Abstract
A document search device that can search for a text whose concept is similar to a desired concept is provided. The document search device includes an image generation portion and an image search portion. The image generation portion generates search target images on the basis of search target texts included in a search target document. A query image is generated on the basis of a query text. The image search portion calculates the degrees of similarity between the search target images and the query image, and specifies the search target text used in the generation of the search target image with a high degree of similarity as a search target text to be presented to a user of the document search device.
Claims12
A document search device comprising:
- an input portion and an output portion,
- wherein the input portion is configured to receive a query text,
- wherein the output portion is configured to present an output text specified from a plurality of search target texts in each of a plurality of search target documents included in a search target document group, and
- wherein the output portion is configured to present one query image or at least one of a plurality of query images generated on the basis of the query text and an output image specified from one or more images generated on the basis of the output text.
A document search method comprising:
- a first step of receiving a query text;
- a second step of generating a plurality of query images on the basis of the query text;
- a third step of calculating degrees of similarity between a plurality of search target images generated on the basis of a plurality of search target texts in each of search target documents in a search target document group and each of the plurality of query images;
- a fourth step of specifying at least one of the plurality of search target images on the basis of the degrees of similarity;
- and
- a fifth step of specifying the search target text used in generation of the specified search target image.
A document search method comprising:
- a first step of receiving a query text;
- a second step of generating a plurality of query images on the basis of the query text;
- a third step of calculating first degrees of similarity between a plurality of search target images generated on the basis of a plurality of search target texts in each of search target documents in a search target document group and each of the plurality of query images;
- a fourth step of calculating second degrees of similarity between the plurality of search target texts and the query text;
- and
- a fifth step of specifying at least one of the plurality of search target images and at least one of the plurality of search target texts on the basis of the first degrees of similarity and the second degrees of similarity.
