KIT releases 14 billion triples to the Linked Open Data cloud
We are happy to announce that the Institute AIFB at the KIT is releasing the biggest dataset until now to the Linked Open Data cloud. The Linked Open Numbers project offers billions of facts about natural numbers, all readily available as Linked Data. Our accompanying peer-reviewed paper [1] gives further details on the background and implementation. We have integrated with external data sources (linking DBpedia to all their 335 number entities) and also directly link to the best-known linked open data browsers from the page. You can visit the Linked Open Numbers project at: http://km.aifb.kit.edu/projects/numbers/ Or point your linked open data browser directly at: http://km.aifb.kit.edu/projects/numbers/n1 We are happy to have increased the amount of triples on the Web by more than 14 billion triples, roughly 87.5% of the size of linked data web before this release (see paper for details). We hope that the data set will find its serendipitous use. The data set and the publication mechanism was checked pedantically, and we expect no errors in the triples. If you do find some, please let us know. We intend to be compatible with all major linked open data publication standards. About the AIFB The Institute AIFB (Applied Informatics and Formal Description Methods) at KIT is one of the world-leading institutions in Semantic Web technology. Approximately 20 researchers of the knowledge management research group are establishing theoretical results and scalable implementations for the field, closely collaborating with the sister institute KSRI (Karlsruhe Service Research Institute), the start-up company ontoprise GmbH, and the Knowledge Management group at the FZI Research Center for Information Technologies. Particular emphasis is given to areas such as logical foundations, Semantic Web mining, ontology creation engineering and management, RDF data management, semantic web search, and the implementation of interfaces and tools. The institute is involved in many industry-university co-operations, both on a European and a national level, including a number of intelligent Web systems case studies.

With about 8000 employees and an annual budget of 700 million Euros, KIT is the largest technical research institution within Germany.

Re: KIT releases 14 billion triples to the Linked Open Data cloud
Hi Denny, I am sorry, but I have to voice some criticism of this project. Over the past two years, I have become increasingly wary of the excitement over large numbers of triples in the LOD community. Large numbers of triples don't mean don't necessarily mean that a dataset enables us to do anything novel or significantly useful. I think there should be a shift from focusing on quantity to focusing on quality and usefulness. Now the project you describe seems to be well-made, but it also exemplifies this problem to a degree that I have not seen before. You basically published a huge dataset of numbers, for the sake of producing a large number of triples. Your announcement mainly emphasis on how huge the dataset is, and the corresponding paper does the same. The paper gives a few application scenarios, I quote The added value of the paradigm shift initiated by our work cannot be underestimated. By endowing numbers with an own identity, the linked open data cloud will become treasure trove for a variety of disciplines. By using elaborate data mining techniques, groundbreaking insights about deep mathematical correspondences can be obtained. As an example, using our sample dataset, we were able to discover that there are signi cantly more odd primes than even ones, and even more excitingly a number contains 2 as a prime factor exactly if its successor does not. I am sorry, but this sounds a bit overenthusiastic. I see no paradigm shift, and I also don't see why your findings about prime numbers required you to publish the dataset as linked data. I also have troubles seeing the practical value of looking at the resource pages for each number with a linked data browser, but I am also not a mathematician. I am sorry for being a bit antagonistic, but we as a community should really try not to be seduced too easily by publishing ever-larger numbers of triples.

Re: KIT releases 14 billion triples to the Linked Open Data cloud
Hi Denny, Interesting project. Why didn't you publish 140 billion triples, by publishing 10 Billion numbers, or 1.4 Trillion or 14 Trillion or ...? Looks like you stopped at 1 Billion: http://km.aifb.kit.edu/projects/numbers/index.php?number=9 http://km.aifb.kit.edu/projects/numbers/index.php?number=10 I think if we go public with something like this we should stress the value for people instead of the sheer size.

I have my own rational number dataset which I assumed would be much bigger than yours. However I seem to able to link each of your entities to mine, so maybe they're the same. Surprising! Currently working on a irrational number dataset. This one must be bigger, but I'm rapidly running out of storage space and I'm barely past 0. Damian

Preview of the New GoodRelations Language Reference
Dear all: Over the last weeks, we have been working on a much improved documentation of the GoodRelations vocabulary for e-commerce [1]. Our main goal was to provide a more readable, more accessible official specification. Please find a preview here: http://www.heppnetz.de/ontologies/goodrelations/20100401/v1.html This will replace the current document at http://purl.org/goodrelations/v1.html shortly. Please note that the ontology itself did not change, we just updated the rendering and organization of the HTML document. Also, this is not meant to replace the GoodRelations Primer [2], which is a tutorial-style introduction to using GoodRelations, and the GoodRelations Cookbook [3], which contains recipes for common scenarios. Any feedback would be greatly appreciated! Thanks to Alex Stolz and Andreas Radinger for their hard work on that!

Re: KIT releases 14 billion triples to the Linked Open Data cloud
One fact there's no avoiding, the service works! Bravo Denny. Compelling paper, although more scenarios would be good. My cousin told me about a cow being stuck in the village post office this morning, and in both cases things seemed interesting, and potentially useful towards Web serendipity.

How to Reply To messages from an archive?
Suppose I wanted to reply to a message from the archive, e.g.: http://lists.w3.org/Archives/Public/public-lod/2009Dec/0145.html If I did not get that email, how can I do this? As workaround, I suppose I can copy and paste the message and make it look like a reply, and if I get the subject right it may go into the right thread. Thanks Michael

Brilliant! Someone has too much time on their hands. Though it is better than becoming a terrorist and more useful than playing solitaire or Farmville :-)) Michael
