Special issue on Knowledge Graph Construction

Call for papers: Special Issue on

Knowledge Graph Construction

This special issue aims to explore the latest research trends and enhance the state of the art in the field of knowledge graph construction from semi-structured data. While many methods and systems were proposed to construct knowledge graphs from existing semi-structured data stored in databases or available on the Web, knowledge graph construction is a complex task and there are still many open research questions.

Knowledge graphs (KGs) are key to the adoption of the Semantic Web. This special issue should provide a comprehensive overview of the latest research trend and inspire further research in this exciting and rapidly evolving area. We welcome original research papers that propose novel techniques, models, and frameworks for generating high-quality and reliable knowledge graphs from structured and semi-structured data, such as relational databases, CSV, XML, JSON etc.

Meeting the challenges associated with constructing knowledge graphs necessitates the investigation of theoretical concepts and the design of efficient systems and methodologies. Many declarative approaches were proposed, yet they lack corresponding formalizations. Although these declarative methods initially sparked the design of virtualisation systems,they did not gain as much traction as well in the case of heterogeneous data where a multitude of materialisation systems emerged to efficiently construct knowledge graphs. Even among materialisation systems, there is still ample space for enhancements and improvements but systematic evaluation methods were not proposed yet.

Knowledge graph construction was seen as the responsibility of a single entity (typically the data owner). However, with the advent of data spaces, knowledge graph construction has evolved entailing a whole new range of challenges, such as collaborative knowledge graph construction or conformance to a commonly agreed model. While early approaches have predominantly focused on declarative methods and systems to support users with the declaration of rules for knowledge graph construction, there has been lately a growing interest in leveraging large language models (LLMs) and machine learning (ML) algorithms in general in the field, opening up new research avenues for constructing knowledge graphs. Naturally, when machine learning comes into play, additional considerations, such as explainability, reproducibility and replicability become relevant.

Contributions along the aforementioned (but not limited to) directions are considered for the proposed special issue on knowledge graph construction, including theoretical investigations, lessons learned, and observations from in-use experiences.
