Research on Fuzzy Extension of Domain Ontology for Emergency Management of Civil Aviation

摘要

For the issue that civil aviation emergency domain ontology has not involved in the field of uncertain knowledge, the paper presents a method on fuzzy extension of domain ontology with fuzzy description logic to extend concepts and relations by means of frizzy concrete domains and fuzzy modifiers. Moreover, it gives the representation of fuzzy ontology and analysis of fulfillment effect on a basis of fuzzy description logic, which not only improves the expression ability of existing domain ontology for emergency management of civil aviation, but offers a methodological support to improve accuracy and scientistic of emergency-rescue plan further.
