MOCCAA - MObile Cloud Computing AdaptAble
(2019-08)
The primary objective of Mobile Cloud Computing (MCC) is the support of resource-constrained mobile devices by means of Cloud or nearby computing resources. In general, this is achieved by outsourcing or offloading computational intensive tasks of mobile applications. This allows, for instance, to virtually extend the processing power of mobile devices and, indirectly, to save battery life. In case remote resources are not available or the communication link is broken, still a local execution is possible.

Towards A Taxonomy of Text Mining Features
(Association for Information Systems, 2019)
Recently, text mining has received special attention from both researchers and practitioners, since it enables the development of intelligent and automated services. Text mining has been influenced by different disciplines like computer science, statistics, computational linguistics and library and information sciences. However, text mining features that evolved in one particular discipline are often unknown or rarely used in the other disciplines. No scientific feature framework exits which facilitates costly feature ...

Das NetworkParser-Framework
(2019-03-10)
Meine Dissertation, die im Fachbereich Elektrotechnik/Informatik in Kassel eingereicht wurde, hat das Ziel ein Tool zur Verfügung zu stellen, um den Entwickler bei der Entwicklung eines Programms in jedem Entwicklungsschritt zu unterstützen. Der komplette Ablauf von Story Driven Modeling wird dabei unterstützt. Das Tool soll so intuitiv bedienbar sein, dass Programmieranfänger damit arbeiten können und die Techniken erlernen können. Es ist gelungen ein kompaktes Tool für den kompletten SDM-Prozess zu schaffen, welches ...

Not All Reviews are Equal - a Literature Review on Online Review Helpfulness
(Association for Information Systems, 2019)
The amount of online reviews is growing significantly. Between 2014 and 2017, the number of reviews for TripAdvisor grew by 300% and for Yelp by 208%. However, not all online reviews are equally valuable. Some reviews are perceived to be more helpful or trustworthy then others. Hence, plethora of scholars have investigated the role of online reviews and researched factors and characteristics determining its helpfulness. Nevertheless, mixed findings were found. Consequently, the purpose of our paper is to present a ...

Buffered Simulation for Büchi Automata
(2019)
Wir stellen eine neue Familie von Simulationsrelationen zwischen zwei nicht deterministischen Büchi Automaten (NBA), genannt gepufferte Simulation vor. Wir erweitern das Spiel-Framework der üblichen fairen Simulation, so dass Duplicator ihren Spielzug überspringen und die Buchstaben, die Spoiler gelesenen hat, vorübergehend in einem Puffer speichern kann. Duplicator kann diese Buchstaben in ihrer Struktur dann später ausführen. Duplicator hat damit eine Vorschau in die Bewegungen von Spoiler und somit mehr Chancen, ...

Hybrid Branching-Time Logics
(2019)
We introduce and study an extension of the well-known and well-studied branching-time logics CTL, CTL+, FCTL+, CTL* and the modal μ-calculus with the so called "hybrid framework". This framework borrows ideas from first-order logic to enable more precise "structural" reasoning which is known to be impossible in the original logics. In particular, the extension with this framework enables these logics to uniquely name, reference and test for certain states, similarly to the concepts of variables and constants in ...

Towards Effective Natural Language Application Development
(2019)
There is a current trend that more and more computer programs analyze written or spoken natural language. For example, DVAs, IE systems, machine translation systems, and many other types of programs process natural language in order to solve specific use cases when interacting with humans via natural language. Amazon, Google, and Mycroft AI are just some of the companies that have produced DVAs capable of interacting with humans via voice. Such NLP applications use techniques from computer science and artificial ...
