Abstract

The invention discloses a keyword extraction method and device, electronic equipment and a medium. According to the invention, after a target text is obtained, the target text can be preprocessed based on a preset mode to obtain at least one candidate word, then a topic calculation model is utilized to determine at least one topic category corresponding to each candidate word, and extraction is performed from the at least one candidate word based on the at least one topic category to obtain at least one target keyword. According to the technical scheme, after irrelevant words of the target text are filtered, the topic calculation model and the target word embedding model are used for extracting the candidate keywords in the target text, and the target keywords interested by the user are obtained. Therefore, the problem of low accuracy caused by only depending on the occurrence frequency of the words to select the keywords in the prior art can be avoided.
