Claim 14:
15. The computer device according to claim 9, wherein the keyword extraction model comprises an encoding model and a decoding model, and the one or more processors are configured to perform the following operations:
performing word segmentation on a training text of a training information entity, to obtain a plurality of candidate words;
performing character segmentation on a training title of the training information entity corresponding to semantics of the training text, to obtain a plurality of characters;
sequentially inputting the plurality of candidate words to the encoding model, to obtain a text feature representation of each candidate word;
adjusting the text feature representation of each candidate word according to an attention weight of the candidate word;
obtaining a text feature representation of the training text according to the adjusted text feature representation of the plurality of candidate words;
inputting the text feature representation of the training text and the plurality of characters obtained by character segmentation to the decoding model, to obtain a plurality of target characters; and
comparing the plurality of characters obtained by character segmentation and the plurality of target characters, and respectively adjusting an attention weight corresponding to the text feature representation of the candidate word according to a comparison result.
