论文摘要
我们的生活是由从简单的日常事件到社会维度事件的重要性变化的统治。并付出了很多努力来交换信息并讨论此类事件：一般而言，形成了严格的叙述以降低复杂性。但是，在考虑诸如俄罗斯与乌克兰之间目前的冲突之类的复杂事件时，很容易看到这些事件不能仅仅被客观事实所掌握，例如冲突的开始或各自的部队规模。有不同的观点和评估需要考虑，对个人参与者所扮演的角色的不同理解等。那么，如何有效地代表这种主观和观点的信息以及所有客观信息？最近，已经提出了以事件为中心的知识图，用于在其他主要以实体为中心的知识图领域中的客观事件表示形式。在本文中，我们为以事件为中心的知识图介绍了一种新颖而轻的结构，该结构首次允许查询结合观点依赖和叙事方面的查询。我们的实验证明了为事件参与者有效纳入主观归因，并展示了针对叙事查询处理的专门定制索引的好处。
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.
