Abstract

The invention discloses an intelligent keyword extraction method and device, computer equipment and a storage medium; the method comprises the steps: converting an initial text inputted by a user into text coding information, obtaining a statement vector matrix of each statement change, extracting a vocabulary vector from the statement vector matrix, and whitening the vocabulary vector to obtain a standard unit vector corresponding to each vocabulary vector; then calculating the similarity between the standard unit vector and the statement identification vector of the corresponding statement vector matrix, and screening the word segmentation result of the initial text according to the similarity calculation result to obtain a target vocabulary meeting the vocabulary screening rule as a keyword extraction result. The method belongs to the technical field of semantic analysis, can accurately obtain the standard unit vector corresponding to the vocabulary in the initial text, and extracts the target vocabulary from the initial text as the keyword extraction result based on the similarity between the standard unit vector and the statement identification vector of the corresponding statement vector matrix. Therefore, the accuracy of keyword extraction from the text is greatly improved.

Description

technical field [0001] The invention relates to the technical field of semantic analysis, belongs to the application scene of intelligently extracting keywords from text in a smart city, and in particular relates to a method, device, computer equipment and storage medium for intelligently extracting keywords. Background technique [0002] Keyword extraction is a very common task in traditional natural language processing. Keywords are extracted from the text, which are special and can represent the basic meaning of the text. The quality of the keywords extracted from the text is crucial for downstream tasks. Critical. The traditional technical methods are to analyze and count the frequency of words in the text, and determine the keywords in the text based on the frequency of words. However, the inventors found that some words that do not appear frequently in the text may have a significant role in reflecting the characteristics of the text. , and the existing keyword extrac...
