Knowledge bases allow effective access paths in digital libraries.Here users can specify their information need as graph patterns for precise searches and structured overviews (by allowing variables in queries). But especially when considering textual sources that contain narrative information, i.e., short stories of interest, harvesting statements from them to construct knowledge bases may be a serious threat to the statements' validity. A piece of information, originally stated in a coherent line of arguments, could be used in a knowledge base query processing without considering its vital context conditions. And this can lead to invalid results. That is why we argue to move towards narrative information access by considering contexts in the query processing step. In this way digital libraries can allow users to query for narrative information and supply them with valid answers. In this paper we define narrative information access, demonstrate its benefits for Covid 19 related questions, and argue on the generalizability for other domains such as political sciences.

“…Most works in this direction fall into one of two categories: First, the unsupervised extraction of narrative patterns, i.e., script learning [21] or inferring event chains [6,7]. Secondly, the top-down approach, i.e., modeling narrative structures and verify them against a (heterogeneous) knowledge repository [15,16]. Our work falls into the second category.…”

It's the Same Old Story! Enriching Event-Centric Knowledge Graphs by Narrative Aspects

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 eventcentric 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.

“…A remedy might be the use of narrative information access to bypass the necessary integration of different sources. In [23], narratives are defined by directed edge-labeled graph patterns involving entities (things and concepts), events (state or state changes), literals (values), and their respective relationships (properties, temporal, and causal predicates, etc. ).…”

“…This evidence forms so-called narrative bindings connecting each relationship against a concrete piece of information stated in some knowledge repository, i.e., any form of data storage (e.g., relational databases, knowledge graphs, data sets, etc.). In previous works we formulated a conceptual model [23] for narrative information access, discussed the binding process from a technical perspective [24], showed how queries can be processed over collections of scientific publications [25], and discussed conceptual problems like context compatibility when answering queries over independent knowledge bases [26].…”

Linking Theory and Practice of Digital Libraries

Designing keyword-based access paths is a common practice in digital libraries. They are easy to use and accepted by users and come with moderate costs for content providers. However, users usually have to break down the search into pieces if they search for stories of interest that are more complex than searching for a few keywords. After searching for every piece one by one, information must then be reassembled manually. In previous work we recommended narrative information access, i.e., users can precisely state their information needs as graph patterns called narratives. Then a system takes a narrative and searches for evidence for each of its parts. If the whole query, i.e., every part, can be bound against data, the narrative is considered plausible and, thus, the query is answered. But is it as easy as that? In this work we perform case studies to analyze the process of making a given narrative plausible. Therefore, we summarize conceptual problems and challenges to face. Moreover, we contribute a set of dimensions that must be considered when realizing narrative information access in digital libraries.
