Photo Annotations: Preservation of Contents and Contexts

Photo is taken as memory of life and lives are the units of history. The value of photo fades away when the content becomes unrecognizable and context is lost over time. In this digital era, it has become easy to build contextual information for each photo with the process of annotating metadata. This paper proposes some aspects and techniques for semi-automatic photo annotation addressing several missing considerations to build a complete context that can survives over time. We also described the necessary metadata that unlocks hundreds of contextual information and proposes a model for photo labeling. The semantic organization and retrieval of photo collection is powered by hierarchical structure of Light-weight Ontology.
