Temporal Summarization Track

News events such as protests, accidents or natural disasters represent a unique information access problem where traditional approaches fail. For example, immediately after an event, the corpus may be sparsely populated with relevant content. Even when, after a few hours, relevant content becomes available, it is often inaccurate or highly redundant. At the same time, crisis events demonstrate a scenario where users urgently need information, especially if they are directly affected by the event. 

The goal of the TREC Temporal Summarization Track is to develop systems for efficiently monitoring the information associated with an event over time. Specifically, we are interested in developing systems which can broadcast short, relevant, and reliable sentencelength updates about a developing event. The track has the following four main aims:
  • To develop algorithms which detect sub-events with low latency,
  • To model information reliability in the presence of a dynamic corpus,
  • To understand and address the sensitivity of text summarization algorithms in an online, sequential setting, and
  • To understand and address the s sensitivity of information extraction algorithms in dynamic settings.
