Divide and Conquer the EmpiRE: A Community-Maintainable Knowledge Graph of Empirical Research in Requirements Engineering
Oliver Karras, Felix Wernlein, Jil Kl\"under, S\"oren Auer

TL;DR
This paper demonstrates how the Open Research Knowledge Graph can be used to build a community-maintainable, comprehensive knowledge graph of empirical research in requirements engineering, promoting sustainable literature reviews.
Contribution
It introduces KG-EmpiRE, a knowledge graph of empirical RE research built on ORKG, enabling ongoing community-driven updates and synthesis of research evolution.
Findings
Analyzed 570 papers from RE conferences (2000-2022).
Answered 16 out of 77 competency questions about empirical research.
Showed positive trends but identified areas for future improvement.
Abstract
[Background.] Empirical research in requirements engineering (RE) is a constantly evolving topic, with a growing number of publications. Several papers address this topic using literature reviews to provide a snapshot of its "current" state and evolution. However, these papers have never built on or updated earlier ones, resulting in overlap and redundancy. The underlying problem is the unavailability of data from earlier works. Researchers need technical infrastructures to conduct sustainable literature reviews. [Aims.] We examine the use of the Open Research Knowledge Graph (ORKG) as such an infrastructure to build and publish an initial Knowledge Graph of Empirical research in RE (KG-EmpiRE) whose data is openly available. Our long-term goal is to continuously maintain KG-EmpiRE with the research community to synthesize a comprehensive, up-to-date, and long-term available overview of…
