MyEachtraX: Lifelog Question Answering on Mobile

Your whole life in your pocket. That is the premise of lifelogging, a technology that captures and stores every moment of your life in digital form. Built on top of MyEachtra and the lifelog question-answering pipeline, MyEachtraX is a mobile-based application that addresses the overlook of mobile platforms in the area. Furthermore, leveraging the latest advancements in natural language processing, such as Large Language Models (LLMs) and Multimodal Large Language Models (MLLMs), the system enhances the query-parsing, post-processing, and question-answering processes in lifelog retrieval. Official lifelog questions from the previous Lifelog Search Challenges were used to evaluate the system, which achieved an accuracy of 72.2%. We identify the retrieval component as the main bottleneck of the pipeline and propose future works to improve the system.
