Tests with the Knowledge Annotator have yet to be done. 3 Ontology Evolution Almost every author describes the evolution of an ontology as a very important task. An integration system — and the ontologies — must support adding and/or removing sources and must be robust to changes in the information source. However, integration systems which take this into account are rare. To our knowledge, SHOE is the only system that accomplishes this to-date. SHOE: Once the SHOE-annotated web pages are uploaded on the web, the Expose tool has the task to update the repositories with the knowledge from these pages.

G. 30 2 Ontology-Based Information Sharing restricts the value range of some attributes. Since the source ontologies only use the vocabulary of the general ontology, they remain comparable. The advantage of a hybrid approach is that new sources can easily be added without the need of modification in the mappings or in the shared vocabulary. It also supports the acquisition and evolution of ontologies. The use of a shared vocabulary makes the source ontologies comparable and avoids the disadvantages of multiple ontology approaches.

The use of a shared vocabulary makes the source ontologies comparable and avoids the disadvantages of multiple ontology approaches. The drawback of hybrid approaches however, existing ontologies cannot be reused easily, but have to be re-developed from scratch, because all source ontologies have to refer to the shared vocabulary. 1. 2 Ontologies in Information Integration 31 system-generated) integration description.
