Hi Barry, your project - of course I agree :-) However, I don't really see what e.g. GATE would have to do with providing linked data in any different way than Stanbol. Like Stanbol, it is also a framework and API, so I'd move this to Chapter 5 as well. Now reading the abstract on your

Dear all, visualisation is obviously a very hot topic currently and there are a lot of tools and implementations, which provide different level of support. Some simply do a graph visualisation based on the links, other provide multiple visualisation forms to choose from. What I will try to do

We have built a tool to visualize SPARQL results. It is called DaViz [1]. The emphasis was on providing a wizard that can suggest a proper visualization for the data structure. It also has the ability to do pivoting by letting the user drop on column on another. Demo site: [2]. We also made a

Yes and no. We first introduce a generic (read DBpedia with improved disambiguation) service over GATE that's shortly to be released open source called LODIE - this gives an opportunity to discuss precision and recall. We then present building a custom GATE pipeline which can be uploaded

Hi. As I said, great initiative. Do you have a section or chapter about where Linked Data has delivered an enhanced user experience to existing web sites, rather than providing the whole experience? This is an important aspect for the eventual utility of Linked Data, although hard to capture.
