In the scope of the 7th Lifelog Search Challenge (LSC'24), we present the 4th iteration of LifeGraph, a multimodal knowledge-graph approach with data augmentations using Vision-Language Models (VLM). We extend the LifeGraph model presented in former LSC challenges by event-based clustering using temporal and spatial relations as well as information extracted from descriptions of Lifelog image captions produced by VLMs.
