Abstract:
Provided are a keyword extraction method and device, and a server, which belong to the technical field of information processing. The method comprises: extracting a candidate keyword from target text (101); with regard to each candidate keyword, acquiring a valid feature corresponding to the candidate keyword (102), wherein the valid feature is a feature for determining whether a keyword is a target keyword; and according to the valid feature corresponding to the candidate keyword and a weighting coefficient respectively corresponding to each valid feature, performing calculation to obtain a probability that the candidate keyword belongs to a keyword, and determining, according to the probability, whether the candidate keyword is taken as a keyword of the target text (103).
