Executive Summary

Devising a uniform paradigm for the representation of multimedia data contents in distributed systems in the presence of heterogeneity, distribution, and semantic gap is a difficult task. When adding technological limitations to this mix, the problem becomes more complex. In this paper, the authors present a logic-based model for representing the semantics of complex multimedia data objects. The model employs first-order logic to describe the semantic contents of multimedia data, such as visual objects and color/texture features. The aim of this model is to provide general multimedia content representation that can be used in object-oriented information systems.
