Dear Sherman,
It's great to have more activity, and all strength to you.
However, I would like to ask if you could modify some of your
description to more accurately reflect what it is doing.
Referring to the dataset as the "public LOD cloud instance of
Virtuoso" suggests that it is browsing all the LOD data, which it
is not.
Thanks so much for your insightful point, it's very well taken.
I have added a link to the about page for the instance, which contains
data about the VoiD graph <http://lod.openlinksw.com/void/Dataset>
that lists the datasets currently browsable.
The VoiD graph is layered:
1. Top --- Graph Groups
2. Bottom -- Actual Named Graphs
You can scope SPARQL to items 1 or 2.
As for what in the instance:
1. RDF data set dumps (the one published to ESW Wiki and others)
2. Progressively crawled data that follows a number of sitemap.xml links
3. Progressively crawled data from PingTheSemanticWeb
I hope this clarifies matters.

Also, I am not sure it is right to call it a "linked data
browser"; I can't work out how to use it to browse any other sites
than the Virtuoso EC2 one.
Hmmm, I dunno, I think it's an accurate description, or at least the
best I could come up with. I believe if a browser allowed navigation
of only one triple (a subject linked to an object), it constitutes a
linked data browser.
Best,

PS Sorry to those who feel I have been here before, but I think
there are important things here.

Hi All,
Taking inspiration from Longwell[1] and Parallax[2], I present yet
another linked data browser[3]. 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].
Feedback appreciated.
Hints:
- Click a breadcrumb at the top to navigate your query path
- Click "Your query" to view the filter details, click the nodes
there to navigate the path, click the icons there to modify the filter
- Click the green plus sign button to add a filter
- Click the blue undo button to unbound a node value
Notes:
I was amazed in the many instances where I got better results from
LOD dataspace than from Google/Technorati/Wikipedia. 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
<http://www.google.com/search?q=Monopoly%20knockoffs> . Kingsley
tells me that Entity Rank [4] has to do with this, but I wonder
whether this quality will stick as the cloud increases.
