Adapting general linguistic knowledge to applications in order to obtain friendly and efficient NL interfaces
Marta Gatius · 1997
This work, supported by the project ITEM and the project BASURDE and the GRUPS DE RECERCA CONSOLIDATS proposes a mechanism for adapting general linguistic knowledge to applications in order to obtain automatically application-restricted NL interfaces. The knowledge involved in the process is represented in separate data structures: a conceptual ontology, a linguistic ontology, a general lexicon and a set of control rules. The general and application-dependent knowledge relevant to the communication tasks is represented in a conceptual ontology. The general linguistic information is represented in a linguistic ontology. The core of our approach consists of describing the application elements (both entities and operations) relevant to the communicative tasks in terms of the existing conceptual ontology. Lexical coverage of these elements has to be provided as well. A general basic set of control rules will then relate the application specifications to the linguistic ontology in order to obtain application-restricted NL interfaces. The system has been applied to provide NL interaction to SIREDOJ, an already existing expert system in the legal domain.
