lifeXplore升级版实现时间+概念双重检索，快速定位生活日志记忆。
lifeXplore at the Lifelog Search Challenge 2021
- 结合时间浏览与可组合概念过滤的交互式检索
- 支持时间查询和更丰富的日志摘要功能
- 适合需要高效搜索个人生活数据的研究者
自2018年首届举办以来，生活日志搜索挑战赛（Lifelog Search Challenge, LSC）作为国际多媒体检索会议（ICMR）的同期活动，持续吸引关注。该年度现场竞赛要求参赛者在限定时间内，使用自研工具从大规模生活日志数据中检索指定记忆。作为长期参与者，我们展示了升级版lifeXplore系统：融合时间轴日志摘要浏览与可交互组合的概念过滤机制。相比以往版本，新系统引入时间查询功能、增强的日志摘要特性以及用户体验优化。
原文摘要 · Abstract (English)
Since its first iteration in 2018, the Lifelog Search Challenge (LSC) continues to rise in popularity as an interactive lifelog data retrieval competition, co-located at the ACM International Conference on Multimedia Retrieval (ICMR). The goal of this annual live event is to search a large corpus of lifelogging data for specifically announced memories using a purposefully developed tool within a limited amount of time. As long-standing participants, we present our improved lifeXplore - a retrieval system combining chronologic day summary browsing with interactive combinable concept filtering. Compared to previous versions, the tool is improved by incorporating temporal queries, advanced day summary features as well as usability improvements.
