The intrinsic complexity and diversity of data in Multimedia Digital Libraries (MDLs) require devising techniques and solutions that are inherently different from those usually adopted in traditional Information Retrieval and Database systems. Moreover, the size and the dynamicity of MDLs force researchers to strive for efficiency, so as to guarantee real time results to the users. Finally, semantics should be also brought into context, in order to facilitate users' experience in querying,

With respect to the commonly used holistic approach, where the multimedia datum is considered as an atomic entity, our reductionist strategy considers the multimedia information as a complex combination of component subparts, and eases the fulfillment of the three above properties of efficiency, effectiveness, and semantic richness. Indeed, by decomposing multimedia information into simpler and smaller component objects, we are able to index such components without giving up the ability of querying the original information as a whole.
