Knowledge graphs gained popularity in recent years and have been useful for concept
visualization and contextual information retrieval in various applications. However …

The digital transformation of society affects all aspects of human life, offering new
opportunities but also creating challenges and risks. More tasks will be automated using …

Despite the maturity of commercial graph databases, little consensus has been reached so
far on the standardization of data definition languages (DDLs) for property graphs (PG) …

In this paper, we introduce a novel way of constructing concise causal histories (pathways)
to represent how specified structures are formed during simulation of systems represented …

Graph Transformation Units – An Overview* Page 1 Graph Transformation Units – An
Overview* Hans-Jörg Kreowski1, Sabine Kuske1, and Grzegorz Rozenberg2 1 University of …

We demonstrate how category theory provides specifications that can efficiently be
implemented via imperative algorithms and apply this to the field of graph transformation. By …

A foundational theory of compositional categorical rewriting theory is presented, based on a
collection of fibration-like properties that collectively induce and intrinsically structure the …

Sesqui-pushout (SqPO) rewriting along non-linear rules and for monic matches is well-
known to permit the modeling of fusing and cloning of vertices and edges, yet to date, no …

Abstract Model-driven engineering focuses on models as primary artifacts of the software
development process, which means programs are mainly generated by model-to-code …

We propose a new algebraic approach to graph transformation, called the Pullback-Pushout
(pbpo) approach, where we combine smoothly the classical modifications to a host graph …
