CONTEXT PROCESSING DEVICE, INFORMATION PROCESSING DEVICE, CONTEXT PROCESSING METHOD, AND COMPUTER PROGRAM

摘要

[Problem] To provide a technology whereby, while context information which is gathered from an induction object is scaled to other context information which has a high correlation with the induction object, said context information is not scaled to other context information which has no or a low correlation therewith. [Solution] A context processing device comprises: an ontology information storage unit (11) which stores ontology information including ontology node information and relationality information between the ontology node information; an ontology search rule information storage unit (12) which stores ontology search rule information whereby a search is permitted which reaches the relationality with respect to the ontology node information; a context acquisition unit (13); an ontology information search unit (14) which sequentially executes a search process which searches, among other ontology node information which has a relationality with the ontology node information which correlates with the context information, for that for which the search is permitted by the ontology search rule information, and adds each piece of the searched ontology node information to a scaled context list; and a scaled context list output unit (15).
