What does the Query Optimizer do?
The Query Optimizer allows applications to query large knowledge bases, whose entire set cannot be loaded into the working memory, by querying the ontology source for appropriate pieces, as they are needed. In addition, the task of the Query Optimizer is to not only optimize the retrieval of information from ontology sources, but also coordinate queries that span multiple sources. This component is still under construction and will be added to future editions of IBM Ontology Management System.
