lifeXplore at the Lifelog Search Challenge 2022

Abstract

Lifelogging creates substantial data archives that are challenging to manage and search. The annual Lifelog Search Challenge (LSC) aims at improving this situation by encouraging international teams to create interactive retrieval systems for searching large lifelog databases. The LSC challenge is held as a live event co-located at the ACM International Conference on Multimedia Retrieval (ICMR), where participating teams compete against each other by solving time-based retrieval tasks. In this paper, we present an improved version of lifeXplore -our system already participating since LSC2018. For LSC2022, we focus on improving the result presentation as well as the system's interface. CCS CONCEPTS• Information systems → Multimedia and multimodal retrieval; Search interfaces; • Human-centered computing → Interactive systems and tools.

Introduction to the Fifth Annual Lifelog Search Challenge, LSC'22

“…A revised lifeXplore system [10] featured improvements to the search result ordering, semantic geo-location data enrichment, as well as a number of improvements to the system's interface. Life-Seeker 4.0 [12] was redesigned to support use by a novice searcher.…”
