb.net/resources/corpus500/corpus500_unl.txt corpus500_unl.txt] to UNLWEB>UNLDEV>EUGENE>UNL DOCUMENT. Do not do any change to this file.
| + | |
| − | #Dictionary
| + | |
| − | ##Localize the dictionary available at [http://www.unlweb.net/resources/corpus500/dic_gen_eng.txt dic_gen_eng.txt] to your locale. Note, once again, that localization is not the same as translation. The localized version must reflect the word list of your translated corpus. In any case, use only the tags available at the [[tagset]]. For further information on the dictionary structure, see [[Dictionary Specs]].
| + | |
| − | ##Save the UNL-NL dictionary in a plain text (.txt) file with UTF-8 encoding and upload it to UNLWEB>UNLDEV>PROJECTS>EUGENE>DICTIONARIES.
| + | |
| − | #Grammar
| + | |
| − | ##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:
| + | |
| − | ###Provide it through the UNLarium (only for users approved in CLEA700); or
| + | |
| − | ###Create the inflectional paradigms only for the inflected forms appearing in the UNL-NL dictionary. In that case, follow the model available at [http://www.unlweb.net/unlarium/grammar/export_grammar.php?type=M&direction=G&lang=en English Inflectional Grammar]. The documentation of the English grammar is available at [http://www.unlweb.net/unlarium/grammar/export_grammar.php?type=M&lang=en English Inflectional Grammar (only for reference)]. For further information, see [[Inflectional paradigms]].
| + | |
| − | ##Save the inflectional grammar in a plain text (.txt) file with UTF-8 encoding and upload it to UNLWEB>UNLDEV>PROJECTS>EUGENE>RULES.
| + | |
| − | ##Provide the UNL-NL (generation) T-grammar and D-grammar necessary to generate natural language sentences from the UNL corpus. Follow the sample instructions available for the analysis grammar.

| − | Before starting the activity, and in order to fully understand what is expected to be done, it is important for you to be acquainted with the following documentation:

The UC-A1 is an experimental corpus used to prepare the initial versions of the grammar for sentence-based UNLization and NLization, using IAN and EUGENE, respectively. It comprises a list of 50 structures in UNL, and is supposed to cover very basic linguistic phenomena.
The corpus UCA1 was extracted from a simplified and translated version of "The Hare and the Tortoise", by Aesop.
