ANN: Linked Data/Semantic Web Application - RKBExplorer

[Hugh Glaser]

Dear Colleague,

We have revamped a lot of the RKB and RKBExplorer infrastructure since last
exposing it here, so you may well like to give it another visit at
http://www.rkbexplorer.com/

There you will find a user interface to a world of Linked Data, although it
is specifically designed to avoid exposing users to any Linked Data or
Semantic Web technologies directly. We hope it looks like a "normal" Web 1.0
or 2.0 site.

The RKBExplorer gives consolidated views on a core set of Linked Data sites
(listed at http://www.rkbexplorer.com/data and comprising about 100M triples
at 40 domains), plus the many external Linked Data sites and resolvable URIs
for which it then finds references, notably dbpedia.org. This external
knowledge is discovered by dynamic browsing as well as dynamic co-reference
analysis, and the knowledge base for this co-reference (exposed at
http://sameas.org/) currently has over 6M different entities from 20M URIs.

The user domain is of workers looking to explore many aspects of researchers
and research topics, although the emphasis is currently around Computer
Science, and especially Resilient Systems.

The underlying infrastructure for all this is very open, with RESTful
interactions, and so available to anyone; however the purpose of this email
is to draw attention to the RKBExplorer as a (hopefully) useful application,
and a possible system that you might choose to use to demonstrate the power
of Linked Data and the Semantic Web to others. Feel free to pass on the URI.
Feel free to contact me if you think you might like to use a service.

Best

HG: We have revamped a lot of the RKB and RKBExplorer infrastructure since

Visited and found some ontology tendered as a reference ontology,
http://www.aktors.org/ontology/. Here are the top lines:
"A very simple top-level. We define something called THING, which is the
top-level concept in the ontology.  We then distinguish two basic
types of 'things': TANGIBLE-THING, something that has some physicality, and
INTANGIBLE-THING, something which has not. We use a very open definition
of being tangible: obviusly a physical object is tangible, but also a
sub-atomic particle is tangible, even if some of them are very tricky (you
do not see them)
you only see the trace they leave behind.  Also a piece of software will be
considered a tangible thing, it is something that you can see on a floppy
disk.
In contrast an algorithm will be an intangible, although the file that
contains its implementation will be a tangible thing."
Something more in this line: Intangible Thing is not tangible...Tangible
Thing, something which is not intangible... Quantity is of two subclasses:
Number and Physical Quantity, etc.
Wonder is it an experimental trial or completed work? Thanks.

The ontology is not part of our project.
It was developed in the AKT Project, which ended a couple of years ago.
I would say there is no maintenance activity on the AKT ontologies.
We just use it as one of the ones we use, partially because there was
existing data defined - we just take it as read; I guess it is legacy.

By "it" I assume you mean the RKB and RKBExplorer.
It is neither - it is intended to be a tool for practical use, and is the
subject of continuing improvement, we hope.

Thank you for your interest.

Hugh
is fantastic to see 'the sw' in my usual browser , brilliant work

especially the faceted browsing

thoughts:
 and some aspect of the navigation and visualization could be improved.

clicked on some resources and found lots of info, but could not get to the resource , (systems keeps on opening windows of information but never opens the document) would be nice to have a way maybe color code/flag  to distinguish information about the resource from the resource itself, for those who are in a hurry to find the doc

Some of the nomenclature may benefit from some translation
'
resolvabe uri (uh? maybe add plain language on mouseover)

You can also view the global equivalence closure across all repositories.  (what?)

etc

properly labelled, it wold be a good opportunity to learn
about these terms

will contact you offlist for more thoughts

cheers
