Limitations of current methodologies th d l i • Methontology, On-To-Knowledge are for building ontologies from scratch • They lack guidelines for: – building ontologies by reusing and reengineering g g y g g g existing knowledge aware resources – for contextualizing an existing ontology and plugging it in with existing ontologies that might plugging it in with existing ontologies that might be in continuous evolution – Building ontologies in a collaborative way Building ontologies in a collaborative way – software developers that need to include ontologies into their IT developments Introduction to the Semantic Web Tutorial: Ontological Engineering
New Ontology Development Paradigm gy p g Whose emphasis is on � the reuse and reengineering of knowledge aware resources � the collaborative and argumentative ontology development � the building of ontology networks , as opposed to custom- building new ontologies from scratch.
