- Abstract:
-
To transform the text description of the system fault evolution process (SFEP) into a space fault network (SFN) for fault analyses, we propose a method for extracting the text causality of SFEP and its transformation with the basic structure of SFN. First, several typical causal relationships of events in SFEP are given. Then, the transformation process of causality and SFN basic structure is proposed. The method focuses on the key words and causal group models; the keywords and group models are enriched and supplemented through continuous model learning. Finally, the method transforms SFEP text into an SFN structure. The method is applied to the text processing of aircraft landing gear failure. The findings show that the method can be used to analyze causality in SFEP text and obtain an ideal SFN. Perfect keywords and group models are beneficial to the intelligent processing of SFEP text to SFN using computers.
