Researchers upgraded their previous Mysceal system to release Mysceal 2.0, which achieved certain success in LSC'21. Experiments showed that novice users significantly improved in log retrieval, and the shortcomings of the original version were addressed and improved upon.
Building an interactive retrieval system for lifelogging contains many challenges due to massive multi-modal personal data besides the requirement of accuracy and rapid response for such a tool. The Lifelog Search Challenge (LSC) is the international lifelog retrieval competition that inspires researchers to develop their systems to cope with the challenges and evaluates the effectiveness of their solutions. In this paper, we upgrade our previous Mysceal and present Mysceal 2.0 system for the LSC'21 with the improved features inspired by the novice users experiments. The experiments show that a novice user achieved more than half of the expert score on average. To mitigate the gap of them, some potential enhancements were identified and integrated to the enhanced version.
