I UNL Olympiad

The UNL Olympiad is a series of competitions organised by the UNDL Foundation in order to foster the development of UNL-driven resources (dictionaries, grammars and corpora). The first edition of the Olympiad is devoted to the development of grammars for the corpus UC-A1, comprising 100 sentences. The competition is open to any participant, and the deadline is February 15th, 2013.

Important dates

• November 15th, 2012: Call for Participation
• February 15th, 2013: Deadline for submitting the files

Modalities

The competition is organised in two modalities:

• Best UNLization Grammar for <LANGUAGE>
• Best NLization Grammar for <LANGUAGE>

Where <LANGUAGE> is one of the languages participating in this Olympiad (see the complete list below).
Candidates may participate in one or two modalities, i.e., they may work with the UNLization grammar, with the NLization grammar, or with both.
Candidates may also participate in one or more languages, provided that they belong to the list below.

Prizes

Prizes are awarded to the best grammars of each modality (UNLization and NLization) for each language:

• 1st place: Gold Medal and USD500.00
• 2nd place: Silver Medal
• 3rd place: Bronze Medal

Additionally, the authors of the three best UNLization Grammars among all languages and the authors of the three best NLization Grammars among all languages will also be invited to participate in the next intermediate-level grammar workshop, to be held in Geneva, Switzerland, on May 2013.

Registration

Candidates must be registered at the UNLweb. Participation is open and free, and the registration to the Olympiad is done by sending the following files to r.martins@undlfoundation.org until 23:59:59 (UTC) of February 15th, 2013.

• For the participants working with the UNLization grammar (IAN):
  • UCA1_<LID>.txt, with the human translation, to the target language, of the sentences of the Corpus UC-A1;
  • <LID>_unl_dic.txt, with the natural language analysis dictionary used to UNLize the translated version of the Corpus UC-A1;
  • <LID>_unl_tgrammar.txt, with the transformation grammar used to UNLize the translated version of the Corpus UC-A1;
  • <LID>_unl_dgrammar.txt, with the disambiguation grammar used to UNLize the translated version of the Corpus UC-A1;
  • <LID>_unl_output.txt, with the output provided by IAN
• For the participants working with the NLization grammar (EUGENE)
  • UCA1_<LID>.txt, with the human translation, to the target language, of the sentences of the Corpus UC-A1;
  • unl_<LID>_dic.txt, with the natural language generation dictionary used to NLize the UNL version of Corpus UC-A1;
  • unl_<LID>_tgrammar.txt, with the transformation grammar used to NLize the UNL version of the Corpus UC-A1;
  • unl_<LID>_dgrammar.txt, with the disambiguation grammar used to NLize the UNL version of the Corpus UC-A1;
  • unl_<LID>_output.txt, with the output provided by EUGENE

Where <LID> must be replaced by the three-character language according to ISO 639-3..
All files must be provided in UTF-8.

Requisites

The competition is free and open to any participant, but it is limited to the set of languages described below.
The files must comply with the following requisites:

• The corpus must comply with the translation standards of the target language and should not be artificially translated in order to provoke better results.
• The input corpus used in UNLization will be used as the reference corpus used to evaluate the NLization output.
• The dictionary files must comply with the Dictionary Specs and may only bring features present in the Tagset. They should not contain temporary words.
• The grammar files must comply with the Grammar Specs and must be as generic possible. They should not target the specific sentences of the corpus, but the general structures presented there.
• The F-measure of the grammars must be equal or greater than 0.8.
• The files must be original. Grammars whose similarity proves to go beyond any reasonable doubt will be discarded, unless provided by the same author (for different languages).

Evaluation

Grammars will be evaluated and ranked according to the following criteria:

• Best F-measure
• Scalability (i.e., extendibility, or the capacity of being reused to other corpora), in case of grammars with the same F-Measure
• Date of submission, in case of grammars with the same F-Measure and equally scalable
