Syuzhet Sentiment of Sacred Texts

These graphs show the “emotional valence” or sentiment over narrative time percent. That is, they chart the positive and negative valued sentences from beginning to end.  A positive valued sentence would be, “I feel good.” A negative one of equal value would be, “I feel bad.”  A neutral sentence would be, “I feel okay.”  If […]

Visualizing Vocalization with R

One day I decided that I wanted to have the ability to see a frequency x time “amplitude density” plot of sound – specifically dolphin and bird voices. So the first task was to locate some sounds!  Preferably these should be free from all other sounds, including those from the ambient environment – splashing, microphone […]

Inspecting American Inaugural Addresses with Perl and R

Given all the inaugural  addresses of American presidents, what are the readability stats?  What is the sentiment over time? UPDATE: Results charted for 2017 As usual I reach for perl to acquire and format the data for exploration with R.  The code below (and available on github) reads and analyzes a collection of text documents.  […]

Inspecting the English Premier League Player Stats with R

Visualizing Chatter on a Polar Plot

What does IRC chatter look like on a polar plot, with lines linking the conversations?

Successive Old Faithful Eruption Durations

Because of the observed data, a four group clustering emerges when you plot successive eruption durations, of the famous geyser.  That is, the x axis is the first eruption and y is the next.

After over 15 years of solid LAMP development with Perl and friends, I have finally started to use Python – both as programmer absorbed with the syntactical nuts and bolts, and as scientist manipulating and visualizing data. Frankly, it is exciting.

Visualizing US Presidential Elections

I am a curious cat by nature, and a visual one at that, so back in 2012 I made a little scatter plot of the popular votes in the recent presidential election… { “tl;dr” : “ & 1900 to 2012 elections” }

Secrets and Paranoia! Oh My!

Of all the news I have read about private citizen data being “collected” by the NSA and other government agencies (both domestic and foreign), no one has mentioned that this data is susceptible to leaking *from* those agencies. All the stories I have read point out that governments are violating privacy and specifically the American Bill of Rights by collecting and retaining this […]
