Towards reasoning over knowledge graphs under aleatoric and epistemic uncertainty

The objective of this short article is to propose a research orientation to address the international Knowledge Graph Reasoning Challenge (IKGRC). The IKGRC consists in solving mysterious crimes and providing a reasonable explanation based on open knowledge graphs, which represent the case, background, and characters of some Sherlock Holmes novels.The suggestion of this paper is to use the framework of the belief functions, well adapted to the consideration of different uncertainties and the management of conflicting information.
