Here, ontologies - which provide formal and explicit specifications of conceptualizations - play a crucial role in the information extraction process. Several OBIE systems have been implemented previously but all of them use a single ontology although multiple ontologies have been designed for many domains. We have studied the theoretical basis for using multiple ontologies in… CONTINUE READING
