Patent ID: 10963637

Abstract:
A keyword extraction method is provided. The keyword extraction method is performed by at least one processor and includes: obtaining to-be-determined words of to-be-processed text; determining preceding words respectively corresponding to the to-be-determined words, where the preceding words are words appearing in the to-be-processed text and preceding the to-be-determined words; determining word sequences of the to-be-determined words according to orders in which the to-be-determined words and the preceding words respectively corresponding to the to-be-determined words appear in the to-be-processed text; inputting the word sequences of the to-be-determined words respectively into a trained cyclic neural network model; obtaining, from the trained cyclic neural network model, a probability that each of the to-be-determined words is a key word of the to-be-processed text; and determining keywords of the to-be-processed text according to the probability that each of the to-be-determined words is a keyword of the to-be-processed text and a preset threshold.
