Method, device and equipment for establishing term mapping model and realizing standard word mapping

The embodiment of the invention discloses a method, device and equipment for establishing a term mapping model and realizing standard word mapping, and the method for establishing the term mapping model comprises the steps: firstly carrying out entity recognition of a standard word and a non-standard word, obtaining a corresponding segmented word, and carrying out text feature extraction of the corresponding segmented word; splicing the text features of the segmented words corresponding to the standard words and the non-standard words in the first text combination of the standard words and thenon-standard words with the corresponding relationship to obtain the overall text features of the standard words and the non-standard words, and then splicing the the standard words and the non-standard words to generate positive sample training data; splicing the text features of the segmented words corresponding to the standard words and the non-standard words in the second text combination ofthe standard words and the
