***** LSC2020 CALL FOR PAPERS *****
The third Lifelog Search Challenge (LSC2020) is organised as a participation workshop at the ACM ICMR 2020 conference in June 2020 in Dublin, Ireland. LSC is an annual live lifelog search competition, where international researchers evaluate and demonstrate their multimodal interactive lifelog search engines on a shared dataset in front of an audience. At LSC2019, a total of nine participating teams took place in the live search challenge. In this workshop, each participating team starts with a formal presentation of their interactive lifelog search system,  which is then followed by the live interactive search competition in which teams compete to solve fifteen known-item search tasks in the shortest time possible. The search tasks are presented by a gradually extended text description, which may have vague or even misleading clues to simulate fuzzy recollection.

Anyone with an exploratory multimedia search tool that allows for retrieval, interactive browsing, exploration, or navigation in a multimedia collection can participate; there is no restriction in terms of the allowed features. At the competition, the organisers will provide an API to evaluate found items for correctness. Therefore, all participants will be connected to the server via a dedicated WiFi network and need to submit found items to the server via a simple HTTP-like protocol. The server is connected to a projector and presents the current scores of all teams in a live manner.

The dataset will consist of six months of anonymised multimodal lifelog data (continuous capture images, locations, activities and the output of state-of-the-art concept detectors), which will require a download of about 50 GBs. An online API will be provided in advance to support development and to validate the search interfaces.

In order to participate, a team must prepare a paper that describes their interactive search engine (and any additional data annotations) by 12th March 2020. All papers must be formatted according to the ACM proceedings style and should not exceed 6 pages in length (including references) and be written in the English language. LSC2020 will use a single-blind review process for paper and system selection. Submissions should be made through the EasyChair LSC2020 submission site ( <>). Accepted submissions will be included in the workshop proceedings of ACM ICMR 2020. Authors are expected  to participate in the workshop with their associated lifelog retrieval systems, and can contribute afterwards to a journal submission on the LSC 2020 challenge. The winner of the competition will be asked to lead this collaborative effort as first author.
