This year represents the fourth iteration of the TREC Microblog track, which has been running since 2011. The track continued using the evaluation as a service model 8, 7, in which participants had access to the document collection only through an API. In addition to the temporally-anchored ad hoc retrieval task, which has been running since the inception of the track, we introduced a new task called tweet timeline generation TTG, where the goal is to produce concise summaries about a particular topic for human consumption. Although this overview covers both tasks, more emphasis is placed on the tweet timeline generation task, which necessitated the development of a new evaluation methodology. We refer the reader to previous track overview papers 8, 12, 9 for details on the setup of the ad hoc task.
