Abstract

The invention discloses a keyword extraction method and device, relates to the technical field of data processing. The keyword extraction method and device are used for solving the problems of relatively low intelligence and efficiency of existing keyword extraction. The main technical scheme comprises the steps of obtaining a theme influence degree vector of each word in a target text, wherein the theme influence degree vector of the word is used for representing the influence degree of the word for the theme in the target text; calculating the importance degree of each word in the target text based on a word diagram of the target text and the theme influence degree vector of the word, wherein the importance degree is used for representing a degree of correlation between the word and the target text; and selecting a word satisfying a preset importance degree from the target text to serve as a keyword of the target text. The keyword extraction method and device are mainly used for keyword extraction.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a keyword extraction method and device. Background technique [0002] Keyword extraction is to extract words or phrases that can reflect the main information of the text from a given text. It plays an important role in automatic summarization, text mining, and information retrieval, especially the key method for automatic labeling. Among them, according to whether the training corpus needs to be labeled, the keyword extraction methods can be divided into two categories: supervised keyword extraction and unsupervised keyword extraction. [0003] The unsupervised keyword extraction based on word graph is based on the distribution of words in the document to establish word graph nodes, and then calculate the influence of adjacent words based on the three aspects of word coverage influence, position influence and frequency influence. Force, which is to calculate the side len...
