GridOne announced that it has built the business-use generative AI service 'K-water GPT' for Korea Water Resources Corporation (hereinafter referred to as the Water Resources Corporation) and officially opened it on the 21st.
This service is a search augmentation generation (RAG)-based system, and after pre-opening the private regulations and work standards functions on December 4th of last year, the entire service was officially applied to work today. Among domestic public institutions, the Korea Water Resources Corporation is the first to officially open a RAG-based work system.
In building the 'K-water GPT', GridOne's RAG solution 'GO RAG' was applied. GridOne combined its self-developed robotics automation (RPA) and image text extraction (AI-OCR) technologies with RAG to extract meaning from unstructured documents (HWP, PDF, etc.) and enable AI to provide answers based on the latest data. In addition, a high-performance lightweight large language model (LLM) was built internally to prevent information leakage and reduce the initial introduction burden.
The 'K-water GPT' service is characterized by ▲AI analyzing the user's question type and applying an optimized search method, ▲a function that allows users to search only the data they want, ▲combining the contents of multiple documents and displaying the source and preview to improve answer accuracy. In addition, ▲security has been strengthened with an administrator function that controls document download restrictions and access rights, and ▲convenience has been improved by providing additional functions such as translation, summarization, and code generation. This service achieved 94% answer accuracy and high user satisfaction after two months of preliminary testing.
“The establishment of this business-use generative AI service is just the beginning of the digital transformation of the Korea Water Resources Corporation through AI,” said Jeong Ha-dong, head of the Digital Management Office of the Korea Water Resources Corporation. “We will further develop more effective AI services in the future to provide innovative public services.”
Kim Kye-gwan, CEO of GridOne, said, “We are grateful to the Korea Water Resources Corporation for leading the innovation of AI work in public institutions,” adding, “The public sector is the most suitable for applying AI because it possesses a lot of data, and in the future, the difference in productivity compared to institutions that do not use AI in their work will be surprisingly large.”
