Using application-specific ontologies to improve performance in a bottom-up parser
Marta Gatius, Meritxell Gonzàlez · 2006
This paper describes how the application specific knowledge represented in ontologies is used to improve the processing of user interventions in a multilingual dialogue system for multiple applications. The user interventions are processed by a left-corner parser performing syntactic and semantic analysis in parallel. The parser uses application-restricted grammars and lexicons obtained from ontologies representing the application specific knowledge. It also uses the knowledge of the dialogue context to select the grammar rules related to the dialogue focus.
