Center node: "accbench a framework for comparing causality algorithms"
  Abstract: Modern socio-technical systems are increasingly complex. A fundamental problem is that#R##N#the borders of such systems are often not well-defined a-priori, which among other problems#R##N#can lead to unwanted behavior during runtime. Ideally, unwanted behavior should#R##N#be prevented. If this is not possible the system shall at least be able to help determine#R##N#potential cause(s) a-posterori, identify responsible parties and make them accountable for#R##N#their behavior. Recently, several algorithms addressing these concepts have been proposed.#R##N#However, the applicability of the corresponding approaches, specifically their effectiveness#R##N#and performance, is mostly unknown. Therefore, in this paper, we propose ACCBench, a#R##N#benchmark tool that allows to compare and evaluate causality algorithms under a consistent#R##N#setting. Furthermore, we contribute an implementation of the two causality algorithms#R##N#by [7] and [6] as well as of a policy compliance approach based on some concepts of [16].#R##N#Lastly, we conduct a case study of an Intelligent Door Control System, which exposes concrete#R##N#strengths and weaknesses of all algorithms under different aspects. In the course of#R##N#this, we show that the effectiveness of the algorithms in terms of cause detection as well as#R##N#their performance differ to some extent. In addition, our analysis reports on some qualitative#R##N#aspects that should be considered when evaluating each algorithm. For example, the#R##N#human effort needed to configure the algorithm and model the use case is analyzed.
