There have been some delays, but we are happy to announce that linked data for the 19th World Wide Web Conference in Raleigh, NC, USA, is now available. Why don't you start browsing with the submission that won the best paper award?
At the moment, the dataset includes all full papers. We are planning to add poster and demo submissions soon, as well as some additional metadata for the papers (e.g., links to PDFs and other cross-links).
