Retrieval and Integration
In the last part, we discussed how information sources can be semi-automatically enriched by semantic information. In this chapter, we show how information can be retrieved and transformed between different systems based on their semantic descriptions. We show that translations between different ontologies can be approximated using a minimal shared terminology. We further describe how this transformation can be exploited for content-based information filtering across different systems.
