Another Day of Hope (mostly), and some Fear and Worry in the US

Today I checked on the mood of the US Population through Twitter, using Twitter’s Geotagging feature. Alan Mislove from Northeastern had already found that the mood of the nation changes over the course of the day, with people having a low over lunch, and getting collectively happier in the evening, when work is over. Using our Twitter-collector-tool built into Condor, I was able to easily replicate this result.

I counted the number of retweets about “hope”, “fear”, and “worry” in the major population centers of the US, by collecting the tweets at four 2000 kilometers circles with centers at Pittburgh (North East), Atlanta (South East) Las Vegas (South West), and Boise (North West). (see picture below) I then constructed the social network between the retweeters as described in a previous blog post. The way it is calculated, it also factors in the importance of the retweeters, where a link is drawn between two people if a person retweets a post from the other person.



The picture above shows the areas I covered, as well as the fraction of retweets on hope (green), fear (blue), and worry (red) around noon. As we can see, people are more hopeful in the West around noon EST (which is still in the morning in the West) than they are on the east coast.
The picture changes four hours later. The graph below shows hopefulness (fraction of retweets on hope/fractions of retweets on fear and worry) around noon EST and around 6pm EST. Hopfulness shoots up sharply in the Northeast (NE), Southeast (SE), and Southwest (SW). It also goes up in the Northwest (NW), although much less.

Note that there are always more retweets on hope than there are on fear or worry, showing that people are basically hopeful, particularly when work is over. Let’s hope that hopefulness will also go up in the evening in the Northwest!

    How do you figure out if a tweet is about hope or worrying etc?

    How do you detect sarcasm, e.g. I just got a speeding ticket, oh i'm so happy now"?

    I don't detect sarcasm - my experience is that while there are indeed sarcastic or cynic comments, the majority is not, so sarcasm drowns in the sea of straightforward tweets

    Hello, I'm doing a research about cool hunting and I desperately need some scientific articles about the issue (from marketing magazines, etc..) can you help me out on this matter? Do you know some good articles?

    Thanks.

Predicting Stock Market Indicators Through Twitter “I hope it is not as bad as I fear”

Image
We have been working on trying to predict market indicators for quite some time by analyzing Web Buzz , predicting who will win an Oscar, or how well movies do at the box office . Among other things we have correlated posts about a stock on Yahoo Finance and Motley’s Fool with the actual stock price, predicting the closing price of the stock on the next day based on what people say today on Yahoo Finance, on the Web and Blogs about a stock title. The rising popularity of twitter gives us a new great way of capturing the collective mind up to the last minute. In our current project we analyze the positive and negative mood of the masses on twitter, comparing it with broad stock market indices such as Dow Jones, S&P 500, and NASDAQ. We collected the twitter feeds from one whitelisted IP for six months from March 30, 2009 to Sept 4, 2009, ranging from 5680 to 42820 tweets per day. According to twitter this corresponds to a randomized subsample of about one hundredth of the full volum...

My life in Alternative Realities - fatherlanders and nerds don’t go well together

Image
We are all living in different alternative realities, people with different personalities see reality from very different perspectives, potentially leading to a lot of friction and misunderstandings. “Nerds” are open to change, they believe in the progress of technology and innovation. “Fatherlanders” abhor change, they like tradition and authority, valuing the fatherland above all, and would like to reestablish the good old times. “Spiritualists” believe into supernatural forces, they are religious, meditate and hope that the forces of nature will heal their ailing. “Treehuggers” believe into sustainability and global warming, they want to save nature by restricting technical progress. I experience  this friction frequently in my daily life. As a computer and technology nerd with spiritualist and treehugger inclinations, my communication with members from other tribes sometimes does not end well.  My interactions with officers of the US Department of Homeland Security and the...

How Blind Trust in Generative AI Undermines Creative Work

Image
This summer, we experienced firsthand the damage caused by blind faith in the "superhuman" capabilities of generative AI, even among otherwise intelligent individuals. Here's what happened. We submitted a research paper to an academic conference, and after it was accepted, I paid the registration fee, booked flights, and arranged accommodations. A week later, we received an abrupt email from the organizers stating that our paper had been rejected. The reason? Their AI-based plagiarism and ChatGPT-detection tool flagged it as containing both plagiarized content and text generated by ChatGPT. This accusation was entirely unfounded. Our paper presented highly original work by our team, proposing novel AI algorithms to predict animal emotions—a concept never explored before. We detailed the development of an AI model to validate this approach, something completely unique to our research. By its very nature, it was impossible for our work to be plagiarized or generated by Chat...
