Expressiveness within Sequence Datalog
Heba Aamer, Jan Hidders, Jan Paredaens +1
Motivated by old and new applications, we investigate Datalog as a language for sequence databases. We reconsider classical features of Datalog programs, such as negation, recursio…
What Can Database Query Processing Do for Instance-Spanning Constraints?
Heba Aamer, Marco Montali, Jan Van den Bussche
In the last decade, the term instance-spanning constraint has been introduced in the process mining field to refer to constraints that span multiple process instances of one or sev…
Temporal graph patterns by timed automata
Amir Pouya Aghasadeghi, Jan Van den Bussche, Julia Stoyanovich
Temporal graphs represent graph evolution over time, and have been receiving considerable research attention. Work on expressing temporal graph patterns or discovering temporal mot…
On the expressive power of message-passing neural networks as global feature map transformers
Floris Geerts, Jasper Steegmans, Jan Van den Bussche
We investigate the power of message-passing neural networks (MPNNs) in their capacity to transform the numerical features stored in the nodes of their input graphs. Our focus is on…
