Visualising the past: annotating a life with linked open data.

ABSTRACTThis paper introduces a novel lifelogging system. The novelty of our system is that it uses open linked data to reduce the burden on the user to an absolute minimum by combining the user's private logs with data obtained automatically from the web. This in turn is annotated with data generated by the latest version of the author's portable 'life annotation' software to generate a detailed, interactive, user-friendly visual representation of the user's life experiences with little or no manual work required. This paper covers several key parts of the system that make it work. Specifically, the analysis of linked data, entity comparison with known objects and events from the user's own logs in order to determine relevance, and careful annotation of the user's data ensuring that the data's provenance is stored alongside the annotations generated.
