The communication of scholarly knowledge has hardly changed for centuries: It's document-based - once as a classic paper essay, now as a PDF. With around 2.5 million new research articles published every year, researchers are drowning in a flood of PDFs, many of which are not machine-readable. We are rethinking knowledge communication: Instead of static PDFs, we are relying on knowledge graphs. TIB is working with partners to link knowledge in a wide variety of forms - texts, images, videos, 3D models and much more - using knowledge graphs. These are intended to represent different research ideas, methods and results in a machine-readable way, so that completely new connections of knowledge come to light. The major global challenges require interdisciplinarity and the merging of knowledge. The Open Research Knowledge Graph developed by TIB can make this possible and revolutionize the sharing of knowledge.
