Abstract

The invention discloses a corpus keyword automatic extraction algorithm based on data mining. The corpus keyword automatic extraction algorithm comprises the following steps of obtaining a to-be-processed text; performing word segmentation processing on the obtained text; performing part-of-speech tagging and meaning tagging on words in the word segmentation set; performing word removal processingon the word segmentation set; counting co-occurrence information of the word frequency and the word pair; setting a word frequency threshold, and judging whether the word frequency of the words in the vocabulary set is greater than the word frequency threshold or not; generating a candidate keyword set; obtaining position information of each candidate keyword in the text; calculating a weight value of each candidate keyword in the text; setting a weight value threshold value, and judging whether a calculation result of each candidate keyword is greater than the weight value threshold value ornot; generating a set of keywords. According to the method, a corpus keyword extraction algorithm is optimized, the operation is simple and convenient, the keywords can be automatically extracted from the corpus, time and labor are saved, and the keyword extraction accuracy is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of corpus keyword extraction, in particular to an algorithm for automatically extracting corpus keywords based on data mining. Background technique [0002] The existing corpus keyword extraction algorithm is relatively complex, it is difficult to quickly extract the required data from it, and the keyword cannot be automatically extracted from the corpus. The extraction process takes a long time, the extraction efficiency is low, and the accuracy of keyword extraction needs to be improved. . Contents of the invention [0003] (1) Purpose of the invention [0004] In order to solve the technical problems existing in the background technology, the present invention proposes a corpus keyword automatic extraction algorithm based on data mining, optimizes the corpus keyword extraction algorithm, is easy to operate, and can automatically extract keywords from the corpus, saving time and effort, Significantly i...
