Re: [Dbpedia-discussion] United Nations FAO geo-political ontology dbpedia (was: how to register a RDF into DBPedia)
Hi Soonho, What do you mean by register? I see 3 options: 1. Link the countries/concepts in this ontology to their dbpedia equivalents. 2. Add this data to the dbpedia data, and have it published on http://dbpedia.org - I guess this is not trivially possible. DBPedia is mainly from wikipedia, but including a few other sources. 3. Add this data to your own copy of dbpedia to query them together, this depends on your database :) I actually had a look at the FAO ontology a while back, and you already link to dbpedia: I.e. countries have properties like: codeDBPediaID rdf:datatype=http://www.w3.org/2001/XMLSchema#string;Turks_and_Caicos_Islands/codeDBPediaID This means that for option 1, you have already done the hard conceptual work (i.e. figuring out what countries match). However, you have published it in your own crazy way that noone else understands :) The link should be a resource (i.e. URI) not a literal (i.e. string). It could for instance be: owl:sameAs rdf:resource=http://dbpedia.org/resource/Turks_and_Caicos_Islands; / For option 2 - it may well be worth exploring adding the FAO country list somehow - it is quite an authorative source as to what constitutes a country (re: paul houle most justified complaint that dbpedia lists 3000 countries) Cheers, - Gunnar Do you mean link these On 27/07/10 16:53, Kim, Soonho (OEKM) wrote: Dear All; How are you?

[Dbpedia-discussion] Broken subject URIs for Yago- or DbPedia triples
I already posted this in a reply to another thread, but I actually don't think it's really the same problem as that one. Compare: http://dbpedia.org/page/The_Good_Shepherd_%28film%29 and http://dbpedia.org/page/The_Good_Shepherd_(film) The one without encoding has the yago:blah triples, the other the normal dbpedia stuff. This affects all URIs with ( ) in them, (perhaps also with : - see other thread) Surely this is broken? :) Cheers, - Gunnar -- Gunnar Aastrand Grimnes DFKI GmbH http://www.dfki.uni-kl.de/~grimnes -- ___ Dbpedia-discussion mailing list Dbpedia-discussion@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dbpedia-discussion
Re: [Dbpedia-discussion] 303 redirects oddity for URIs containing :
This also affects URLs with ( ), and there also seems to be a bug in the
actual triples.

As far as i remember colon is not valid in URI local part, right?

seems not to disallow colons in URI paths for HTTP at least:
path = path-abempty; begins with / or is empty
...
path-abempty = *( / segment )
...
segment = *pchar
...
pchar = unreserved / pct-encoded / sub-delims / : / @
I'm no expert on this matter though. DBpedia *does* use colons in URIs
anyways...
I did some quick testing with Firefox; it looks like there's no
URLDecoding/URLEncoding going on when following Location: headers in 303
redirects there, so Firefox behaves just like Java does.
Also interesting:
$ curl -v http://dbpedia.org/resource/X-Men:_Evolution
(just normal HTML!)
HTTP/1.1 303 See Other
Location: http://dbpedia.org/page/X-Men:_Evolution
No escaping going on here when doing the normal HTML request. So I guess
this is a bug in Virtuoso when requesting application/rdf+xml (and a
somewhat strange bug in curl perhaps).

Hi!
Apparently there's something odd with the 303 redirects for resources
with : in their title. Basically, that seems to work from for example
curl, but it fails from Java. I'm not sure what component is buggy there.
Example:
$ curl -v -H Accept: application/rdf+xml
http://dbpedia.org/resource/X-Men:_Evolution
...
HTTP/1.1 303 See Other
Content-Location: /data/X-Men%3A_Evolution.xml
$ curl -H Accept: application/rdf+xml
http://dbpedia.org/data/X-Men:_Evolution
...is fine.
$ curl -H Accept: application/rdf+xml
http://dbpedia.org/data/X-Men%3A_Evolution
...isn't - that strangely returns some foaf triples though (seems these
are returned for whatever data/ URI you request).
Java seems to get redirected to the latter (broken) URI:
url = http://dbpedia.org/resource/X-Men:_Evolution;;
URL urlU = new URL(url);
HttpURLConnection uc = (HttpURLConnection) urlU.openConnection();
uc.setInstanceFollowRedirects(true);
uc.setRequestProperty(Accept, application/rdf+xml);
uc.connect();
InputStream is = uc.getInputStream();
int read;
while ((read = is.read()) != -1) { System.out.write(read); }
...outputs the triples the last (broken) curl command also fetches.
Bug in Java? Bug in Virtuoso?
I found a related discussion at [1] but that didn't cover the : case.

Malte

[Dbpedia-discussion] CFP: Talis sponsored Semantic Sc ripting Challenge at SFSW09 - Win 250€, deadline 15th of May
(Apologies if you receive this more than once and this is the last time I promise! ) Talis has kindly agreed to sponsor this year's Semantic Web Scripting Challenge with a 250€ cash prize -- To celebrate we have also moved the deadline one month forward, now to 15th of May! http://www.semanticscripting.org/SFSW2009/challenge.htm The Semantic Web Scripting Challenge is a part of the 5h Semantic Web Scripting Workshop (SFSW09) at ESWC2009. It awards a prize to the most innovative small scripting application or mashup. (Prize details will be published shortly!) It is an annual event, last year's prize of 250€ was won by Benjamin Nowack for SPARQLBot - the Semantic Web Commandline. The application must be implemented using a scripting language and Semantic Web technologies. It should access, visualize or combine information from more than one source in novel or unforeseen ways. For the purpose of the Challenge we define a small application as being less than 1000 lines of code (excluding external libraries), and focusing on one specific problem or application. The challenge is open to anyone interested in developing applications, services, or infrastructure for the Semantic Web, using Scripting Languages. This might include students, developers, researchers, and people from industry. Individual or group submissions are both acceptable. Criteria: - Entries will be assessed according to the extent to which they: * Demonstrate innovation through the use of Scripting Languages * Highlight the technical capabilities of a Semantic Web * Bring benefits to potential users All three criteria will be given equal importance in selecting the winning entry. In the event of a tie, the entry deemed to bring greatest benefits to potential users will be awarded the prize. Reviews and Judging: Submissions to the Scripting Challenge will be reviewed by members of the Programme Committee of the 5th Workshop on Scripting for the Semantic Web. A final decision will be made by the Organising Committee of the workshop, based on the reviews by Programme Committee members. Submissions: Submissions should consist of a 2 page description (in Springer LNCS format) of the application, ideally accompanied by the source code and a link to an online demo. Descriptions and accommpanying materials should be submitted electronically via the workshop management system by May 15th, 2009. Descriptions of the submissions will be included in the workshop proceedings. Entries to the Scripting Challenge may be presented at the workshop by their authors, however authors of Scripting Challenge submissions are not required to attend the workshop personally. Submissions to the Scripting Challenge may include work that has previously been published elsewhere. However in this case we would expect entries to demonstrate novelty through new features, or deployments of the application with new data sets. Scripting Challenge Submissions are submitted by email to: gunnar.grimnes (AT) DFKI.de Please include SFSW09 Scripting Challenge in the subject. In the event of any queries regarding the Scripting Challenge, please see: http://www.semanticscripting.org/SFSW2009/challenge.htm or contact Gunnar Aastrand Grimnes.
