More Information
Summary:The invention provides an entity relationship extraction method for an airborne software fault report, which comprises the following steps: S1, data cleaning: converting an obtained original airborne software fault report into a standardized data format; s2, data preprocessing comprises removal of useless symbols, word segmentation and removal of stop words; s3, data annotation: carrying out data annotation on the airborne software fault report text after data preprocessing; s4, correlation analysis: establishing a concatenation table based on frequency distribution according to the entity pair set, constructing a preliminary domain relation set R, and performing adjacent relation merging; s5, relation labeling: labeling the entity pair to obtain an entity pair with relation labeling; s6, constructing a sequence prediction model; s7, constructing a relation classification model; s8, predicting a new entity relationship; in the data processing stage, the text word segmentation processing method oriented to the
