9 a Semantic Data Modeling Mechanism for Multimedia Database

چکیده
Semantic data modeling of multimedia data is a fundamental problem in multimedia databases. The variety, context-dependency, and ambiguity of the semantics of multimedia data create the difficulty of applying conventional data modeling techniques, which usually deal with explicit, self-contained alphanumeric data. Many semantic data modeling techniques are either explicitly proposed for multimedia or can be used for modeling multimedia data. Specifically, we describe MediaView as a novel object-oriented view mechanism that can successfully capture the elusive nature of multimedia data.

A Probabilistic-Based Mechanism for Video Database Management Systems
As more information sources become available in multimedia systems, the development of multimedia database management systems (MDBMSs) to efficiently model and search multimedia data, especially video data, becomes very crucial for multimedia applications. In response to such a demand, a probabilistic-based mechanism called the Markov Model Mediator (MMM) to facilitate an MDBMS for video databa...
متن کاملMediaView: A Semantic View Mechanism for Multimedia Modeling
The semantics of multimedia data, which features context-dependency and media-independency, is of vital importance to multimedia applications but inadequately supported by the state-of-the-art database technology. In this paper, we address this problem by proposing MediaView as an extended object-oriented view mechanism to bridge the “semantic gap” between conventional databases and semantics-i...
متن کاملTowards a Dynamic Semantic and Complex Relationship Modeling of Multimedia Data
Multimedia data is a challenge for data management. The semantics of traditional alphanumeric data are mostly explicit, unique, and self-contained, but the semantics of multimedia data are usually dynamic, diversiform, and varying from one user’s perspective to another’s. When dealing with different applications in which multimedia data is involved, great challenges arise. We first introduce a ...
متن کاملNormal Forms for Multimedia Databases
In this chapter we present normal forms for the design of multimedia database schemes with reduced manipulation anomalies. To this aim we first discuss how to describe the semantics of multimedia attributes based upon the concept of generalized icons, already used in the modeling of multimedia languages. Then, we introduce new extended dependencies involving different types of multimedia data. ...
متن کاملViews or Points of View on Images
Images like other multimedia data need to be described as it is difficult to grasp their semantics from the raw data. With the emergence of standards like MPEG-7, multimedia data will be more and more produced together some semantic descriptors. But a description of a multimedia data is just an interpretation, a point of view on the data and different interpretations can exist for the same mult...
