It is surprisingly difficult to find things on today's Web of Data. You need an IRI to start traversing the interconnected knowledge graph. But how do you find such a resource-denoting IRI? On the Web of Documents you can use a search engine. Unfortunately, there are currently no search engines for the Web of Data. This is where LOTUS kicks in.
LOTUS, or Linked Open Text UnleaShed, is a text-based entry point to a large subset of today's Linked Open Data (LOD) Cloud. It allows 2 billion unique Linked Data IRIs to be searched based on an index that
covers 4.3 billion literals. Advanced users can further customize the text-based retrieval in LOTUS to fit better a wealth of use cases. Try it out over at http://lodsearch.org.
