My, as usual a bit off center, take on Sentiment Analysis is posted here: Pinwheel Time, taking the Time out of Social Networking (and leaving the Trends in) [1].

It is a classic "Tides" harmonic analysis, but gives some insights into how to avoid being enslaved by the "news". It does include some cool ways to simplify calculations and do away with the "fortnight" (1/7) harmonic and the observation that groups need no "ordering" alphabetical of otherwise - but they do need C4 Group Symmetry.

Great call :-)

1. I had an observation about claims for the accuracy of Sentiment Analysis. It rather depends on the expectation that opinion is in fact polarized. Many years ago a friend described a similar problem ... She returned home after her Living Room was re-carpeted. So she looked, and found a Husband-sized lump, ignored it, and found a cat sized lump and called the workmen back. The lump size gives an indication of the form underneath a Gaussian. If the expectation is that the form underneath is two poles then the width of the Gaussian shape above is not a reflection of the standard deviation of the sample, but rather a reflection that the sample has no Central Limit (average), something which makes a Gaussian tall and skinny. Three sigma is a sampling rate ~ 99.7% of Tweet Context (Subject), whereas one sigma (~ 68%) assumes every lump has one peak underneath. My method is easier - approximate the lump underneath by an isosceles triangle
 and pivot each half to "see" the expected poles.  Hint: your approximation to the cat sized Gaussian just became an approximation to a catenary.

2. <olyerickson> Overarching question: for all of these papers, do they focus on their immediate countries/regions, the whole" world or a specific interesting country (e.g. USA, UK, EU countries, etc)

I too would like to hear an answer to Mr. Erickson's overarching question ... in this Crowdsourcing Context: Canberra is 13 hours ahead of Texas at the moment. It will soon be Saturday night, here. Nothing says piety like a Sunday morning in Sidney with the contemporaneous input of 20 something million liquored up Cowboys. I foresee some problems in the offing with real time data.

3. Ms. Flagg ... is there a "Time Zero" on the Archival Data Sets from the various suppliers ? The reason I ask is because the archives might be crucial to validate the expectations for success of a Government program, pre-launch. It seems to me that this would make the risk of using a new technology for the Agency, unnecessarily greater, and for you a harder sell.
