In this paper, we describe the keyword-based semantic search engine KOIOS++ which interprets the keywords and computes a set of SPARQL queries. The special feature of KOIOS++ is that it leverages not only the class hierarchy but also the property hierarchy. The algo- rithm and data structures of KOIOS++ are based on a well-established approach that we extended by minor adjustments of the data structures and a sophisticated weighting strategy.
