Semantic Web Search Engine
Search for entities like "bill clinton", "radiohead", "stephen fry", "galway", "mus musculus", "amantadine", "muppets", or whatever else floats your boat.
Beta. Indexing a crawl of 1 billion facts (May 2010) + 1 billion inferred facts.
Running on one machine without result size cut-off. May be a bit slow for larger queries. Looks best in FireFox.
