Conference Paper
We provide a first systematic account of opportunities and limitations of anti-money laundering (AML) in Bitcoin, a decentralized cryptographic currency proliferating on the Internet. Our starting point is the observation that Bitcoin attracts criminal activity as many say it is an anonymous transaction system. While this claim does not stand up to...

Full-text available
Proof-of-Work (PoW), a well-known principle to ration resource access in client-server relations, is about to experience a renaissance as a mechanism to protect the integrity of a global state in distributed transaction systems under decentralized control. Most prominently, the Bitcoin cryptographic currency protocol leverages PoW to 1) prevent dou...

Analyzing conceptual models such as process models, data models, or organizational charts is useful for several purposes in information systems engineering (e.g., for business process improvement, compliance management, model driven software development, and software alignment). To analyze conceptual models structurally and semantically, so-called...
Chapter
Industrielle Dienstleistungen spielen heute eine wichtigere Rolle denn je zur Erschließung neuer Ertragspotenziale bei steigendem Wettbewerbsdruck für Industriegüterhersteller. Die Erbringung derartiger Dienstleistungen wird dabei in der industriellen Praxis nur unzureichenden Effizienzbeobachtungen unterzogen. Gefordert ist daher ein ganzheitliche...
Conference Paper
If Bitcoin becomes the prevalent payment system on the Internet, crime fighters will join forces with regulators and enforce blacklisting of transaction prefixes at the parties who offer real products and services in exchange for bitcoin. Blacklisted bitcoins will be hard to spend and therefore less liquid and less valuable. This requires every rec...
Article
Analysing conceptual models is a frequent task of Business Process Management (BPM). Application scenarios include comparing or integrating business processes, checking business processes for compliance or weaknesses, and customizing conceptual models for different audiences. Many companies maintain large model collections. Analysing such collectio...

Graphical models and general purpose inference algorithms are powerful tools for moving from imperative towards declarative specification of machine learning problems. Although graphical models define the principle information necessary to adapt inference algorithms to specific probabilistic models, entirely model-driven development is not yet poss...
Conference Paper
This paper outlines a graphical model query approach based on graph matching. It consists of a graphical query specification language and a matching algorithm based on graph matching that takes the query as input and returns all matches found in a model to be searched. The graphical query specification language can be used to draw model queries muc...

Management studies and organization science use the concept of organizational routines when investigating collective recurrent activity patterns. Process mining is a sub-field of business process management that analyses event log data from information systems that signifies accomplished activities for the discovery, conformance checking and enhanc...
Conference Paper
Full-text available
We introduce a pattern matching approach for conceptual models suitable for a number of model analysis scenarios like process weakness detection, process compliance checking, syntax verification and model translation. The approach does not depend on any particular modeling language which is achieved by treating conceptual models as labeled graphs....
Article
With respect to the scientific method, reproducing empirical research is a necessary step to develop generalizable knowledge. However, in service productivity measurement and managerial science in general, little attention seems to be paid on replicating empirical studies. One reason could be that many studies do not report their data and methodolo...
Article
Full-text available
Meta-modelling tools have been proposed to facilitate the development and adoption of domain-specific modelling languages (DSMLs). These languages specify a set of domain-specific concepts and assign diagrammatic representations to them. A considerable amount of work has been done to develop meta-modelling tools ensuring syntactical correctness of...
Conference Paper
The co-creation of value involving service provider and service customer is one of the most widely acknowledged properties of ‘service’. From an operations view, a central challenge is to organize the co-creation of service(s) in the most efficient way. Previous literature in supply chain management and economics is focused on developing various si...
Article
Service-oriented systems are deployed by companies to support busi-ness processes, especially in inter-organizational collaborative settings. Process mining provides techniques to visualize and understand the emergent behavior in such systems based on data, as compared to what employees believe it is like. In highly unstructured settings however, t...
Conference Paper
Pattern detection serves different purposes in managing large collections of process models, ranging from syntax checking to compliance validation. This paper presents a runtime analysis of four graph-theoretical algorithms for (frequent) pattern detection. We apply these algorithms to large collections of process and data models to demonstrate tha...
Conference Paper
Business Process Management (BPM) is a topic with growing relevance for businesses as well as public organisations. Until today, the analysis part of a BPM cycle is mostly done manually. Process modelling methods are not designed to allow for automated analysis. Our aim is to show that meaningful weakness patterns that support semi-automatic analys...
Conference Paper
http://prob-miner.uni-muenster.de/ The paper explores how reading experience of scientific publications can be improved through interactive web content. Constructivist learning theories advertise active involvement of learners as a key requirement for successful teaching. Analogously, we argue that active involvement of readers can facilitate the p...

Assuring compliant business processes is an important task of business process management, which is commonly supported by the use of business process models. As every compliance rule corresponds with a typical structure, the detection of those corresponds to a pattern matching problem. More specifically, we encounter the problem of subgraph isomorp...
Conference Paper
The rise of the service economy is increasingly reflected in the IS discipline. Since services depend on a co-creation of value between service providers and customers, productivity measurement needs to account for both points of view. Contrasting this evolution, current productivity management concepts often remain limited to the firm instead of f...
Conference Paper
A service is a transformation process that creates a set of outputs from a set of inputs. The ratio of these two quantities defines a measure of productivity, which can be made operational using Data Envelopment Analysis (DEA), a well-known method from the field of operations research. Before such an analysis can be conducted, appropriate factors h...
