Text similarity calculation device, text similarity calculation method, and program

摘要

A method for calculating a similarity between texts with high accuracy. An image similarity calculation unit 120 converts first image information corresponding to a first text converted from a first text and second image information corresponding to a second text converted from a second text. An image similarity that is a similarity is calculated, and the text vector similarity calculation unit 140 is a text vector similarity that is a similarity between a first text vector that represents the first text and a second text vector that represents the second text. The text similarity calculation unit 150 calculates the similarity between the first text and the second text based on the image similarity and the text vector similarity. [Selection] Figure 1
