CALL FOR TASK PARTICIPATION
LSC'21 - The fourth Lifelog Search Challenge (LSC) is being organised as a participation workshop at the ACM ICMR’21 conference in July 2021 in Taipei, Taiwan. LSC is a highly entertaining and challenging workshop focused around a live lifelog search competition, where researchers evaluate and demonstrate their multimodal interactive lifelog search engine on a shared dataset in front of an audience. At the LSC workshop, each participating team gives a short presentation about their interactive lifelog search system which is then followed by the live interactive search competition in which teams compete to solve a number of search tasks in the shortest time possible.
We encourage anyone with an exploratory multimedia search tool that allows for retrieval, interactive browsing, exploration, or navigation in a multimedia collection to participate. The dataset consists of three months of fully anonymised and redacted multimodal lifelog data (continuous capture images, locations, activities) which will require a download of about 40 GBs. The lifelog was gathered 24x7 from one individual. An online API will be provided in advance to support development and to validate the search interfaces. The topics will be presented as textual descriptions of an information need that is met by one or more moments from the lifelog data. We anticipate utilising both novice and expert users in the competition.
At present, we intend to facilitate both physical and online participation in, what we expect to be, a hybrid event. The LSC’20 workshop was a virtual event with a twitch live-stream and it attracted over 150 attendees.
In order to participate, a team must prepare a paper that describes their interactive search engine and how it operates by 20 April 2021. All papers must be formatted according to the ACM proceedings style, should not exceed 6 pages in length and be written in the English Language. LSC’21 will use a single-blind review process for paper and system selection. Submissions should be made through the ICMR’21 EasyChair submission site (https://easychair.org/conferences/?conf=acmicmr2021) taking care to select “Workshop -- Lifelog Search Challenge” as the submission track. All accepted LSC’21 papers will be published in the ACM Digital Library in the LSC workshop series, and invited to contribute to a journal special issue on LSC’21.
