This thesis conducts a text and network analysis of criminological files. The specific focus during the research is the field money laundering. The analysis showed the most important concepts present in the text which were classified in eleven different classes. The relationships of those concepts were analysed using ego networks, key entity identification and clustering. Some of the statements given about money laundering could be validated by the findings of this analysis and their interpretation. Specific concepts like banks and organizations as well as foreign subsidiaries were identified. Aggregating these concepts with the statements in chapter 1.4.3 on the circular process of money laundering it can be stated that different organizations and individuals, present in the criminological files, were placing money through different banks, organizations and investments in the legal financial market. At last this thesis tries to validate the benefits of the used tools for the kind of conducted research process. An estimation on ORA's and Automap's applicability for this kind of research is given in the end.
Massenprozessmanagement
(2015)
This dissertation answers the research question which basically suitable approaches and which necessary information technologies are to be considered for the management of business processes in large amounts (Mass Business Process Management, MBPM) in service companies. It could be shown that for the execution of mass processes a special approach that uses methods of the manufacturing industry is necessary. The research aim to develop an MBPM approach for service companies was accomplished by using the Design Science Research approach and is explained in this dissertation in consecutive steps. For the development of the MBPM approach a longitudinal indepth case study was conducted with a business process outsourcing provider to gain insights from his approach. Outsourcing providers have to produce their services in a very efficient and effective way, otherwise they will not be able to offer their products at favorable conditions. It was shown that the factory-oriented approach of the out-sourcing service provider in the observation period of ten years was suitable to execute mass processes of highest quality, at constantly decreasing prices with less and less people.
The assumed need for research concerning MBPM was verified on the basis of an extensive literature research based on the Journal Rating VHB-Jourqual and other literature sources. As many approaches for the introduction of BPM were found, a selection of BPM approaches was analyzed to gain further insights for the development of the MBPM approach. Based on the analysis and the comparison of the different BPM approaches as well as the comparison with the approach of the process outsourcing provider it was found, that BPM and MBPM differ in many aspects. MBPM has a strong operational focus and needs intensive IT support. The operative focus mainly shows in the operative control of processes and people as well as in the corresponding high demands on process transparency. With detailed monitoring and fine grained process measurements as well as timely reporting this process transparency is achieved. Information technology is needed for example to conduct process monitoring timely but also to give internal as well as external stakeholders the desired overview of the current workload and of the invoicing of services.
Contrary to the approach of the process outsourcing provider it could also been shown, that change management can influence the implementation, the continuous operation and the constant change associated with MBPM in a positive way.
In this work a framework is developed that is used to create an evaluation scheme for the evaluation of text processing tools. The evaluation scheme is developed using a model-dependent software evaluation approach and the focus of the model-dependent part is the text-processing process which is derived from the Conceptual Analysis Process developed in the GLODERS project. As input data a German court document is used containing two incidents of extortion racketeering which happened in 2011 and 2012. The evaluation of six different tools shows that one tool offers great results for the given dataset when it is compared to manual results. It is able to identify and visualize relations between concepts without any additional manual work. Other tools also offer good results with minor drawbacks. The biggest drawback for some tools is the unavailability of models for the German language. They can perform automated tasks only on English documents. Nonetheless some tools can be enhanced by self-written code which allows users with development experience to apply additional methods.
This research examines information audit methodologies and information capturing methods for enterprise social software which are an elementary part of the audit process. Information auditing is lacking of a standardized definition and methodology because the scope of the audit process is diversified and dependent on the organization undertaking the audit. The benefits of information auditing and potential challenges of Enterprise 2.0 the audit can overcome are comprehensive and provide a major incentive for managers to conduct an audit. Information asset registers as a starting point for information auditing are not specifically focusing on social software assets. Therefore this research pro-ject combines asset registers from different areas to create a new register suitable for the requirements of Enterprise 2.0. The necssary adaptations caused by the new character of the assets are minor. The case study applying the asset register for the first time however reveals several problematic areas for information auditors completing the register. Rounding up the thesis a template is developed for setting up new work spaces on enterprise social software systems with appropriate metadata taking into account the meaningful metadata discovered in the asset register.
