Tóm tắt

The problem of lazy visualization of ontological graphs has certain constraints. Visualization of structures that contain blank nodes is especially challenging. In this paper, we propose an approach to visualization of these structures that is implemented in Ontodia, analyze the limitations of this approach, and consider some alternative solutions.
