Allasia W., Chiariglione F., Gallo F., Falchi F. An Innovative approach for Indexing and Searching Digital Rights. In: Third International Conference on Automated Production of Cross Media Content for Multi-Channel Distribution. AXMEDIS'07 (Barcelona, Spain, 28-30 November 2007). Proceedings, pp. 147 - 154. J. Delgado, K. Ng, P. Nesi, P. Bellini (eds.). IEEE Computer Society, 2007.
The objective of this paper is to demonstrate the reuse of digital content, as video documents or PowerPoint presentations, by exploiting existing technologies for automatic extraction of metadata (OCR, speech recognition, cut detection, MPEG-7 visual descriptors, etc.). The multimedia documents and the extracted metadata are then indexed and managed by the Multimedia Content Management System (MCMS) MILOS, specifically developed to support design and effective implementation of digital library applications. As a result, the indexed digital material can be retrieved by means of content based retrieval on the text extracted and on the MPEG-7 visual descriptors (via similarity search), assisting the user of the e-Learning Library (student or teacher) to retrieve the items not only on the basic bibliographic metadata (title, author, etc.).
