Sherman,
Good to see more faceted browsing work on LOD!
Will you be considering showing actual data or is showing the schema
your end goal? For example, I typed in "Microsoft", and I couldn't
seem to get any information about Microsoft. I only saw that there are
some other things related to Microsoft, e.g., people, but I couldn't
see what those things are (e.g., specifically, such as Bill Gates).
I'd like to show you what I mean but I can't seem to get a permanent
link to the state of the app.

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.

David,
Sherman's razrobase browser is using the REST API provided by the
Virtuoso instance at: <http://lod.openlinksw.com>, all you have to do
re. "Microsoft" is go there and type in pattern: Microsoft .
Once you do that, you will see an initial Entity Ranked page of
associated Entity URIs, text excerpts from literal values plus bars
intidicating Entity Rank and Text pattern match frequencies that drive
the ordering. At this stage, assuming you don't already see the Entity
URI for "Microsoft) you can pivot on: Type (razorbase:Category) or
Poperties (razorbase:Information) to narrow the focus of your quest.
The difference right now is that Sherman hasn't implemented the critical
"retry" and "timeout" functionality that lie at the core of this
system, once this is implemented our basic UI and his should produce
similar results with the only variance that our UI resides inside
Virtuoso while Razorbase is making RESTful calls from the outside :-)
I hope this clarifies things.
