NTCIR15-MART Task : Micro Activity Retrieval Task

Tokyo, Japan
Event Date: Dec 09, 2020 - Dec 11, 2020
Submission Deadline: Jun 30, 2020
Notification of Acceptance: Aug 20, 2020
Camera Ready Version Due : Nov 01, 2020


MART (Micro-activity Retrieval Task) is an NTCIR-15 workshop data challenge task. The NTCIR15-MART pilot task aims to motivate the development of a first generation of techniques for high-precision micro-activity detection and retrieval of micro-activities of daily living, to support identification and retrieval of activities that occur over short time-scales, such as minutes, rather than the long-duration event segmentation tasks of the past work. Participating researchers will develop and benchmark approaches to retrieve micro-activities from rich time-aligned multi-modal sensor data. The provided data will be gathered by equipping the individual to gather a detailed lifelog of activities as an individual progresses through a protocol of real-world activities (e.g. using a computer, solving a problem, eating, daydreaming, etc). The chosen sensors will capture a lifelog camera data stream, biosignal activity (EOG, HR), and computer accesses to record interaction with digital artefacts. This task will present a new challenging set of micro-activity-based topics. Groups will be ranked in decreasing order of micro-activity retrieval accuracy (via mAP). Prior to the NTCIR-15 December conference participating organisations will be expected to submit a paper outlining their approach which they will then present at the MART workshop in Tokyo, Japan this coming December 2020.

Call For Paper

There will be two sub-tasks in this pilot phase of the MART task:

  • A) Retrieval task: a (novel) retrieval task that can be undertaken in an interactive or automatic manner and
  • B) Insights task: an insights task where participants (using the dataset) can explore interesting use cases of the dataset.
