17. The non-transitory computer readable recording medium storing the ontology processing program as claimed in claim 14 , which enables the computer to execute: a function of judging whether or not, among the input data, a part of data showing a subject shows a specific concept, and determining a converting method of the part of data showing the subject based on a result of the judgment; a function of judging whether or not, among the input data, a part of data showing a property is an already-known property, and determining a converting method of the part of data showing the property based on a result of the judgment; a function of judging whether a part of data among the input data, which shows an object, is a literal or a resource, and determining a converting method of the part of data showing the object based on a result of the judgment; and a function of writing ontology in a prescribed form by using the result obtained by converting the data showing the subject, the property, and the object with the determined converting methods.
