Hi Axel & all -

One can also approach RDF from an end-user perspective, as in

Re: An interactive shell for teaching RDF

[Sebastian Tramp]

quote Mischa Tuffield (24.7.2010):

Hello Axel,

- OntoWiki [1] has a similar interactive query shell with SPARQL syntax 
highlightning, save queries and other features.


- The SparqlTrainer [2] is an e-learning tool to practice SPARQL 
interactively.

I make sure of this sparql query command line shell. It resembles the 
mysql shell, and you can point it at arbitrary sparql endpoints.

Very useful for development, testing sparql endpoints.

An interactive shell for teaching RDF

[Axel Rauschmayer]

I wanted a hands-on session for my lecture on RDF, so I added an interactive 
shell to Hyena:
http://2ality.blogspot.com/2010/07/teaching-rdf.html

I'd be interested to know what others use to teach RDF (in a tutorial style).

RE: FOAF DL

[Michael Schneider]

Hi!

One note of caution!

The FOAF-DL ontology is only (approximately) equivalent to the original
version of FOAF in OWL /2/, since OWL keys have only been introduced as of
OWL 2. Older existing systems that depend on the FOAF inverse-functional
data properties (IFDPs) have to make sure that they can also work with the
new OWL 2 keys, before switching to the FOAF-DL ontology. 

If such a system internally uses a reasoner that is able to work with IFDPs
but does not know about OWL 2 keys (e.g. the current version of the Jena
rule reasoner), then the system will not be able to make the expected
inferences anymore, i.e. that two foaf:Person having the same mbox_sha1sum
are the same person. So one will have to decide to either stay with the old
FOAF ontology, or to replace the currently used reasoner.
 
This is, of course, a general problem when trying to upgrade to a newer
specification. But it should at least be stated explicitly, when publishing
a variant of an ontology that is in wide use.

CFP: Semantic Web Applications and Tools Workshop (SWAT4LS 2010)

[Adrian Paschke]

 

3rd Int. Semantic Web Applications and Tools

for Life Sciences


Berlin, 10th December 2010


  http://www.swat4ls.org/2010/


Overview


SWAT4LS is a workshop that provides a venue to present and discuss benefits
and limits of the adoption of Web based information systems and semantic
technologies in life sciences, biomedical informatics and computational
biology.

 

  _  


Rationale


The web is a key medium for information publishing, and web based
information systems play a key role in biomedical information exchange and
integration. At the same time, the variety and complexity of biomedical
information call for the adoption of semantic-based solutions. The Semantic
Web provides a set of technologies and standards that are key to support
semantic markup, ontology development, distributed information resources and
collaborative social environments. Altogether the adoption of the web-based
semantic-enabled technologies in the Life Sciences has potential impact on
the future of publishing, biological research and medicine. This workshop
will provide a venue to present and discuss benefits and limits of the
adoption of these technologies and tools in biomedical informatics and
computational biology. It will showcase experiences, information resources,
tools development and applications. It will bring together researchers, both
developers and users, from the various fields of Biology, Bioinformatics and
Computer Science, to discuss goals, current limits and some real use cases
for Semantic Web technologies in Life Sciences. 

  _  


Topics


Topics of interest include, but are not limited to: 

*   Standards, Technologies, Tools for the Semantic Web

*   Semantic Web standards and new proposals (RDF, OWL, SKOS, Linked
Data, . )
*   Biomedical Ontologies and related tools
*   Alternative approaches to integrate semantic representations and web
based solutions
*   Formal approaches to large biomedical knowledge bases

*   Systems for a Semantic Web for Bioinformatics

*   RDF stores, Reasoners, query and visualization systems for life
sciences
*   Semantic biomedical Web Services
*   Semantics aware Biological Data Integration Systems

*   Existing and prospective applications of the Semantic Web for
Bioinformatics

*   Semantics aware application tools
*   Semantic Wikis
*   Semantic collaborative research environments
*   Case studies, use cases, and scenarios

  _  


Type of contributions


The following possible contributions are sought: 

*   Research papers
*   Position papers
*   Posters
*   Software demos

We are also accepting proposals for tutorials, hackathons or other related
events to be held on Dec 8th (hackathons) and Dec 9th (tutorials). If
interested, please contact   info at swat4ls.org 

 

  _  


Proceedings


All accepted communications will be published in the proceedings.
Proceedings for the last editions of the workshop have been pubslished via
the CEUR-WS.org Workshop Proceedings service (see  
http://ceur-ws.org/). Best papers will be invited to a journal special issue
(probably BMC Bioinformatics).

  _  


Special issue


Authors of accepted contributions to the last editions of SWAT4LS have been
invited to submit extended and revised contributions for a special issue in
BMC Bioinformatics (dedicated to the SWAT4LS 2008 edition), and for a
special issue of the BMC Journal of Biomedical Semantics (dedicated to the
SWAT4LS 2009 edition, in preparation). We will continue with this approach
and we will announce more detailed infomation as soon as we have reached an
agreement with publishers. 

  _  


Deadlines


*   Submission openinig: 7 September 2010
*   Papers submission deadline: 12 October 2010
*   Posters and demo submission deadline: 1 November 2010
*   Communication of acceptance: 8 November 2010
*   Camera ready: 21 November 2010

  _  


Instructions


All papers and posters must be in English, formatted according to LNCS
format ( 
http://www.springer.de/comp/lncs/authors.html) and submitted in pdf format. 

*   Submissions for papers should report original research, and should
be between 8 and 15 pages.
*   Submissions for position papers should report qualified opinions,
recommendations or conclusions, and should be between 3 and 6 pages.
*   Submissions for posters should be between 2 and 4 pages.
*   Submissions for software demo proposals should also be between 2 and
4 pages.

  _  


Submission


All submissions will be handled via the EasyChair submission system. A link
will be provided when registrations open.
To ensure high quality, submitted papers will be carefully peer-reviewed by
at least three members of the Scientific Program Committee.

Re: Metaweb joins Google

[Danny Ayers]

It's not hard to find reasons to be cynical about Google's move,
mostly around the potential for them to make Freebase their own in the
sense of hiding it within their infrastructure and only exposing
proprietary, user-oriented interfaces - the temptation for Google to
"improve" aspects of the system, moving them away from standards.

There's certainly some coincidence between Google's aim of being the
one true search engine, and Freebase as *the* knowledge base.

But Metaweb were relatively quick to expose standards-based
interfaces, and their adoption of a CC license for the data has to be
commended. Another thing they got right was in picking up on the ways
people were spontaneously (well, not W3C-led anyway) using data on the
Web - wikis, tagging, folksonomies etc. (You could maybe say Metaweb
had similar aims at the core, but when it came to end-users pretty
much the opposite end of the spectrum from Cyc).

I agree totally with what Aldo and others have said about this being
great for getting the notion of graph out there, the right companies
do now seem to be getting on the bandwagon.

So worst case scenario I'd say would be for Google to play with the
tech, make things more proprietary, not get interesting results and
for the whole thing to wither as a failed experiment.

Best case maybe we see Google rapidly become a huge blob near the
centre of the linked data cloud, and additionally (and probably more
significantly) demonstrate one way the Web of Data can be useful by
enhancing their search engine.

Personally I'm optimistic, and congratulations to both Metaweb and
Google. Should be interesting...

Cheers,
Danny.
