Patent Abstract: The invention discloses a method and system for event-based signal matching based on the BERT model. The method includes: calculating the semantic matching similarity and rule matching similarity between the standard alarm signal of an event and different label vectors, fusing these to obtain a comprehensive similarity, and determining the label of the standard alarm signal; predicting the probability of various event-related labels for all actual alarm signals within the event interval using the BERT model, forming a probability matrix; matching the standard alarm signal and actual alarm signals based on the label and probability matrix; and based on the matching results, monitoring the upload values of actual alarm signals, triggering changes in the corresponding standard alarm signals, and thereby determining whether to trigger an alarm event. The invention reduces the number of labels, fully exploits human experience in signal matching, improves efficiency and accuracy, and avoids repeated use of actual signals within the same event.
