We're proud to announce the immediate availability of :BaseKB
Early Access 2
http://basekb.com/dl/earlyaccess.php
The EA2 release fixes a number of problems in EA1, most
particularly, problems that affected name resolution. EA2 also comes
with the initial release of basekb-tools:
http://code.google.com/p/basekb-tools/
an open-source package that implements the name resolution
behavior of the proprietary MQL query engine for SPARQL. Put simply,
basekb-tools takes a readable query like
select ?date {
graph public:baseKB {
basekb:en.united_states
basekb:location.dated_location.date_founded ?date .
}
}
and rewrites it it with identifiers that satisfy the unique name
assumption
select ?date {
graph public:baseKB {
basekb:m.09c7w0 basekb:m.035qyst ?date .
}
}
This grounding process is the key innovation that makes :BaseKB the
first correct RDFization of Freebase. :BaseKB covers the intersection
of Freebase and Wikipedia and, like the Freebase quad dump, is
available freely under a CC-BY license.
By installing :BaseKB in a triple store and using basekb-tools, you
can write queries against Freebase using the industry-standard SPARQL
1.1 language. basekb-tools contains a test suite that confirms the
correctness of of the knowledge base and compatibility with your
triple store. We believe that this kind of test suite is a practical
answer to pressing problems of Proof and Trust in the semantic web.
:BaseKB is an important milestone for both Freebase and the Semantic
Web, says Ontology2 founder Paul Houle, :BaseKB opens Freebase to
users of SPARQL and other RDF standards. The superior quality of
Freebase data solves data quality problems that have, so far,
frustrated Linked Data applications.
Ontology2 founder Paul Houle will be speaking at the SemTechBiz
converence in San Francisco on June 7. His talk, Linked Data, Free
Pictures, and Markets for Semantic Data will cover Ookaboo, :BaseKB
and how they fit into the rapidly emerging semantic-social ecosystem.

[Dbpedia-discussion] Geographic Coordinates of Places
Hello Everybody I have a couple of questions and probably you have the correct answer that I can't find. 1) I'm retrieving city points using the SPARQL endpoint and I find that there are various predicates for the geographic coordinates: geo:lat , geo:long, geo:POINT, grs:point and geo:geometry For my convenience I used geo:geometry WKT format, but I realized that not all the resources have this predicate (http://dbpedia.org/page/Oslo does not have it while http://dbpedia.org/page/Barcelona) has it. It poses me the question, Which of those predicates is present in all the resources? 2) This question comes from a problem that I have with some points in DBpedia. For example Allueva (Spain). Are the coordinates extracted from Wikipedia geodata or from another service? Because I see that the properties are properly parsed dbpedia:latd, dbpedia:latm, dbpedia:latns etc but the geo:geometry has a different value.

[Dbpedia-discussion] Data returned on dbpedia.org/ontology/
Hi group, We work on some software which heavily relies on the ontologies used by the data. This means we dereference the ontologies used on data sets and do some inference to figure out additional stuff about the data. For most ontologies this works pretty well. Last week we were test driving our software against some data at DBPedia, namely the page of Tim Berners-Lee at http://dbpedia.org/resource/Tim_Berners-Lee So far so good, in there we have several rdf:type definitions, including dbpedia-owl:Person, which points to http://dbpedia.org/ontology/Person On that point we noticed that it took way too long to get the page, cache it and do some stuff on it. So we started analyzing it and did it by hand: % curl -I -H Accept: application/rdf+xml http://dbpedia.org/ontology/Person HTTP/1.1 303 See Other Date: Mon, 21 May 2012 19:00:08 GMT Content-Type: application/rdf+xml Connection: keep-alive Server: Virtuoso/06.04.3132 (Linux) x86_64-generic-linux-glibc25-64 VDB Accept-Ranges: bytes Location: http://dbpedia.org/data3/Person.rdf Content-Length: 0 Not a problem, the system can handle redirects. So we get the other file instead. And boy were we confused: It returns an 8MB file for the request (which took quite some time to get btw) After analyzing it in rapper I figured out that we got about 50'000 triples, probably less than 20 are really related to the ontology and the rest is stuff like: http://dbpedia.org/resource/Zygmunt_Balicki a http://dbpedia.org/ontology/Person . While I do see that this reverse property or however it is called might be interesting when I browse the data set in my web browser it is in my opinion plain wrong to return it on the URI which dereferences the ontology. Our software is also targeted at smart phones, you can imagine that it is not really fun to get 50'000 triples back on a crappy 3G link with volume limits and then parse and cache them on a device which is running on battery power. If I do that on several dbpedia data sets I'm probably out of power very soon and didn't even get half of the ontologies used in the data. What is your opinion on that? Is there a good reason for this or did you just think it might be useful? As you can see this pretty much kills the way we use ontologies and I think the classical way to dereference ontologies makes way more sense, so I would vote to change this behavior on dbpedia and return uniquely the definition itself. thanks cu Adrian -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Re: [Dbpedia-discussion] decimal and grouping separators doubt
Hello everybody, I was having a look at DBpedia data about cities as for example the area total property. I would like to know how do you deal with different decimal separators and grouping separators between countries. For example I found that in http://pt.wikipedia.org/wiki/Rio_Rufino the area total is 282,569 km² and I think the , is a decimal separator according to the Brazilian convention [1] . However in the DBpedia dataset I found the following value: 2.82569E11. My guess is that separator is being used as grouping separator as it is the convention in United Kingdom [2] for example. I would be very thankful if you can enlighten me.

