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.
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.

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.


- 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


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.
