abstract = {The automotive industry faces three major challenges – shortage of fossil
fuels, politics of global warming and rising competition. In order to remain
competitive companies have to develop more efficient and alternative fuel
vehicles. Out of these challenges new cooperation models become inevitable. The
development of complex products like automobiles claims skills of various
disciplines e.g. engineering, IT. Furthermore, these skills are spread all over
various companies within the supply chain and beyond. Hence, supporting IT
systems for collaborative, innovative work is absolutely essential.
Interdisciplinary and interorganizational development has new demands on
information systems. These demands are not well analyzed at the moment and
therefore, existing collaboration platforms cannot address them. In order to
determine these new requirements and show the gap to existing collaboration
platform we performed a case study. In this case study, we analyze the research
campus “Active Research Environment for the Next Generation of Automobiles”
(ARENA2036). It is a is a new cooperation form, where diverse partners from the
industry, research institutes and universities elaborate collaboratively future
topics in the field of production and light weight construction under “one
single roof”. We focus on the special needs of the interdisciplinary,
interorganizational partners. The requirements were polled by a questionnaire.
About 80 percent of the active research workers in ARENA2036 answered the
questionnaire. By the answers we can identify the special needs and also role
profiles of the collaborators. The resulting role profiles specify the personal
requirements. These are used for an evaluation of existing information
platforms. The deficits between the offered features and the demands of the
partners, as well as new technologies supporting the individual needs of users
are the foundation for the information system concept for ARENA2036. In our
findings we present a role-based view on requirements for the development of an
information system for collaboration and cooperation. Based on these
requirements we then develop a concept for mobile apps with focus on a
role-based design.},

to speed up their business and to lower costs. Due to emerging technologies in
the field of Internet of Things, changing situations can be recognized
automatically, which provides the basis for an automated adaptation of process
executions in order to react to changing circumstances. Although approaches
exist that enable creating self-adapting workflows, a systematic modelling
approach that supports the specification of situational dependencies directly
in workflow models is missing. In this paper, we tackle this issue by
presenting a modelling extension called SitME that defines (i) an extensible
Situation Event type, (ii) the concept of Situational Scopes, and (iii) a
visual notation. As the introduced extension is language-independent, we apply
the approach to BPEL to validate its practical feasibility.},

abstract = {Efficient application provisioning is one of the most important issues in Cloud
Computing today. For that purpose, various provisioning automation technologies
have been developed that can be generally categorized into two different
flavors: (i) declarative approaches are based on describing the desired goals
whereas (ii) imperative approaches are used to describe explicit sequences of
low-level tasks. Since modern Cloud-based business applications become more and
more complex, employ a plethora of heterogeneous components and services that
must be wired, and require complex configurations, the two kinds of
technologies have to be integrated to model the provisioning of such
applications. In this paper, we present a process modelling concept that
enables the seamless integration of imperative and declarative provisioning
models and their technologies while preserving the strengths of both flavors.
We validate the technical feasibility of the approach by applying the concept
to the workflow language BPEL and evaluate its features by several criteria.},

abstract = {Today, a multitude of highly-connected applications and information systems
hold, consume and produce huge amounts of heterogeneous data. The overall
amount of data is even expected to dramatically increase in the future. In
order to conduct, e.g., data analysis, visualizations or other value-adding
scenarios, it is necessary to integrate specific, relevant parts of data into a
common source. Due to oftentimes changing environments and dynamic requests,
this integration has to support ad-hoc and flexible data processing
capabilities. Furthermore, an iterative and explorative trial-and-error
integration based on different data sources has to be possible. To cope with
these requirements, several data mashup platforms have been developed in the
past. However, existing solutions are mostly non-extensible, monolithic systems
or applications with many limitations regarding the mentioned requirements. In
this paper, we introduce an approach that copes with these issues (i) by the
introduction of patterns to enable decoupling from implementation details, (ii)
by a cloud-ready approach to enable availability and scalability, and (iii) by
a high degree of flexibility and extensibility that enables the integration of
heterogeneous data as well as dynamic (un-)tethering of data sources. We
evaluate our approach using runtime measurements of our prototypical
implementation.},

research project ECHO is to support the treatment of patients, who suffer from

Usually the patients need to be examined by their physicians on a regular basis

expensive, we develop an eHealth system which allows the physician to monitor
patients conditions remotely, e.g., via smart phones. Therefore, a secure data

