Towards a Novel Approach to Multimedia Data Mixed Fragmentation

subject

description

International audience; Distributed multimedia applications have emerged at an increasing rate during the last decade in several domains (video conferencing, e-health, virtual meeting rooms, etc). This has created several new challenging problems related to the data integration and fragmentation, user-oriented and adaptive interfaces, real time and network performances, etc. In this paper, we focus on the problem of data(base) fragmentation in a multimedia context. We recall in this respect that data fragmentation consists of reducing irrelevant data accesses by grouping data frequently accessed together in dedicated segments. We mainly address the issue of query and predicate implication required in current fragmentation algorithms, and provide a formal approach to identify such implications, in order to partition multimedia data efficiently. Our approach is capable of considering multimedia-based as well as semantic comparisons, both ignored in current studies but required when multimedia data come to play.
