Developing interactive lifelog retrieval systems is a growing research area. There are many international competitions for that encourage researchers to build effective can address the multimodal challenge of lifelogs. The Lifelog Search Challenge (LSC) was first organised in 2018 and currently only benchmarking evaluation systems. Participating should have an accurate search engine user-friendly interface help users retrieve relevant content. In this paper, we upgrade our previous MyScéal,...

The Lifelog Search Challenge (LSC) is an interactive benchmarking evaluation workshop for lifelog retrieval systems. challenge was first organised in 2018 aiming to find the system that can quickly retrieve relevant images a given semantic query. This paper provides analysis of performance all 17 systems participating 4th LSC held at 2021 Annual ACM International Conference on Multimedia Retrieval (ICMR). LSC'21 largest effort comparing different approaches seen thus far. Findings from...

Lifelogging is an activity of recording all events that happen in the daily life individual. The can contain images, audio, health index, etc which are collected through various devices such as wearable cameras, smartwatches, and other digital services. Exploiting lifelog data bring significant benefits for lifeloggers from creating personalized healthcare plans to retrieving past. In recent years, there has been a growing development interactive retrieval systems, competitors at annual...

The advent of large language models (LLMs) has energised research in Question-Answering (QA) tasks, enabling responses across varied domains like economics and mathematics. Despite their capabilities, LLMs often lack explainability due to complex parameter embeddings. Additionally, integrating multimedia data into QA systems introduces challenges processing interpreting diverse types such as text, images, audio, video. This necessitates sophisticated algorithms for accurate information...

Retrieval is a fundamental challenge within the research community of lifelog and Lifelog Search Challenge (LSC) has been an important annual benchmarking activity for interactive retrieval systems since 2018. This paper proposes MyEachtra (/mai-AK-truh/), system designed upcoming LSC'23 workshop. Improved upon MyScéal, which was top performing from LSC'20 to LSC'22, includes modifications address challenges non-owner user understanding contexts open-ended question answering. Specifically,...
