Re:What's Going on in Catalonia? on Saturday November 08, 2014 @06:45AM (#8576589)
I'm all for Catalonian independence, but I completely oppose the way scrolling has been hijacked on that page.

here's how you scroll http://bost.ocks.org/mike/scroll/

thanks! that's definitely a good idea, how would you go about doing this? counting @mentions vs "tokens"/workds and setting a threshold ratio to remove tweets?
cool idea - i tried to pick perceptually separate colours and thought blue and red would work, but turns it's confusing for some people. I might add "colorblind" mode and use your colour range.
yep you're right - this is just a cool toy to have a look at what Londoners are up to - the focus isn't scientific, more like "hey what are all those people there tweeting about".
Yes! should be really easy.

i want to do also nyc and sf.

Hey thanks for the feedback, I'll change the "bad" colour to orange - should be easy enough to do!
hey sweet orthographic projection! Yeah, i'm in London.

I'm only using tweets on which users chose to publish their locaiton, so it isn't all of the tweets, but a good chunk of them.

well, i have to say the mapping of colours to concepts is highly cultural, so in some places it means anger, or war, or love or joy.

I chose red and blue because they're quite perceptually separated, so it's easy to point them out on the map.

Yep, i realised that - but node-sentiment was pretty quick to implement and gives alright results, so it's a bit of a tradeoff. Do you know of more accurate sentiment analysis services?
Hi HN.

I've built a map that takes a geofenced stream of tweets and runs AFINN-111 sentiment analysis on them, and then displays them in real time on a map of London.

Negative sentiments are displayed as Red tweets, happy tweets are Blue.

The whole thing is built on node.js using node-tweet-stream, node-sentiment and socket.io. The frontend map is leaflet with stamen design's Toner tiles.

It's quite fun to watch, especially when there's a football match or a concert. If you click on the "follow tweets" checkbox, new tweets pop up as they arrive, although currently that makes the map pan north.

Thanks!

Dario.
