WETICE '14: Proceedings of the 2014 IEEE 23rd International WETICE Conference
Publisher: IEEE Computer Society
Large-scale temporal graphs can serve as a model in many application scenarios. Recently, due to the popularity of online social networks and increased research interest in reality mining i.e. gathering and analyzing data about human behavior and interaction in the real world, temporal graphs gain traction in social network analysis ...

This paper highlights how the domain of Smart Cities is often modeled by ontologies to create applications and services that are highly flexible, (re)configurable, and inter-operable. However, ontology repositories and their accompanying reasoning and rule languages face the disadvantage of bad runtime behavior, especially if the models grow large in ...

WETICE '13: Proceedings of the 2013 Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises
Publisher: IEEE Computer Society
We present an approach to data mining on arbitrary graph data that uses a cloud-based distributed computing model for dynamic provisioning of computing resources as the graph model grows or shrinks. Further, we introduce the concept of logging graph changes as a basis for calculating properties of dynamic graphs. We ...

In collaborative software development, the utilization of Version Control Systems VCSs is a must. For this, a multitude of pessimistic as well as optimistic VCSs for model artifacts emerged. Pessimistic approaches follow the lock-edit-unlock paradigm whereas optimistic approaches allow parallel editing of one resource, which are therefore the preferred ones. ...
