NTT Communications (NTT Com) has released the public beta versions of its proprietary “rokadoc” and “chakoshi”.

rokadoc is a technology that can convert data, including charts and graphs, owned by companies into data that generative AI can handle with high accuracy. chakoshi is a technology that can accurately determine the safety of input and output text as a countermeasure against hallucination and ethical and legal issues.

rokadoc converts unstructured data into structured data suitable for generative AI. Document file formats include Word, PowerPoint, Excel, and PDF, and the converted text can be used in conjunction with any generative AI technology (AI agent or RAG).

RAG is a technology that uses external information to improve the accuracy of inference when generating text using a large-scale language model.

In addition, its unique layout analysis technology allows it to accurately separate text and images, and generates explanatory text (captions) from images.

Chakoshi is a guardrail technology that determines the safety of input and output text for generative AI. It was designed to create an environment where companies can safely use generative AI, and has strong discrimination capabilities for Japanese.
Chakoshi can be used to prevent the leakage of confidential information when searching for knowledge within a company, and to address ethical and legal issues with chatbots that handle customer support.
The use of generative AI has led to security incidents such as the leakage of confidential information within the company, as well as ethical issues such as questions about how to make dangerous objects, and the Ministry of Internal Affairs and Communications and the Ministry of Economy, Trade and Industry have set out requirements for the safety of AI in the “AI Business Guidelines.” Chakoshi is a technology that meets these requirements.
