AI Technical Summary

Technical Problem

In chatbots that use large-scale language models and Japanese document knowledge bases, the search accuracy of the knowledge base may decrease, leading to insufficient accuracy in the responses.

Method used

By dividing Japanese documents into paragraph units and establishing connections based on the relationships between paragraphs, multiple blocks are generated, which are then converted into numerical vectors and registered in a knowledge base. The search department extracts blocks related to the question text and their associated blocks from the knowledge base as search results.

Benefits of technology

This improves the search accuracy of the knowledge base, thereby enhancing the response accuracy of large-scale language models and ensuring accurate answers to user questions.

Abstract

The objective of this invention is to improve the search accuracy of a knowledge base. An information processing device includes a search unit that searches a database for blocks related to a user-inputted question. This database is generated by dividing Japanese documents into paragraph units and includes multiple blocks linked based on relationships between paragraphs. The search unit obtains search results including one block related to the question and other blocks linked to that block.
