Abstract

The present invention provides a keyword weight calculation method based on a position of a word. The method comprises the following steps of: pre-processing a document: performing pre-processing on the provided document to obtain text information; extracting a keyword: extracting the keyword from the text information after preforming preprocessing on the document; acquiring an influence factor: acquiring a weight factor of the extracted keyword; acquiring a basic weight in one aspect; identifying words in a first sentence of an abstract and an article chapter in the other aspect; performing weighted calculation: regarding the acquired influence factor as a weight calculating factor to perform final weight calculation; and outputting a keyword weight table: outputting the final keyword weight table. According to the keyword weight calculation method based on the position of the word provided by the present invention, a weight parameter of the word can be calculated accurately, so that the keyword analysis is facilitated and the understanding and memorization of readers to the content of articles are facilitated.

Description

technical field [0001] The invention relates to the technical field of digital publications, in particular to a method for calculating keyword weights based on word positions. Background technique [0002] A keyword is a word or word that is input by a user when using a search and can summarize the content of the information that the user is looking for to the greatest extent, and is the generalization and concentration of information. The keywords mentioned in the publishing industry often refer to the core and main content of the article.
