[Sci-Tech NOW] KAIST and Graphy Develop AkashicDB to Cut AI Hallucinations and Boost Accuracy

■ KAIST introduced on the nineteenth {that a} analysis workforce led by Professor Kim Min-soo of the School of Computing, along with school startup firm “Graphy,” has developed the next-generation database know-how “AkashicDB” and a brand new retrieval-augmented technology method “OmniRAG.” AkashicDB is designed in order that vector, graph, and relational DB features may be executed in an built-in method inside a single database administration system. OmniRAG was developed based mostly on AkashicDB. By concurrently leveraging semantic info in paperwork, relationships between entities, and structured information, it enhances the reply accuracy of generative synthetic intelligence (AI). Experimental outcomes present that it improves AI reply accuracy by up to 78% and processing velocity by up to 20 instances, considerably mitigating hallucination points. Professor Kim mentioned, “AkashicDB is a next-generation database technology for the era of AI agents, and we expect it to serve as a core data infrastructure in areas that require a high level of reliability, such as defense, manufacturing, finance, law, and science and technology.”

■ Ulsan National Institute of Science and Technology (UNIST) introduced on the nineteenth that it ranked 299th within the “QS World University Rankings 2027,” launched on the 18th, climbing 11 spots from the earlier 12 months. It demonstrated its analysis competitiveness by rating thirty second worldwide (99.3 factors) in citations per school and getting into the worldwide prime 100 within the school–scholar ratio. Its educational popularity rose by 72 locations and employer popularity by 19 locations, main to an evaluation that its worldwide recognition and trade analysis have each improved. In the just lately launched “Nature Index 2026,” UNIST rose 28 locations from the earlier 12 months. UNIST analyzed that the current growth of worldwide joint analysis and analysis networks has positively contributed to the rise in popularity. President Park Jong-rae mentioned, “Based on our research competitiveness, we will strengthen international collaboration and networks to enhance our status as a global research-centered university.”

■ Daegu Gyeongbuk Institute of Science and Technology (DGIST) introduced on the nineteenth that it has achieved first place in Korea for the second consecutive 12 months within the “citations per faculty member” class within the “QS World University Rankings 2027,” launched on the 18th. “Citations per faculty member” is an indicator that evaluates how regularly papers revealed by a college’s researchers are cited by researchers all over the world. DGIST recorded 409.5 citations per school member over 5 years, far exceeding the world common of 59.9 by sixfold, and obtained the very best attainable rating of 100 for this indicator for the second 12 months in a row. Among Korea’s science and engineering specialised universities, DGIST is the one establishment to file the highest rating for 2 consecutive years. President Lee Geon-woo mentioned, “This is the result of all members of DGIST devoting themselves in unison to research and innovation,” including, “Based on our research competitiveness recognized worldwide, we will further strengthen DGIST’s unique, differentiated convergence research and leap forward as a global research-centered university leading the AI era.”

■ Gwangju Institute of Science and Technology (GIST) introduced on the nineteenth that it has been chosen as an official companion of the worldwide training program “Arm School Program” and will totally launch the “GIST–Arm School Semiconductor Design Education Program.” This program is a follow-up venture to a memorandum of understanding GIST signed with Arm in February, and goals to domesticate practice-oriented professionals in semiconductor design by using Arm’s official academic content material and design property. The program targets college students in a minimum of their fourth 12 months of undergraduate research who want to discover employment within the semiconductor area, graduates (or potential graduates), and staff, with 30 contributors chosen for every monitor. This 12 months’s curriculum consists of a complete of seven tracks: Introduction to Arm-Based Computer Architecture (Track 1); Arm-Based Embedded Systems (Track 2); VLSI Fundamentals (Track 3); SoC Design with Arm Cortex-M (Track 4); RTL Design and SoC Term Project (Track 5); Physical Design Front-End (Track 6); and Physical Design Back-End (Track 7). Recruitment is at present underway for Tracks 1 and 2. Registration for Track 1 is open till June 22. Application deadlines for every monitor are one week earlier than the beginning of lectures and will shut sequentially. Tracks 1–4 are the primary formally licensed Arm academic programs to be provided in Korea, and contributors who full them will obtain a certificates of completion.

■ Gwangju Institute of Science and Technology (GIST) introduced on the nineteenth that the Power Grid Research Center at its Next Generation Energy Research Institute has developed and launched freed from cost a simulation mannequin, the “GIST 2217-Bus Test System,” which implements Korea’s whole energy grid on a pc utilizing solely publicly obtainable information. It is evaluated as having established a basis that allows home researchers to conduct research in an atmosphere reflecting the traits of the particular Korean energy system. The constructed mannequin represents a transmission community of roughly 3,700 strains, incorporating the grid connecting main energy crops and substations nationwide in addition to the interconnection to Jeju Island. Unlike abroad energy grid fashions that researchers have primarily used to date, a key characteristic of this mannequin is that it’s a “Korea-specific” system reflecting the construction and traits of the Korean energy system. It has been verified to carry out steady calculations even below situations assuming peak hours in summer time, when electrical energy consumption is excessive, thereby securing a degree of reliability appropriate for precise energy grid analysis. An interactive map can also be supplied, permitting customers to instantly view the grid construction in an internet browser. Model information and associated supplies can be found freed from cost through the GIST Power Systems Laboratory web site (psl.gist.ac.kr).
