Re: Yet Another LOD cloud browser

I have difficulty in interpreting what you say - we are looking at the same "linked data browser" page?:
All I can see is a page that says: "Lookup things named "" " So the only possibility of linked data browsing is to put in something with a name.
So I put something topical in (from this list).
Since I see
  <Station rdf:about="">
    <foaf:name xml:lang="en">Manchester Piccadilly</foaf:name>
I try "Manchester Piccadilly" and get some response, but nothing leads me to or any of the data I find there.
Similarly topical from this list, I find no way of browsing or getting to that page by searching for "Keith Alexander".

I also see no way of doing "3. Raw URI Lookup" of this URI.

I assert that if this is a "linked data browser", then since conforms (I think) to "How to Publish Linked Data on the Web", then I should be able to browse it using the browser.
If I can't, then it is not a "linked data browser".

Of course, this browser is very capable of browsing your excellent single site, but that is not the same thing, I am sorry to say.

Thank you for pointing out this is not in EC2.
I have difficulty working out what is in the cloud and what is not, as it appears to be opaque, which I think is the idea.

What do you mean by: I can't work out how to use it to browse any other
sites than the Virtuoso EC2 one? For starters, this isn't an EC2 hosted
instance. Its a huge Quad Store with 4.5 Billion+ (and counting)
triples. You find entities and their descriptions via:

1. Full Text Search Patterns
2. Entity URI Lookup by Label
3. Raw URI Lookup

There is a Tab for each.

When you find an entity and open up its description, you can click on
"Statistics" to explore other relationships and/or how we've handle
owl:sameAs, IFPs etc..

If the above, don't get you where you want to be, then you can also
start from the VoiD graph at:
And of course, if all fails, you can simply use the SPARQL endpoint at: .

If data is missing simply give me an example of a query that works in
your data space and we'll look into why its missing in ours.

It uses the Virtuoso Facets Web service API [4] and runs against the public LOD cloud instance of Virtuoso [5]. I believe such faceted search UIs could be a nice compromise between SPARQL and a full-blown Cypher-based NL user interface[6].

For example, searching Monopoly, then filtering to the umbel-sc:MentalSituations category gave me a nice (and in some cases humorous) list of Monopoly knock-offs. I tried finding such a list on the WWW with no luck <> . Kingsley tells me that Entity Rank [4] has to do with this, but I wonder whether this quality will stick as the cloud increases.
