Sentiment Analysis Reveals How the World is Feeling

Friday, November 11, 2011


Researchers have been exploring the possibilities of sentiment analysis in areas other than national security and intelligence.  The availability of large amounts of textual data online makes mood tracking of large groups easier than ever. Bob spoke with Indiana University School of Informatics and Computing Professor Johan Bollen about the different applications for sentiment analysis.

Looks like Bob got it wrong about qualitative research. is a great response to his comments. Maybe it's time for Bob to readdress this topic and issue a correction.

As someone who has worked in research using both qualitative and quantitative research methods, I was very upset listening to Bob describe qualitative research as being unscientific with results that were never statistically significant. He obviously does not understand how qualitative research is necessary when quantitative methods are not producing the necessary data and how the two methods compliment each other. I look forward to listening to the podcast every week as its a show that actually investigates the news in media and keeps away from opinion pieces but now, I'm left feeling very disappointed. So disappointed that I felt the need to leave this comment; the first comment I've left on any comment forum in my life. Please, Bob, if you want to express such a strong opinion, do some research first. Thank you.

Bob disparaged the work of qualitative research in this segment. His comments that qualitative work "gets it right as often as it gets it wrong" suggests that he does not understand the purpose of qualitative research, which is to provide rich descriptions of samples not generalize to larger populations. Further, most early research does not adhere to the positivist expectations of experimental designs; qualitative research offers more than it is given credit for in mass media. Bob needs to learn the merits of both forms of research and not perpetuate simplistic understandings of them.
