This paper describes how we applied the PROTÉGÉ-II architecture to build a knowledgebased system that configures elevators. The elevator-configuration task was solved originally with a system that employed the propose-and-revise problem-solving method (VT; Marcus, Stout & McDermott, 1988). A variant of this task, here named the Sisyphus-2 problem, is used by the knowledge-acquisition community ...

The presentation concerns a draft implementation with Protégé OWL Plugin for SWRL, based on the RDF concrete syntax of the SWRL proposal. A first prototype of a SWRL Tab Widget has been achieved. It is a bridge between Protégé OWL, Racer, and Jess, intended to help reasoning with SWRL rules combined with OWL ontologies. A small example is given including an OWL ontology representing the family ...

Our goal was to evaluate the import/export capabilities of Protégé between various ontology file formats. As a starting point, we chose the Travel ontology used for the Protégé experiment from the previous EON workshop. We exported this into UML, from where we could import most of the ontology into the mainstream software development tool Poseidon. Furthermore, we exported the ontology into OWL...

We introduce an online knowledge base for semantic representation and annotation of a world heritage site in danger. For this purpose we designed ontology inside the protégé tool with multiple metadata-based schemas to represent a knowledge base for heritage buildings and to annotate heterogeneous data sources. The ontology schema also references multiple bibliographies so it can gather the com...

today. We need a Semantic Web to express information in a precise, machine-interpretable form, so software agents processing the same set of data share an understanding of what the terms describing the data mean.1 Consequently, we’ve recently seen an explosion in the number of Semantic Web languages developed. Because researchers and developers haven’t yet reached a consensus on which language ...

This paper presents an ontology reviser plug-in for Protégé. The plug-in implements several belief base contraction and revision operations for expressive Description Logics. The operations can be selected by choosing the desired properties of the outcome from a menu.

Ontology-based data access (OBDA) is a recent approach for accessing data where an ontology is connected to autonomous, and generally pre-existing, data repositories through mappings, so as to provide a high-level, conceptual view over such data. Mastro is a Java tool for OBDA developed at Sapienza University of Rome and at the startup OBDA Systems, which is able to manage an OBDA specification...
