The approach of creating a visual research topic map for materials science researchers from a large collection of archived research papers using natural language processing (NLP) has become of more importance with the expansion of research information. Visualization of research topics shows the connection of researchers to related topics aiming to find potential collaborators, which can increase potential research cooperations. Presentation from "VIVO Talks!" with Dr. Sae Dieb, Energy Materials Design Group, will present the use of this approach on SAMURAI, a directory service for the researchers of the National Institute for Materials Science (NIMS), Japan. “VIVO Talks!” is organized by the project team of VIVO Research Information Platform for the Berlin University Alliance. Within this alliance, a four-member project team is currently developing a federated platform to present information of researchers, their research and activities using the open source software VIVO. This project is funded by the Federal Ministry of Education and Research (BMBF) and the state of Berlin within the framework of the Excellence Strategy of the Federal Government and the Länder.
