NTCIR-18 marked the sixth iteration of the Lifelog task, which aims to advance research on multimodal lifelog organization, search, and access. This task builds on methodologies successfully deployed in previous NTCIR conferences. In this paper, we detail the test collection, outline the specific tasks, provide an overview of submissions, and present findings from the NTCIR-18 Lifelog-6 task. We conclude with recommendations for future developments in lifelog research.
