The Narrative Building and Visualising Tool (NBVT) is a semi-automatic tool to construct and visualise narratives, intended as semantic networks of events related to each other through semantic relations. This tool obeys an ontology for narratives we developed. NBVT uses Wikidata as a reference knowledge base for importing entities, and Wikimedia Commons as an external source of images. The user of NBVT can build each event of the narrative and attach to them the participating entities from Wikidata, or they can define new ones not present in the knowledge base. NBVT assigns IRIs (Internationalised Resource Identifiers) to the selected instances and facilitates the construction of events based on these instances, and their linking to form narratives. The knowledge collected by the tool is exported as Linked Data, and the knowledge is automatically saved, behind the scenes, as an OWL (Web Ontology Language) graph in a Blazegraph triple store. Based on this representation, the tool allows the user to visualise the knowledge in the graph in simple formats like tables, network graphs, and timelines, using SPARQL queries.
