Myscéal: An Experimental Interactive Lifelog Retrieval System for LSC'20

Abstract

The Lifelog Search Challenge (LSC), is an annual comparative bench-marking activity for comparing approaches to interactive retrieval from multi-modal lifelogs. Being an interactive search challenge, issues such as retrieval accuracy, search speed and usability of inter-faces are key challenges that must be addressed by every participant. In this paper, we introduce Myscéal, an interactive lifelog retrieval engine designed to support novice users to retrieve items of interest from a large multimodal lifelog. Additionally, we also introduce anew similarity measure called "aTFIDF", to match a user's free-text information need with the multimodal lifelog index.
