Abstract
The usage of the term Knowledge Graph (KG) has gained significant
popularity since 2012, when Google introduced its own knowledge graph,
and how they used it to enhance their searches and question answering
systems. While various definitions and interpretations for knowledge
graphs have been presented, what remains consistent is that knowledge
graphs are commonly used with reasonsers to make inferences about data,
based on assertions and axioms written by human experts. But knowledge
graphs, which store complex, multi-dimensional data contain hidden
patterns and trends that cannot be explored simply using reasoners. In
such a case it becomes necessary to extract parts of the knowledge graph
(focusing on the instances related to one property at a time) and
analyze them individually in order to conduct a focused but tractable
exploration of the domain. In this presentation, we present one way to
gain insights from knowledge graphs, using network science. To achieve
this goal, we have formalised the partitioning of knowledge graphs to
unipartite knowledge networks, and present various ways to explore and
analyse such knowledge networks to form scientific hypotheses, gain
scientific insights and make discoveries.
