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

Nokia Internet Pulse on a scale of
1 to 7 ranging from “Very much
not” to “Extremely very much
indeed”

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

Notes de l'éditeur NIP is a skunkworks system that has been running for three years. So on the back end it’s a big collection of Python scripts. And thanks to Ayman for his help figuring this out Deployed in lab kitchen Deployed in lab kitchen PDC = Participatory Design Conference. And Professional Darts Association. Stage 1 of redesign by professionals. Plus branding made us change our name. Stage 1 of redesign by professionals. Plus branding made us change our name. Stage 1 of redesign by professionals. Plus branding made us change our name. It’s been running for three years. After being rejected from alt.chi and case studies last year But we didn’t crash any servers. We didn’t get 150M twitter users using it. We didn’t even get Eric Gilbert using it. That would have been nice.
