Used the FILTER feature of Relfinder to remove seeAlso links from the mix . When you refresh the URL above, I hope you see some aspect of what my initial response and euphoria was about re. progressively generated and enhances Linked Data Spaces. More than anything else, in my world view, Linked Data is about: 1. Loose coupling of Information and Data 2. Ability to explore data relations through your own Context Lenses across their various dimensions. The steps above reduce the cost of "Subjectivity" and "Myopia", two things that always benefit from Information bearing resources that don't provide routes to their data sources. Remember, information is "data in context", and it's inherently subjective :-) BTW - even if RelFinder only had seeAlso links, re. my original comments, don't you see how the graph exposes erstwhile invisible data or serendipitously unveils other relevant things (again very much dependent on the context of the beholder). In my case, I found the keynote-speakers node interesting (amongst others).
