Method and device for identifying named entities in statements

The embodiment of the invention discloses a method and device for identifying named entities in statements. The method comprises the steps of obtaining a character vector and a word vector of a targetstatement; and inputting the character vector corresponding to each character and the word vector corresponding to each word into a pre-trained recognition model, outputting a label representing a word attribute corresponding to each word by the recognition model, and outputting the word belonging to the named entity in the target statement according to the label corresponding to each word. The recognition model is weighted and combined through an attention function number vector and a word vector; wherein each word is the weight of the named entity relative to other words of the whole statement; according to the method, useful information for named entity recognition is extracted, the influence of words, not belonging to named entities, in statements on the model training process is weakened, the accuracy of rec
