| Outline of Annual Research Achievements |
We have investigated algorithms based on Description Logics to advance the querying of VKG with an explainable similarity score and obtained outlines of the algorithms. We also studied algorithms that go beyond Description Logics. For example, how to inference with analogical reasoning between terminologies, how to complete knowledge graph with weighted knowledge graph embedding. These results can be used to support the implementation in our next step.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
We have obtained similarity algorithms for Description Logics. We are also conducting a preliminary study of using the algorithms for querying in our VKG system. Regarding our publication, we have published a conference paper at ICTAI, which is a leading IEEE-CS annual scientific meeting for three decades. In addition, we have submitted a journal paper to IEEE Access (Q1; under review) and another journal paper to SWJ (Q1; under review).

| Strategy for Future Research Activity |
As for our next step, we will mathematically prove our algorithm in order to conclude our mathematical framework for the VKG. At the same time, we are under the implementation of the investigating framework. The goal of this year is to ensure both theoretical and practical correctness of the system.

| Causes of Carryover |
We originally planed to participate the summer school ESSLLI (Europe) for broadening the network and obtaining necessary materials, knowledge, and skill. However, we terminated this plan due to the difficulty caused by COVID-19. Regarding the open access fee, the current status of our paper is still under review; thus, we would like to secure it for publication this year. Regarding technical books, we plan to purchase some this year while some of the remaining will be used to purchase computing devices for our experiment.
