Proceedings of the 4th Annual on Lifelog Search Challenge

Abstract

It is our great pleasure to welcome you to the fourth annual Lifelog Search C-'21-held during the ACM ICMR'21 conference. Motivated by the success of the first three LSC workshops and driven by the fact that lifelog organization and retrieval continue to pose significant challenges for the research community, we are organizing the fourth workshop in the LSC series. The mission of the workshop series is to support the development and comparative evaluation of interactive lifelog retrieval systems by releasing test collections and defining research challenges to be solved by the community in an open and collaborative manner. The LSC workshops are participation workshops, where participants write and present an academic paper describing their retrieval system, and then take part in a live interactive search competition. Consequently, the workshop is highly interactive and challenging for participants. LSC'21 starts with an eagerly anticipated keynote from Prof Alan Smeaton, followed by short oral presentations of participating systems and then by the search challenge which never fails to excite. The call for papers attracted submissions from Asia and Europe and ultimately sixteen papers have been selected for inclusion in the program, with authors based in Austria, Czech Republic, Denmark, Ireland, Netherlands, Switzerland, Taiwan and Vietnam. Each of these papers is accompanied by a working interactive search engine. The organizers are delighted to see such a strong community continuously building around the Lifelog Search Challenge.
