In this paper we introduce Word Bucket, a mobile app that applies gamification to the problem of learning a foreign second language (FSL). Word Bucket consumes and produces linguistic data through user interaction, which can be used to improve available datasets relying on the power of the crowd. We describe the problems around handling "live" linguistic data and how semantic technologies can help to face the problem of data integration and its consumption in this specific scenario. Source

Creating and optimizing content- and dialogue-based recommendation processes and their GUIs (graphical user interfaces) manually is expensive and slow. Changes in the environment may also be found too late or even be overlooked by humans. We show how to generate such processes and their GUIs semi-automatically by using knowledge derived from unstructured data such as customer feedback on products on the Web. Our approach covers the whole lifecycle from knowledge discovery through text mining techniques to the use of this knowledge for semi-automatic generation of recommendation processes and their user interfaces as well as their comparison in real-world use within the e-commerce domain through A/B-variant tests. These tests indicate that our approach can lead to competitive results in terms of click-out rate, while requiring much less manual effort. Copyright © 2013 ACM. Source

The capability to provide on-demand service access for SMEs can further reduce costs and allow companies to concentrate investments on their core businesses which in turn facilitates the overall competitive advantage. In the FP7 European Project COIN, a platform for supporting SMEs is developed which combines the flexibility of an execution environment for Semantic Web services with agent-based service compositions. This paper presents an approach to integrate an implementation of a Semantic Web service platform with an agent platform. One major benefit of the combination is that through this the potential of agent systems, most notably flexibility, can be tapped. An obstacle is the integration of dynamically discovered services which often cannot be used by agents because of interoperability problems (e.g. data heterogeneity). By delegating this task to a Semantically Enabled Service Oriented Architecture (SESA), the agent platform can concentrate on coordination tasks. Coordination tasks include executing predefined compositions of services but also automatic compositions of semantic services by applying AI planning techniques, in particular by transforming service descriptions into the Planning Domain Definition Language (PDDL). The integration approach is motivated and described in the context of a high-level scenario coming from the area of enterprise interoperability. © 2012 Springer-Verlag. Source

In the energy domain a transition process has begun aiming at the realization of smart grids, where many perspectives on smart grids and thus, different definitions, exist. However, one aspect is widely accepted, namely that ICT is needed to support future smart grids. IT approaches are used to deal with the upcoming data exchange among the different stakeholders. The traditional supply chain, from centralized generation to conventional consumption, has evolved into a multi-dimensional, highly dynamic and complex system. Many new stakeholders such as service providers and prosumers participate in smart grids. Also, automation becomes more and more important, especially novel communication standards like the OPC UA. In this contribution the application of the OPC UA as well as its extension by annotating meta-data to enable semantic web service communication is introduced. © 2011 IEEE. Source
