Integrated care approaches are becoming increasingly relevant with the current aging population. In the context of an integrated healthcare project, we developed a smart adaptive case management system for professionals that is currently being used for clinical trials. In this paper, we present the modeling requirements for integrated healthcare applications and use them to categorize and compare existing implementation approaches used in practice. [link]

The paper An Agile Framework for Modeling Smart City Business Ecosystems  was presented at the International Conference on Enterprise Information Systems 2018 (ICEIS 2018), Funchal, Madeira, Portugal. The authors (Anne Faber, Adrian Hernandez-Mendez, Sven-Volker Rehm and Florian Matthes) describe a collaborative modeling process, which empowers end-users to manage the business ecosystem models and underlying data. The paper has won the ICEIS 2018 Best Paper Award.

In large software engineering projects, designing software systems is a collaborative decision-making process where a group of architects and developers make design decisions on how to address design concerns by discussing alternative design solutions. For the decision-making process, involving appropriate individuals requires objectivity and awareness about their expertise. In this paper, we propose a novel expert recommendation system that identifies individuals who could be involved in tackling new design concerns in software engineering projects. The approach behind the proposed system addresses challenges such as identifying architectural skills, quantifying architectural expertise of architects and developers, and finally matching and recommending individuals with suitable expertise to discuss new design concerns. To validate our approach, quantitative evaluation of the recommendation system was performed using design decisions from four software engineering projects. The evaluation not only indicates that individuals with architectural expertise can be identified for design decision making but also provides quantitative evidence for the existence of personal experience bias during the decision-making process.

Abstract:

An increasing number of large organizations are adopting agile and lean methods at larger scale for building complex software systems. One major critique of agile development and in particular of large-scale agile development is the neglect of proper architecting assistance in such development efforts. On the one hand, emergent architecture design may require excessive redesign efforts in large systems, while on the other hand, big upfront architecture delays the starting point of implementation. Domain-driven Design (DDD) addresses this problem by providing means for evolving the architecture of complex systems in an agile way. We describe how DDD can support large-scale agile development based on a conducted case study in a large insurance company with three agile teams. Furthermore, we present a framework for large-scale agile development that is largely based on Large-Scale Scrum and incorporates strategic and tactical DDD.

The team of Florian Matthes, consisting of Ingo Glaser, and Bernhard Waltl, has published their recent results on Named Entity Recognition, Extraction, and Linking in German Legal Documents at the 21st international legal informatics symposium (IRIS). The paper is going to be presented at the conference from 22-24 February 2018, Salzburg.
