  Our lives are ruled by events of varying importance ranging from simple
everyday occurrences to incidents of societal dimension. And a lot of effort is
taken to exchange information and discuss about such events: generally
speaking, stringent narratives are formed to reduce complexity. But when
considering complex events like the current conflict between Russia and Ukraine
it is easy to see that those events cannot be grasped by objective facts alone,
like the start of the conflict or respective troop sizes. There are different
viewpoints and assessments to consider, a different understanding of the roles
taken by individual participants, etc. So how can such subjective and
viewpoint-dependent information be effectively represented together with all
objective information? Recently event-centric knowledge graphs have been
proposed for objective event representation in the otherwise primarily
entity-centric domain of knowledge graphs. In this paper we introduce a novel
and lightweight structure for event-centric knowledge graphs, which for the
first time allows for queries incorporating viewpoint-dependent and narrative
aspects. Our experiments prove the effective incorporation of subjective
attributions for event participants and show the benefits of specifically
tailored indexes for narrative query processing.
