| Outline of Annual Research Achievements |
We have successfully implemented our prototype system called Virtual Knowledge Graph with Similar data (VKG-SIM). VKG-SIM is extended from the famous open source Ontop system and is implemented based on our algorithms for advancing the querying of VKG with an explainable similarity score. Thus, we could expect a high impact on the academic society and the industry. In addition, we have studied problems related to other KG systems.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
We have implemented our VKG-SIM system and conducted a preliminary analysis on its performance. Regarding our publication, we have published 1 journal paper (IEEE Access; Q1) and 5 international conference papers (ICAART, DSAI, KSE, ACIIDS, and ISWC).
|
| Strategy for Future Research Activity |
As for our next step, we completely develop our VKG-SIM system and evaluate based on real-world user scenarios in information retrieval. The goal of this year is to ensure practical correctness of the system and see how the proposed system can be applied beyond KG-based information retrieval.
|
| Causes of Carryover |
The conferences had arranged online participation; thus, the costs were reduced. In addition, we plan to submit an open access journal based on our system implementation; thus, we would like to secure it for our publication. To ensure the system correctness, the remaining budget will be also secured to hire a research assistant and extend my research collaboration with domestic and international partners with necessary business trips next fiscal year.
