Information inquiry method based on semantic network

The invention discloses an information inquiry method based on a semantic network. The information inquiry method is used for searching for ontology instances matched with semantic inquiry statements in an ontology library according to specific semantic inquiry statements and ranking the inquiry results. The method includes the following steps that first, ontology instance graphs are traversed; second, according to the weight and the number of semantic relation paths between the ontology instances and all inquiry keywords, the dependency between the current ontology instance and the current keyword is comprehensively calculated; third, according to the dependency between the ontology instances and all the inquiry keywords and the weight of all the inquiry keywords, the dependency between each ontology instance and an inquiry keyboard set is comprehensively calculated; fourth, the ontology instances are ranked according to the high-to-low sequence of the dependency. With the information inquiry method, the pre
