Hypertexts combine rich knowledge structures with ways of exploring them. Recently, knowledge graphs have emerged as a popular framework for knowledge representation. Knowledge graphs and related structured knowledge representations have been developed across many domains, ranging from digital humanities to scientific research and, more broadly, from Wikidata to the Google Knowledge Graph. This workshop will consider how knowledge graphs and related structured knowledge corpora can be matched with different types of user interaction. Hypertext offers a variety of modes for interacting with structured content such as argumentation and issue-based information systems, guided tours, and adaptive personalization. The workshop will consider how different modes of interaction can be applied to various domains, and conversely, how the knowledge structures need to be extended to support these modes. In addition, there are many open questions to be examined, such as extensions to ontologies, capturing the evolution of knowledge, and the relationship to LLMs.
