Technical manual is vital source of fault diagnosis and maintenance knowledge. To deal with the mass of manual text, which influence the speed of knowledge acquisition, and then effect the diagnostic efficiency, this paper proposes a method for extracting information of Chinese technical manual text based on rule-matching. With the help of domain ontology and syntactic analysis, extracting rules could be established to extract manual text information, and reasoning algorithm based on hierarchical directed graph is built to assist the fault diagnosis. The information extraction method presented in this paper can supply knowledge to maintenance staff and help to diagnose the fault automatically.
