Context-aware and semantic-based technologies have been successfully employed to improve multimedia management in mobile environments. Large sets of context-tagged images on the Web are a concrete example of this achievement. The authors present two mobile systems, MMedia2U and CAPTAIN, that take the concept of context-aware multimedia management beyond photo organization and annotation. CAPTAIN is a tool that helps generate logbooks using context-tagged images and tracking data. Crewmembers used this tool to manage multimedia content and publish it to a blog during a sea expedition. MMedia2U is a mobile photo recommender system that exploits the user's context and context-tagged images to improve photo recommendation.
