abstract     = {In cultural heritage, large virtual collections are coming into 
existence. Such collections contain heterogeneous
 sets of metadata and 
vocabulary concepts, originating from multiple sources. In the context 
of the E-Culture demonstrator
 we have shown earlier that such virtual 
collections can be effectively explored with keyword search and semantic 
clustering.
 In this paper we describe the design rationale of ClioPatria, 
an open-source system which provides APIs for scalable semantic
 graph 
search. The use of ClioPatria’s search strategies is illustrated with a 
realistic use case: searching for ”Picasso”.
 We discuss details of scalable 
graph search, the required OWL reasoning functionalities and show why 
SPARQL queries
 are insufficient for solving the search problem.
