Query results have traditionally been represented in tabular form. This is mainly because queries are dominantly used to operate on relational data. Also, visual appearance of these tabular representations make them easier to understand. In scientific data-intensive researches where data changes frequently, queries are ad-hoc, and selecting the right portion of the incoming data to answer the research […]


Everybody dealing with the Semantic Web repeatedly comes across the terms IRI, URI, URL and URN. Nevertheless, I frequently observe that there is some confusion about their exact meaning. And, of course, others noticed that as well (see e.g. [RFC3305] or search on Google). To be honest, I even was confused myself at the outset. […]


In einem aktuellen Forschungsprojekt untersuchen wir Möglichkeiten der automatisierten Visualisierung von wissenschaftlichen Daten anhand deren Eigenschaften. Diese gestatten später den Einsatz leistungsstarker visueller Analysemethoden für große Datenmengen, beispielsweise in wissenschaftlichen Anwendungen. Im Rahmen dieses Projektes suchen wir ab sofort eine studentische/wissenschaftliche Hilfskraft für bis zu 40 Stunden/Monat. Deine Aufgaben Unterstützung bei der Analyse von Beispieldaten […]

However, the algorithms, input datasets, benchmarks, raw result datasets, as well as scripts […]

Every year thousands of students take that opportunity and get supported by […]
