In this paper we present an automatic method for recognizing the interconnections between a full set of wiring diagrams in order to derive a complete, global representation of the full set of electrical connections in an aircraft. To fully understand the nature of a link between diagrams, the system must not only parse the link itself, but also determine the surrounding graphical context and discover exactly what object in the target diagram is being referenced. This global understanding creates the potential to significantly reduce the burden of electrical troubleshooting.
