Hi All, Below is the reply I got from Andreas Harth from webdatacommons project. He suggests that the btc-2012 dataset I mentioned in my previous mail has a sufficient FOAF dataset. Shall I go ahead with that dataset for my project?
"the BTC 2012 has FOAF data [1]. You'd get a more comprehensive FOAF dataset if you first get all instances of foaf:Persons (simple grep) and then start a crawl from those, e.g., via LDSpider [2]. I assume that a hop-1 crawl would already get you a sizable dataset. All the best with your project, I look forward to seeing the results! Best regards, Andreas.
