This is the talk from the CHI 2012 Long Case Study called "Nokia Internet Pulse: A Long Term Deployment and Iteration of a Twitter Visualization". Abstract Nokia Internet Pulse is a system for visualizing current discussion around a particular topic on Twitter. It consists of a time-series of stacked tag clouds consisting of the (interesting) words in tweets that match a topic. Words are sized proportional to frequency and colored according to the emotional content of the tweet: if several people tweet “I love my Nokia N900”, then “N900” will show up colored bright green, because it’s in the same tweet as the word “love”, which the system recognizes as positive. In addition to showing topics of corporate interest (“Nokia”, “N9”, etc.), the system is also useful for understanding buzz around individuals (“Rihanna”), conferences (“#chi2012”), topics (“rumor OR rumors”), Twitter-specific phenomena (“RT”) and more. Clicking on words shows a list of tweets that contain those words, allowing easy drill-down to view individual tweets. It is available at http://nip.nokia.com/

4. How it works (1): gather
First we collect tweets using Twitter‟s streaming API filter:
keywords = { “nokia”:[“nokia, lumia, asha, phone”],
“chi2012”:[“chi2012, chifilter”],…}
filter = keywords.values()
d=urllib2.Request('https://stream.twitter.com/1/statuses/filt
er.json',"track="+filter)
open(YY+"/"+MM+"/"+DD+"/"+HHMM+".result",’a’).write(d)
Then we sort them into files:
for json.load(tweet) in open(file):
for keyword in keywords:
if keyword.values() in tweet:
keywordyymmdd.write(tweet)

5. How it works (2): sentiment, words
Then we remove stopwords and use a heavily edited version
of the Pitt MPQA to identify a summary of sentiment for each
tweet, producing a words file, ~50 words for each
hour, day, and last-day, last-week:
{ "words": [
{"phone": {"count": 57, "sentiment": 0.15384615384615385}},
{"astound": {"count": 26, "sentiment": 1.0}},
{"c7": {"count": 28, "sentiment": 0.65384615384615385}},
{"use": {"count": 33, "sentiment": 0}},…

6. How it works (3): tweets by
topic
And an (annotated) tweets file for each of those keywords
{ "tweets": [
{"phone": [

7. How it works(4): the front end
• Multiple front ends on the same json-producing backend:
• The desktop Flash version you saw earlier
• Which has multiple versions:
• One for the internet
• One for the intranet (more searches! More sekrit!)
• One for the big screens in the kitchens (some optimizations)
• One for Sesame Workshop‟s offices in NYC
• The Windows Phone version (currently Nokia-internal)
• A now-defunct S60 phone version

25. What constitutes success?
• We designed, iterated and built a system which has been running
for three years and is still running
• Hundreds of people have used thousands of times in our kitchen
and around our lab in Palo Alto
• NIP screens are on every floor of our new building in Sunnyvale
• We officially Technology Transferred to User & Operator Insights
• We worked with great people inside and outside Nokia and spent
a lot of time thinking through the implications of big data
• The CTO took Anita and I out for a really seriously good dinner
with an excellent bottle of amerone
• In an intangible but important way, we got the company thinking
seriously about what people are saying about us in social media
