The invention discloses a visual document atlas construction method, which comprises the following steps of S1, sequentially extracting keywords from an input text, carrying out sentence segmentationon the input text, carrying out word segmentation on each single sentence generated by sentence segmentation, and sequentially carrying out part-of-speech tagging, named entity identification and dependency syntax analysis on each word formed by word segmentation; S2, formulating a relationship extraction rule, and extracting triple data from each simple sentence obtained in S1 based on the relationship extraction rule, wherein the triple data is composed of two entity words and a relation word; S3, importing the triple data obtained in the S2 into a graph database to form a document graph; and S4, performing graph mining operation on the data in the graph database, and realizing document graph visualization based on the mining operation. According to the visual document atlas constructionmethod, the key information of the text can be extracted, and the document is mapped into the visual graph based on semantic association, so that a user is helped to efficiently master the semantic information of the article.
