Public Spending as LOD: The Case of Greece

The PSGR project is the first attempt to generate, curate, interlink and distribute daily updated public spending data in LOD formats that can be useful to both expert (i.e. scientists and professionals) and naive users. The PSGR ontology is based on the UK payments ontology and reuses, among others, the W3C Registered Organization Vocabulary and the Core Business Vocabulary. RDFized data are linked to product classifications, Geonames and DBpedia resources. Online services contain advanced search features and domain level information (e.g. local government), simple and complex visualizations based on network analysis, linked information about payment entities and SPARQL endpoints. During February 2013, the growing dataset consists of approximately 2 mil. payment decisions valued 44.5 bil. euros forming 65 mil. triples.

Pervasiveness in Real-World Educational Games: A Case of Lego Mindstorms and M.I.T App Inventor

Without a doubt, children consider mobile phones to be something more than just a means of communication. It is, actually, an extension of themselves and an integral part of their lives. The unique relationship that they have developed with these devices, which has been reinforced with the launching of smartphones, could not be left unnoticed by the educational community as every successful educational activity does not exist without the motivation of students via a climate of enthusiasm and the constant providing of incentives. Games, digital or otherwise, at school fall under the same category. Their blending and the children’s response to them are particularly interesting and, thus have triggered off the creation of a game, presented within the context of this paper. This game, designed for smartphones with android O.S, was developed through the M.I.T. App Inventor programming environment, which interacts with Lego Mindstorms robotic constructions.
