The second Lifelog Search Challenge (LSC 2019) will take place at ICMR 2019 in Ottawa, Canada in June 2019. Just like in 2018, LSC 2019 will be a highly interactive and entertaining workshop modelled on the successful Video Browser Showdown annual competition at the MMM conference. LSC is a participation workshop, which means that all participants will write and present a paper, as well as taking part in the live interactive search challenge. Consequently, the workshop will have two parts, (1) oral presentations, and (2) the search challenge.
The format of the workshop will be as follows:
- A conventional first session with an introduction speaker, a panel discussion and oral presentation of research papers with a paper from each participant.
- A second session which is the interactive search challenge, which will be open for all ICMR delegates to attend. All participating groups will take part in the real-time competition, which will be configured in the manner described below.
The oral presentations (with associated papers) will describe the approaches taken to develop the interactive system for the search challenge. The workshop has an associated LSC dataset (see DATA page), which is the same dataset used for LSC2018, and based on existing NTCIR-13 test collections. This dataset consists of four weeks of rich multimodal lifelog data (wearable camera images, biometrics, user activities and locations). Associated with the dataset will be 6 testing and 18 evaluation multimodal topics representing challenging real-world information needs. We intend to use both expert and novice users for the search challenge.
The first LSC workshop (LSC2018) was hosted at ACM ICMR 2018 in Yokohama, Japan. The LSC2018 webpages are archived for historical purposes. Anyone seeking the LSC2018 or the WSDM Task Intelligence dataset, please see the LSC2018 pages. These archived pages describe a password protected dataset that was used for both the LSC2018 challenge at ICMR 2018, the WSDM-Task Intelligence challenge at the Task Intelligence workshop at WSDM 2019, and also for the. LSC2019. The Proceedings of LSC2018 are available on the ACM Digital Library.
