EXAMPLE BASE RETRIEVAL METHOD AND RETRIEVAL SYSTEM FOR DETERMINING SIMILARITY

Title:

EXAMPLE BASE RETRIEVAL METHOD AND RETRIEVAL SYSTEM FOR DETERMINING SIMILARITY

Document Type and Number:

Japanese Patent JP3735335

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide an example base retrieval method and retrieval system for automatically retrieving a document to determine the similarity useful for searching for the same or similar related technique to an example document in a short time by quantitatively calculating the degree of similarity between a document of an already constructed database and the example document and providing the same to a user.
SOLUTION: This example base retrieval method and retrieval system for it include a retrieval process including a step of inputting a conventional related technical document, a step of expressing the related technical document in word vectors by specified structure analysis of the document and a step of storing the expressed word vectors, and a retrieval process including a step of inputting an example document, a step of expressing the example document in word vectors by specified structure analysis of the document, and a step of obtaining the similarity between the word vectors to the related technical document stored in the above retrieval process and the vectors to the example document.
