Generation Challenges 2010 is an initiative that aims to provide a common forum for a number of different NLG Shared Tasks.

As part of Generation Challenges 2010, we are organising a set of tasks based on the GREC-People Corpus, a corpus of 2,000 introduction sections from Wikipedia articles in which all mentions of people entities have been annotated. There are three submission tracks:

  1. GREC-NEG: participating systems select a referring expression (RE) from a given list of REs for each mention of each person entity in a text.
  2. GREC-NER: participating systems must recognise all mentions of people in a text and identify which mentions corefer.
  3. GREC-Full: end-to-end RE regeneration task; participating systems must identify all mentions of people and then aim to generate improved REs for the mentions.

Full details are provided in two Participants Packs (GREC-NEG'10 and GREC-NER/Full'10) which participants will receive on registration.

Submitted systems and evaluation results will be presented in a special session at the INLG'10 in Dublin and accompanying reports will be published in the conference proceedings.
