Dear all,
We are pleased to announce the Multi-dimensional Knowledge Graphs (MKG) Workshop, a Barstuhl-format workshop taking place on Sunday, October 25, 2026, as part of ISWC 2026 in Bari, Italy.
Cultural heritage and Digital Humanities data rarely fit a single, monolithic notion of truth. A manuscript's attribution, a monument's dating, or a historical event's interpretation may be described differently across scholarly traditions, curatorial practices, community memory, or competing hypotheses — and these differences are often exactly what makes the data valuable. Yet mainstream Knowledge Graphs still tend to flatten such statements into a single asserted layer, losing provenance, perspective, uncertainty, and disagreement in the process.
This workshop introduces Multi-dimensional Knowledge Graphs (MKGs) as an umbrella paradigm for contextual, perspectival, and temporal knowledge representation. We are particularly interested in bringing the Digital Humanities and Cultural Heritage community into dialogue with formal and engineering perspectives: models like CRMInf and other argumentation/inference extensions to CIDOC-CRM, competing scholarly interpretations, multi-perspective annotation, and the representation of evolving or contested attributions are all central to the discussion.
Through lightning pitches and collaborative breakout sessions, the workshop aims to surface shared patterns across these traditions and the wider Semantic Web toolbox (reification, named graphs, RDF-star/RDF 1.2, provenance vocabularies, nanopublications, and more). The main outcome will be a community-drafted framework document, laying the foundation for an MKG white paper and a potential future Dagstuhl seminar.
Topics include:
- Representing scholarly interpretations, hypotheses, and argumentation (e.g. CRMInf-style inference and belief modelling)
- Multi-perspective and multi-viewpoint representation of cultural heritage data
- Formal models for multi-dimensional assertions and conflicting viewpoints
- Query, storage, and indexing strategies for contextual KGs at scale
- Benchmarks, design patterns, and use cases across Digital Humanities, Cultural Heritage, and the Life Sciences
