Applications and Good Practices of Semantic Technologies

In the following article we point out the potentials of semantic technologies by the employment within concrete applications. The areas of application cover semantic search systems, which support the discovery of documents and data base information, solutions for the semantic integration of distributed data sources up to semantic expert systems. On the basis two practical examples the applied technologies are illustrated. The first example demonstrates the employment of a ontology-based system for the search and integration of documents and data in a large German telecommunications enterprise. Different sources - e.g. a DMS system and an Intranet - are integrated by ontologies, what enables the cross-over search over the entire system. The second industrial project shows the employment of a semantic expert system to support customer service at a manufacturer of industrial robots. Apart from the applied problem solving methods the project also points out the integration of structured sources. Semantic technologies have left the research laboratories and deliver great benefit in industrial projects. This central statement of our contribution is extended by deep explanations of the applied methods and tools.
