description The invention relates to a data mining method based on keywords, which solves the technical problems of low efficiency and high repeatability, and comprises the following steps of counting and defining the waveform frequency and amplitude of characters, defining at least one keyword, and generating a character string waveform for representing the keyword according to the character frequency; generating a waveform set to be mined from the source data; establishing a waveform matching detection model, marking waveforms in the waveform set according to a sequence, and inputting the waveforms intothe waveform matching detection model in parallel for parallel signal detection; within the time period length of the character string waveform corresponding to the keyword, taking the waveform segment corresponding to the amplitude value detected by the signal is 0 as an optimal result of matching of the current branch and the current keyword; and selecting an optimal matching result with all keywords, marking the same
