You want to lookup a an Entity URI from the LOD Cloud, right?

Do explore the service at: http://lod.openlinksw.com ? Take note of the 
3 tabs on the home page.

Also note the VoiD graph at: http://lod.openlinksw.com/void/Dataset, 
meaning you can even start exploring the LOD cloud from the description 
of a dataset.

No you don't.  Take a look at  "URI Lookup (by Label)" tab.  Type in a 
literal pattern associated with an Entity who's URI you seek.

See comment above.

Yes, I am assuming Orri Erling made this crystal clear during his 
workshop talk. Otherwise, do try catching up with him if you can.
