e-Gnosis. Building multimedia data warehouses from distributed data
نویسندگان
چکیده
Multimedia data mediation is characterized by three important aspects: multimedia data integration, system architecture and global query evaluation. Multimedia mediation problem can be seen from an architectural point of view in which suitable mediation architectures, adapted to multimedia data characteristics (e.g. volume vs. communication and bandwidth costs) must be identified. Given multimedia data characteristics (distributed, homogeneity, volume, etc), the integration process requires time and resources. The contribution of our work is associated to multimedia data exploitation. We provide mechanisms for analyzing multimedia data collections coming from heterogeneous and distributed sources. Our solution proposes a mediated query service for distributed multimedia data, adapted to build multimedia data warehouses.

Building Spatio-Temporal Presentations Warehouses from Heterogeneous Multimedia Web Servers
Building warehouses from existing data sources is one of the main challenges of future information systems. Over the last three years, we defined and experienced an infrastructure called Jaguar (model, language, architecture, and prototype SMIL/JMF) to configure presentations warehouse(s) managers. Such managers provide means to play and query multimedia presentations stored in a warehouse. Thi...
متن کاملBuilding a Web-Enabled Multimedia Data Warehouse
Data warehousing has drawn attention as a useful approach to integrate heterogeneous data sources. Since most of data warehouses have been developed based on the relational database technology, however, difficulties are encountered, when we integrate multimedia data sources, which need a flexible data model and a content-based query language. In this paper, we study a framework for multimedia d...

متن کاملPredicting access to materialized methods by means of hidden Markov model
Method materialization is a promising data access optimization technique for multiple applications, including, in particular object programming languages with persistence, object databases, distributed computing systems, object-relational data warehouses, multimedia data warehouses, and spatial data warehouses. A drawback of this technique is that the value of a materialized method becomes inva...
متن کاملGNOSIS: Global Network Operations Status Information System
Monitoring the global state of a network is a continuing challenge for network operators and users. It has become still harder with increases in scale and heterogeneity. Monitoring requires status information for each node and to construct the global picture at a monitoring point. GNOSIS, the Global Network Operations Status Information System, achieves a global view by careful extraction and p...
