The Linked Open Data (LOD) cloud has grown to an enormous source for semantic data. Its distributed and decentralized approach is one reason for its success but also poses challenges. A main difficulty is to identify those data sources on the LOD cloud which provide the information a user is actually interested in. With LODatio, we have developed a prototype retrieval system to support users in finding the right data sources for a given schema-oriented information need. Beyond classical search system functions such as retrieval, ranking, result set size estimation and providing result snippets, LODatio provides sophisticated support for the users in refining and expanding their information need.
