LSC2018 - The Lifelog Search Challenge (LSC) is organised as a participation workshop at the ACM ICMR 2018 conference. LSC aims to become an annual live lifelog search competition, where international researchers evaluate and demonstrate their multimodal interactive lifelog search engine on a shared dataset in front of an audience. In this workshop, each participating team starts with a formal presentation about 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.

Anyone with an exploratory multimedia search tool that allows for retrieval, interactive browsing, exploration, or navigation in a multimedia collection can participate and 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 score of all teams in a live manner.

The dataset consists of one month of anonymised multimodal lifelog data (continuous capture images, locations, biometrics, information consumption/creation activities) which will require a download of about ten GBs. An online LSC API will be provided in advance to support development and to validate the search interfaces. Additionally, a baseline textual search engine will also be provided via API to any participant who wishes to use it. The topics will be divided into three categories; five development topics, five validation topics and fifteen LSC competition topics.

In order to participate, a team must prepare a paper that describes their interactive search engine and how it operates by 31st March. All papers must be formatted according to the ACM proceedings style and should not exceed 6 pages in length and be written in the English Language. LSC2018 will use a single-blind review process for paper and system selection. Submissions should be made through the EasyChair ICMR2018 conference submission site (https://easychair.org/my/conference.cgi?conf=icmr18). Please select ‘Workshop on Lifelog Search Challenge’ as your submission track. Authors of accepted submissions with associated lifelog retrieval systems will be included in the workshop proceedings of ACM ICMR 2018, invited to participate in the workshop and afterwards, to contribute to a journal special issue on LSC 2018.
