DEVICE AND METHOD FOR VISUALIZING KEY WORDS OF FEATURES EXTRACTED BY APPLYING PRINCIPAL COMPONENT ANALYSIS TO WORD VECTORS FROM TEXT DATA

摘要

A device for visualizing a key word of a feature, and the device for visualizing a key word of a feature is based on a feature information input unit and user input information for inputting importance values for target variables of a plurality of features extracted using principal component analysis from text data. A reference importance input unit for setting a reference value associated with the importance value, a word importance extraction unit for extracting an influence on each feature for each word vector for the plurality of features, and a value extracted by the importance extraction unit for each word It may include a importance calculation unit for each word that converts the importance to a percentage, and a visualization execution unit for visualizing the importance of each word and information about the extracted features in a Venn diagram graph form.
