Unfortunately I don't maintain one anymore. So I think the only thing that you will be able to do is to download their RDF dump, and to index it in some triple stores by yourself :| Thanks! Take care, Fred Hi Rohana!

I am investigating YAGO ontology these days and was wondering the possibility of accessing YAGO via SPARQL queries. What I am trying to do is to find resources that correspond to the entities (like Names, Companies) thatappear in webpages and markup them with RDFa as resources to enable finding more information about them. Do you or anyone know of any public SPARQL endpoints to YAGO ontology? If there is, that will help me minimise the overhead of having to maintain a server to provide the SPARQL endpoint. Regards Rohana Hi Frederick,

Thanks a lot for reporting this! First time I notice that, and really, it seems a crappy spamming bot that is exploiting some Wordpress bug. Seems that Wordpress are aware of the issue, but is not fixed so far (Wordpress 2.1 to 2.3.1 seems affected by the bug). I installed something that will notice me if this happen again, so that I delete it. Will monitor this, thanks! Take care, Fred Hi Thomas!

I agree that YAGO is an impressive body of work and evidence again of the usefulness of Wikipedia as a source of named entities, categories and relations. WordNet is also an improvement over Wikipedia alone for setting the baseline ontology. According to my initial review, here are the major changes between the first and second (the current) versions of YAGO: -- Facts: 5 M --> 15 M -- Entities: 1.05 M --> 1.7 M -- Relations (predicates): 14 --> 92 -- now exploits infoboxes (a la DBpedia) -- expands concept 'type checking' for QA/QC. But what really impresses me about YAGO is its clean, simple design and the use of "confidence" scores on its facts. This kind of approach will become even more important as additional, "dirtier" data gets incorporated into linked data on the Web. Fabian & Co. deserve the community's thanks! as do you for this nice write-up. Excellent post, Fred!
