KGC Call for Papers

More and more knowledge graphs (KGs) are constructed for private use, e.g., Google, or public use, e.g., DBpedia, Wikidata. While many solutions were proposed to construct KGs from existing data on the Web, there are still no mature systems to automate the rules definition nor systematic evaluations to compare the performance and resource usage of the different systems independently of the mapping language they use or the way they construct the knowledge graph (materialization or virtualization). Addressing the challenges related to KG construction requires both the investigation of theoretical concepts and the development of systems and methods for their evaluation.

The Knowledge Graph Construction Workshop (KGCW) will continue being the forum for novel techniques, frameworks, architectures, and tools for declarative KGC languages such as RML. The Knowledge Graph Construction challenges focusing on KG generation efficiency have matured after several successful iterations. Now, the community has recognized a need to assess compliance with the new RML modules to move forward.

This edition will focus on these aspects and the assessment thereof, which enables the workshop to collect contributions from a wide range of topics such as the role of generative LLMs in (declarative) KG Generation, automation and planning of KG processes, and the role of human stakeholders in KG processes. The workshop includes a keynote, (research, in-use, experience, position, system) paper presentations, demo jam, and break-out discussions.

Our goal is to provide a venue for scientific discourse, systematic analysis, and rigorous evaluation of languages, techniques, and systems, as well as practical and applied experiences and lessons learned for constructing knowledge graphs from academia and industry. The workshop complements and aligns with the activities of the W3C Community Group on KG construction.

Keynote

Knowledge Graph Construction at metaphacts: Reflections on a Decade of Innovation and a Vision for the Future Peter Haase

Ten years ago, I founded metaphacts with the mission to empower organizations in building and leveraging their own knowledge graphs. In this keynote, I will share insights and lessons learned over a decade of working on knowledge graph construction — spanning our experiences with product development, community engagement, methodologies, best practices, and real-world application examples. I will also offer my perspective on the evolving landscape of Knowledge Graph Construction and outline key trends and opportunities that I believe will shape its future.

About the speaker

Responsive image

Peter has a long history in the Semantic Web and Knowledge Graph community, his first contacts with semantic technologies dating back 25 years. In 2006, Peter obtained his PhD from the University of Karlsruhe (now KIT). In 2014, Peter founded metaphacts, focusing on enterprise knowledge graphs. In his current role, he is steering the R&D efforts at metaphacts, now part of the Digital Science group, with an increased interest in scientific knowledge graphs.
