Tasks 2017

The overall usage scenario for this lab edition is centered on festival participants:

  1. an insider participant who receives a microblog about the cultural event in which he will participate in will need context to understand it (microblogs often contain implicit information). The participant will also need this background information before clicking on the link.
  2. if a participant in a specific location wants to know what is going on in surrounding events relatively to artists, music or shows that he would like to see. Starting from a list of bookmarks in the wikipedia app, the participant will seek for a short list of microblogs summarizing the current trends about related cultural events. She/he is more interested in microblogs from insiders than outsiders or officials.

Three independent sub-tasks have been identified: content analysis, global search and time-line summarization.
