Business Process Management (BPM) is a critical field for keeping business operations running soundly; spotting inefficiencies and potentially malicious activity in processes early matters even more as the pace of business accelerates. This need gave rise to the research area known as "business process anomaly detection." This paper, prepared by the Next4biz R&D Center together with Akdeniz University, takes the team's earlier work on graph-based anomaly detection one step further.

In the study, process data is represented as a graph and a Graph Autoencoder (GAE) architecture built with different graph convolution operators is designed; the goal is to raise performance through the reconstruction of edge features and advanced linear networks. The authors systematically compare 3 different encoder architectures and 4 different decoder options across six separate datasets. The publisher's abstract does not state the source of the datasets (whether or not they are Next4biz product data).

The results differ markedly depending on the encoder-decoder combination: in anomaly detection the F1 score ranges from 0.219 to 0.674. This wide range clearly shows how much the architectural choices affect the outcome.

The paper was presented at the 7th International Congress on Human-Computer Interaction, Optimization and Robotic Applications (ICHORA 2025), held in Ankara on May 23–24, 2025, and was published by IEEE in the congress proceedings (pp. 1–6). The authors are Teoman Berkay Ayaz, Rabia Çevik and Akhan Akbulut (Next4biz R&D Center) together with Alper Özcan (Akdeniz University, Computer Engineering).
