  • Building and enhancing the research network on the scholarly knowledge graphs in Germany 

Motivation for AIDA application

Building and enhancing the research network on the scholarly knowledge graphs in Germany 

I am currently researching and developing a research paper recommender system using scholarly knowledge graphs. Further developments on scholarly knowledge graphs might improve recommendations and enable to explain the rationale behind a recommendation to users. As forerunners in this field, German researchers are working on semantic web technologies and applications of those technologies to different disciplines including academics. Therefore, I applied for the AIDA program with the goal of building and enhancing my research network in Germany.



Fruitful discussion with researchers in Freiburg, Göttingen, and TIB.

At University of Freiburg, I discussed the quality of existing scholarly knowledge graphs with Dr. Michael Färber. We were even able to submit a joint paper to an international conference.

At University of Göttingen, I visited the eResearch Alliance formed by the Society for Scientific Data Processing (GWDG), which provides IT support services to the University of Göttingen, as well as the Göttingen State and University Library. I experienced an excellent research environment, where IT support service providers and libraries closely collaborated on research and development activities regarding persistent identifiers (PID) and digital humanities.

My last stop was at the German National Library of Science and Technology (TIB). There I received an introduction to the Open Research Knowledge Graph (ORKG), which is in the process of being developed at TIB. Furthermore, I had the chance to exchange views about information input methods and the overall future of structured knowledge systems. At a research seminar, I also had an opportunity to present my research regarding my research paper recommender system and discuss possibilities of utilizing the ORKG for its realization.



In the future, I want to contribute to the promotion of knowledge-centric scholarly communication utilizing the research network, which I developed during my stay. Furthermore, I am planning to expand it by seizing opportunities such as international conferences. In this regard, I agreed to apply for research grants in connection with ORKG as well as research paper recommender systems. Furthermore, I would like to apply for the DAAD re-invitation program for former scholarship holders.

After the Project  2020.3.26

Having consolidated the relation with institutes in Germany in previous project, I published several academic papers, especially on the Joint Conference on Digital Libraries (JCDL)*,  with co-authour Dr. Michael Färber.

I have also applied several research grants; among them, Inamori foundation Research Grant was successfully selected.  

In 2020, I was newly awarded by the DAAD-Kyoto Partnership Program 2020-21.  I wish to further extend my research and network through exchanging ECRs mutually between Kyoto and Germany.
