Ontology-based Controlled Natural Language Editor Using CFG with Lexical Dependency

Ontology-based Controlled Natural Language Editor Using CFG with Lexical Dependency

This video was recorded at 6th International Semantic Web Conference (ISWC), Busan 2007 . In recent years, CNL (Controlled Natural Language) has received much attention with regard to ontology-based knowledge acquisition systems. CNLs, as subsets of natural languages, can be useful for both humans and computers by eliminating ambiguity of natural languages. Our previous work, OntoPath [10], proposed to edit natural language-like narratives that are structured in RDF (Resource Description Framework) triples, using a domain-specific ontology as their language constituents. However, our previous work and other systems employing CFG for grammar definition have difficulties in enlarging the expression capacity. A newly developed editor, which we propose in this paper, permits grammar definitions... Show More
