CONTEXT-GENERATING DEVICE, SYSTEM, PROGRAM, AND METHOD

摘要

PROBLEM TO BE SOLVED: To solve the problem that a system cannot acquire various kinds of contexts about an entity from contexts of other adequate entities which conform to the kinds of the contexts.

SOLUTION: A context-generating device 11 includes: a management part 25 which stores management tables which are provided to correspond to entities and each store contexts and relations which include the designation of other entities and related kinds (R category); and a generation part which inputs the identification information of the first entity and the kinds (C category) of the contexts, and traces the relation of a selected R category, beginning from the management table of the first entity, on the basis of the input C category to search the management table of the second entity, and then generates the contexts of the first entity on the basis of the contexts stored in the management table concerned.
