LOTUS: Linked open text unleashed

Abstract

It is dificult to find resources on the Semantic Web today, in particular if one wants to search for resources based on natural language keywords and across multiple datasets. In this paper, we present LOTUS: Linked Open Text UnleaShed, a full-text lookup index over a huge Linked Open Data collection. We detail LOTUS' approach, its implementation, its coverage, and demonstrate the ease with which it allows the LOD cloud to be queried in different domain-specific scenarios.