Re: [Dbpedia-discussion] Geographic Coordinates of Places
Thanks. Your answers and links helped a lot. But, It would be nice to review how DBpedia obtains the geo:lat,geo:lon and geo:geometry because there are resources with incoherent data (geo:lat has an apparently incorrect value while the dbpedia extractions from Wikipedia are correct). If those values come from the Wikipedia dumps seems like the geo-extractor is failing in some cases, obtaining incorrect geo:lat geo:lon values. Salut!

Re: [Dbpedia-discussion] Data returned on dbpedia.org/ontology/
Separation of schema and instances is a good solution for this symptom. The root of the problem seems to be that when the amount of data grows, just returning everything you know about something is not going to cut it. A solution for that seems to be still missing. Perhaps we need a mechanism of views for linked data -- building upon the notion of named graphs already implemented by SPARQL endpoints? So: http://dbpedia.org/ontology/Person?graph=schema Would return only T-Box statements. And: http://dbpedia.org/ontology/Person?graph=instances Would return only A-Box statements. Meanwhile: http://dbpedia.org/ontology/Person?graph=my-arbitrary-view Would return only statements that Pablo thinks are important. That being done, one could say that the default view would be ?graph=schema. This would perhaps address the issue more deeply? Cheers, Pablo PS: Of course, feel free to read http://dbpedia.org/ontology where I said schema; same goes for http://dbpedia/resource where I said instances. It's just an identifier.

If the number format is correct English, and the statics say that most numbers are xx format, the number could be converted to the local format by using a conversion function.

Hi Maria,
thanks for the report!
The problem is that the number is displayed with a comma as the
decimal separator, but in the source text of the page [1], the decimal
separator is a dot:
| área = 282.569
The template [2] that generates the HTML from the source expects the
number to use a dot and formats it appropriately for
Brazilian/Portuguese:
{{formatnum:{{{área}
To fix this problem, we will have to extend our extraction framework,
so that users can specify which decimal separator is used in the
values of a certain template property.
@developers: We will have to discuss what's the best way to do this...
- Add a configuration value decimalSeparator whose value may be dot or
comma: , or .. Bit hard to read... We would also need a
configuration value groupSeparator.
- Add a configuration value numberFormat that takes a language code,
in this case en.
- Add a configuration value numberFormat that takes a decimal

Hello everybody,
I was having a look at DBpedia data about cities as for example the
area
total property. I would like to know how do you deal with different
decimal
separators and grouping separators between countries. For example I found
that in http://pt.wikipedia.org/wiki/Rio_Rufino the area total is
282,569
km² and I think the , is a decimal separator according to the Brazilian
convention [1] . However in the DBpedia dataset I found the following
value:
2.82569E11. My guess is that separator is being used as grouping
separator
as it is the convention in United Kingdom [2] for example.
I would be very thankful if you can enlighten me.
Cheers,
María

It may seem like overkill, but there's almost certainly a good reason for it (although I don't know what it is).
