Abstract

This paper discusses and demonstrates how to create an intelligent user interface (UI) on top of an external SPARQL endpoint, when only an open SPARQL API is available. As a case study, the Nobel Prizes & Laureates Linked Open Data (LOD) service provided by the Nobel Foundation and the Sampo-UI framework for faceted search, browsing, and data analyses are considered. To show how this can be done easily, the semantic portal Nobel Prize Sampo, available online and on GitHub, is described and the lessons learned are discussed.
