Integrating Open Sources and Relational Data with SPARQL
We believe that the possibility to use SPARQL as a front end to heterogeneous data without significant cost in performance or expressive power is key to RDF taking its rightful place as the lingua franca of data integration. To this effect, we demonstrate how RDF and SPARQL can tackle a mix of standard relational workload and data mining in public data sources. We discuss extending SPARQL for b...
متن کاملVisualising Multiple Data Sources in an Independent Open Learner Model
This paper introduces the Next-TELL independent open learner model which is constructed based on data from a range of sources. An example is presented for a university course, with the learner model built from the main activities undertaken during the course. Use of the Next-TELL open learner model over a five week period is described for this group of students, suggesting that independent open...
متن کاملTowards Dataset Dynamics: Change Frequency of Linked Open Data Sources
Datasets in the LOD cloud are far from being static in their nature and how they are exposed. As resources are added and new links are set, applications consuming the data should be able to deal with these changes. In this paper we investigate how LOD datasets change and what sensible measures there are to accommodate dataset dynamics. We compare our findings with traditional, document-centric ...
متن کاملOnline Index Extraction from Linked Open Data Sources
The production of machine-readable data in the form of RDF datasets belonging to the Linked Open Data (LOD) Cloud is growing very fast. However, selecting relevant knowledge sources from the Cloud, assessing the quality and extracting synthetical information from a LOD source are all tasks that require a strong human effort. This paper proposes an approach for the automatic extraction of the mo...
متن کاملGalaxy: A Platform for Explorative Analysis of Open Data Sources
A large volume of Open Data is being generated on a continuous basis. Examples of this are the case of social, natural, and information systems such as World Wide Web and social networks. Most entities and objects in the Open Data are interconnected, forming a complex, semi-structured, and information-rich networks. In this sense, Linked Open Data has the potential to be similar to a federated ...
