Abstract

A candidate extraction apparatus, a candidate extraction method, and a candidate extraction program extract appropriate candidates for an input into a processing module. The processing module is associated with first metadata indicating a condition of the input data. A plurality of devices are each associated with second metadata indicating an attribute of the input data output from the device. The candidate extraction apparatus includes a first obtaining unit, a second obtaining unit, and an extraction unit. The first obtaining unit obtains the first metadata. The second obtaining unit obtains the second metadata associated with each of the plurality of devices. The extraction unit extracts the candidates greater in number than at least one input port from the plurality of devices based on the first metadata and the second metadata.
