Mobile multimedia object management for efficient content search and exchange

In Mobile Multimedia Object (M³O) retrieval, high precision is required, as there is limited scope for browsing or relevance feedback due to limitations in both time and display size. In M³O, three kinds of data will need to be managed: raw content data; metadata for assisting non-content based searches; structured content description data to facilitate fast content based searches. These three kinds of data have to be processed and integrated to support efficient M³O management and retrieval. This paper examines methods, both automatic and semi-automatic, for capturing data that will support accurate M³O data retrieval. A data architecture and organisation structure of mobile multimedia data is presented.
