Collaboration is a rich source of innovation and growth and it is the goal of the Collaborative European Research Conference (CERC 2016) to foster collaboration among friends and colleagues across disciplines and nations within Europe. CERC emerged from a long-standing cooperation between the Cork Institute of Technology, Ireland and Darmstadt University of Applied Sciences, Germany.
CERC has grown to include more well-established partners in Germany (Hochschule Karlsruhe and FernuniversitÃ¤t Hagen), United Kingdom, Greece, Spain, Italy, and many more.

CERC is truly interdisciplinary, bringing together new and experienced researchers from science, engineering, business, humanities, and the arts. At CERC researchers not only present their findings as published in their research papers. They are also challenged to collaboratively work out joint aspects of their research during conference sessions and informal social events and gatherings.

Traditional faceted search systems often suffer from a lack of usability; furthermore facets are often static and independent from the search result set. In this paper, we present a dynamic semantic topical faceting approach. It uses a pie menu called topic pie that allows visualisation of facets and user interaction. Depending on the search query, the topic pie presents a set of topics and major topics which help the user to drill down the search result set to relevant objects efficiently as well as to browse exploratively through the collection. The underlying algorithm optimises the conflicting goals relevance and diversity while avoiding information overload. It reveals a good performance on large data sets. As our use-case, we chose literature research in scientific libraries. An evaluation shows major advantages of our approach compared to state-of-the-art faceted search techniques in nowadays library portals.

We present two working applications that apply the presented methods. Our promising results could contribute to a better understanding of online collections on di erent device classes, like smartphones, tablets and large screen sized devices, and thus enrich the experience of digital humanities.

This paper presents an automatic guidance system that supports users in their literature research with a stepwise
refinement process, based on their needs. Algorithms operate on various different data sets, including valuable world knowledge in form of Linked Open Data, which is streamlined and indexed by a Semantic Extraction, Transform and Load process. Search results are ...

of museum's website visitors with a unique experience that cannot be reproduced in the museum itself. We aim at providing a continuous and lasting experience, without the emphasis of a single, fi nal result - a process we call digital strolling. The view supports this process by displaying results as a path on which the user strolls. To enable the user to find new and unexpected inspiration, recommendations to related exhibits are proposed in di erent dimensions to vary the user's path. The common
approach of image retrieval as the sole method to generate recommendations of related exhibits is not sucient. Authored tagging is still the better but more costly solution. The proposed approach claims to fill the gap between current digital museums and the needs of the digital museums' visitors.

Such languages and environments are not well-integrated and lack common abstraction mechanisms. This paper presents a concept framework to alleviate those problems. This is demonstrated by a complex sample application: reasoning over business process models.

For sd&amp;amp;m, knowledge management is a strategic investment with the goal to acquire the right knowledge, to make it accessible to all employees, and to increase their proficiency. Effective knowledge management depends on the right combination of the

In Quasar werden technische Dienste mittels Schnittstellen spezifiziert. Diese Schnittstellen wurden bei sd&m in Form von technischen Komponenten, genannt Quasar-Komponenten, implementiert. Quasar-Komponenten verwenden Open Source Klassenbibliotheken und sind selbst Open Source. Quasar-Architektur, -Komponenten und die Expertise ihrer Nutzung bilden ein Lösungspaket, welches bereits in vielen umfangreichen Projekten bei sd&m erfolgreich eingesetzt wurde.

In dem Artikel wird eine alternative Definition vorges-tellt, welche den Service in den Kontext der Geschäftsarchitektur eines Unter-nehmens stellt. Zusammenhänge zu den in der Softwaretechnik etablierten Be-griffen werden aufgezeigt. 1 Einleitung Service-Orientierte Architektur (SOA) ist das derzeit am meisten diskutierte Paradigma zur Gestaltung von IT-Anwendungslandschaften. Hunderte von Publika-tionen (z.B. [BBF+05], [Erl04], [KBS04], [RHS05], [Woo04], um nur einige prominente zu nennen) de-monstrieren, dass das Thema derzeit noch einen Hype-Charakter hat. Wie bei allen Hype-Themen ist es schwer, präzise und anerkannte Definitionen des Ge-biets und von dessen Kernbegriffen zu finden. Der Service ist das zentrale Konzept einer SOA. Aber was ist eigentlich ein Service? Dafür gi...

In this contribution we present its basic and advanced concepts plus a concrete set of rules for architectural design on enterprise level. By explicitly working out these concepts and rules we can get a lot more tangible on semantics of the hyped concept of service- oriented architecture (SOA).
