ABSTRACT
The Interactive Electronic Technology Manual is a core element of the equipment support, and using informal means to express automatic reasoning and consistency checking of knowledge systems that can not be carried through by process knowledge. This paper, in cognizance of the high frequency of procedure description in IETM, taking troubleshooting process as an example, puts forward a procedural representation based on labeling transition system, and realizes the XML file storage in procedure description. As a result, the machine can read and operate these data. Meanwhile, this paper designs a quantitative calculating method of process semantic proximity to provide a candidate set of semantic proximity sorting as the result of procedural knowledge retrieval. Compared with existing methods, this method uses status to express the program node information, characterizes change of state by action, and comprehensively considers human-computer interactions. The XML-based procedural representation and storage facilitate interoperability between multiple systems. The formal representation of process knowledge well characterizes the fault diagnosis process in the project of Interactive Electronic Technology Manual.