and robust manner. However, the dynamic nature of modern information systems,
the upcoming Industry 4.0, and the Internet of Things increase the complexity
of modeling robust workflows significantly as various kinds of situations, such
as the failure of a production system, have to be considered explicitly.
Consequently, modeling workflows in a situation-aware manner is a complex
challenge that quickly results in big unmanageable workflow models. To overcome
these issues, we present an approach that allows workflows to become
situation-aware to automatically adapt their behavior according to the
situation they are in. The approach is based on aggregated context information,
which has been an important research topic in the last decade to capture
information about an environment. We introduce a system that derives high-level
situations from lower-level context and sensor information. A situation can be
used by different situation-aware workflows to adapt to the current situation
in their execution environment. SitOPT enables the detection of situations
using different situation-recognition systems, exchange of information about
detected situations, optimization of the situation recognition, and runtime
adaption and optimization of situationaware workflows based on the recognized
situations.},

abstract = {Nowadays, mobile devices collect a lot of private information. Therefore every
vendor of a mobile platform has to provide a sufficient mechanism to secure
this data. Android pursues a strategy to pass full control (and thus full
responsibility) over any private data to the user. However, the Android
Permission System is not sufficient for that purpose. Various third party
approaches try to enhance the Android privacy policy model. Nevertheless, these
approaches have to solve the problem of how to deal with Legacy Apps, i.e.,
apps that do not collaborate with an enhanced privacy policy model.
In this paper, we analyze various alternative privacy systems and discuss
different approaches of how to deal with Legacy Apps. Based on our findings, we
introduce the so-called PMP Gatekeeper, a best of breed approach dealing with
Legacy Apps for the Privacy Management Platform (PMP). The PMP Gatekeeper
classifies apps and deals with each class appropriately. So the user can adjust
privacy settings for every kind of app. With our prototype we show, that the
PMP in combination with the PMP Gatekeeper becomes a holistic privacy system.
Although our prototype is for Android, our realization approach can be applied
to other application platforms in order to offer a satisfying privacy system.},

die Wissensvermittlung. Spezielle eLearning-Tools dienen dazu, Lernressourcen,

welchen Nutzen die computergest{\"u}tzte Umsetzung von Lernstands{\"u}berpr{\"u}fungen
(Tests und Klausuren) f{\"u}r Dozenten und Lernende haben kann. Stark assoziiert
mit Tests im eLearning-Bereich sind Multiple-Choice-Aufgaben. Als automatisch
korrigierbare Fragen k{\"o}nnen sie im eLearning-Umfeld schnell und objektiv
bewertet werden und liefern auch bei gro{\ss}en Teilnehmerzahlen schnell Feedback
an Lernende und Dozenten. Gleichzeitig zweifeln viele Dozenten daran, dass
diese Frageform die geforderten Kenntnisse und F{\"a}higkeiten wirklich
wiederspiegeln und bef{\"u}rchten ungerechtfertigte Erfolge durch Raten.
Freitextfragen umgehen diese Probleme und bieten den Mehrwert einer klareren
Einsicht in die Denkweise des Pr{\"u}flings, doch ist ihre Korrektur zeitaufw{\"a}ndig
und oft subjektiv. Wir geben Hinweise f{\"u}r die Praxis, die die Bewertung von
Freitextaufgaben verbessern und beschleunigen helfen, und illustrieren unsere
{\"U}berlegungen an einem realen Datensatz von Freitextfragen und Antworten, der im
Verlauf einer Einf{\"u}hrungsveranstaltung in die Programmierung f{\"u}r Informatiker

noch andauernde Arbeit an einem System zur halbautomatischen
Bewerterunterst{\"u}tzung vor, das vom computerbasierten Umfeld im
eLearning-Bereich profitiert und sowohl den Zeitaufwand f{\"u}r die manuelle
Bewertung als auch die Replizierbarkeit der Bewertungen weiter optimieren soll.},

abstract = {The automation of application provisioning and management is one of the most
important issues in Cloud Computing. However, the steadily increasing number of
different services and software components employed in composite Cloud
applications leads to a high risk of unintended side effects when different
technologies work together that bring their own proprietary management APIs.
Due to unknown dependencies and the increasing diversity and heterogeneity of
employed technologies, even small management tasks on a single component may
compromise the whole application functionality for reasons that are neither
expected nor obvious to non-experts. In this paper, we tackle these issues by
introducing a method that enables detecting and correcting unintended effects
of provisioning and management tasks in advance by analyzing the context in
which the tasks are executed. We validate the method practically and show how
context-aware expert management knowledge can be applied fully automatically to
provision and manage running Cloud applications.},
