High-Definition Semantic Maps (Part IV)

(continued from Part III)

Lately I invested more work in the backend server (TM::IP) to also host the document positions: Positions of those documents which - together with the underlying semantic network - form the landscape.

The theme is still MapReduce, but with considerable more content than before.

Seamless document access

On top of Seadragon I then implemented a bit of mouse hover logic to be able to preview HTML and PDF pages directly onto of the map.

**Play with it!**

But if you break it, you buy it.

What comes next?

Well I certainly know where the topics are on that image. And I also could render the associations! We'll see.

Awesome!

Wow, *now* we're cooking with chili! Awesome stuff. You should make the documents be on by default, though, because once those are on everything makes sense! My only quibble is that seadragon is quite slow, and zooming in doesn't reveal documents in that region (but I'm sure you've thought about that, having documents with high relevance show first, and if you zoom in you display more documents). With some fine-tuning of the preview stuff (doesn't work for PDF's for me; the browser just downloads them) this would seriously rock. Chuck some social networking functionality on top, and you've got a winner.

Awesome, Robert. Well done.

Everybody else; bite! Bite now!

Re: make the documents be on by default ....

Yeah, probably a good idea. Fixed :-)

Re: preview doesn't work for PDF's, browser just downloads

Which browser? And can you remember the link?

The problem is that some websites (again, I am against the death penalty for website owners) choose to send PDF as application/octet-stream.

Some browsers do the right thing and "download" the object. Other browser realize this somehow.

I am keeping track of browser issues at

I have seen already very strange things done by website owners. Again, I am against the death penalty. How many times do I have to say that? :-))

Re: Chrome problems with PDF

I think this is a general issue with Chrome under Linux.
