Summary

The OntoNL Framework provides an architecture andre-usable components for automating as much as possiblethe building of natural language interfaces to informationsystems. In addition to the syntactic analysis components,OntoNL has semantic analysis components which exploitdomain ontologies to provide better disambiguation of theuser input. We present in this paper the algorithms usedfor semantic processing of the natural language queries, aswell as an ontology-driven semantic relatedness measuredeveloped for this purpose. We also present extensive evaluationresults with different ontologies using human subjects.
