One Year of NYC Cab Trips

HubCab followed all NYC Cab pickups and dropoffs in 2011 and created this interactive map with the help of MIT Senseable City Lab

Enter HubCab, a project of MIT Senseable City Lab who captured year’s worth of data from taxi pickups and dropoffs in New York City. The technical development section of HubCab‘s website provides a detailed explanation of the backend required for this level of data processing if you want to nerd out on that, but the interactive map is the clearly the most fun.

The basis of the HubCab tool is a data set of over 170 million taxi trips of all 13,500 Medallion taxis in New York City in 2011. The data set contains GPS coordinates of all pickup and drop off points and corresponding times.

Relationship Status vs. Facebook Use

Previously we have looked at the effect of Facebook on breakups, in that same vein here are three charts showing how relationship status affects posting mood, and frequency.

The Science Behind Selfies

Data-mining the selfie with Selfiecity.com – extensive analysis and an interactive selfie browser

Enter SelfieCity, a website that takes an analytical view at “selfies” taken from users in Bangkok, Berlin, Moscow, New York, and Sao Paolo. The site uses image recognition and analysis to analyze tilt, angle, mood, and all the other things that make the selfie what it is.

This is data-mining and vanity together, at its finest – as well as an interesting use of Amazon’s Mechanical Turk platform.

Get down to the details by seeing the complete analysis and reading some full-length reports on SelfieCity, but most exciting is the interactive selfie browser Selfiexploratory.

Women’s selfies show more expressive poses; for instance, the average amount of head tilt is 150% higher than for men: (12.3° vs. 8.2°). Sao Paulo is most extreme – there, the average head tilt for females is 16.9°

Beach Boys Vocals Visualized

Visualization of The Beach Boys’ ‘You Still Believe In Me,’ using the acoustic voicing principles of bells for a view of the songs’ acoustic properties

I have said it before, and will likely say it again but for me, Brian Wilson represents the pinnacle of composing and recording vocal harmonies. Enter this awesome visualization by Alexander Chen, employing the physics behind bells to show a visual representation of the vocal harmonies in The Beach Boys recording of ‘You Still Believe In Me

Trayvon Tweets – Statistically Speaking

As we are quickly learning in the information age, things are not always as they are presented.

Floatingsheep recently compiled statistical data around the trial, drawing interesting conclusions.

Trayvon Hashtag MohawkUnderstandably, the George Zimmerman trial received a lot of national attention. As a result, the national conversation quickly became focused on issues of racism, southern identity, and the long-term effects of the acquittal of the accused.

The lifespan of these events in our emotional and internet world is short.

All it took was a good night’s rest before everybody jumped back to their normal twitter behaviors, much to the chagrin of Anthony Weiner and a handful of others involved in current events that are not even worth our time.

The South is not as racist as you perceive.

#JusticeForTrayvon Map

Looking at the density of #JusticeForTrayvon tweets across a map of the United States across a two-week period, it doesn’t appear anybody west of the Mississippi perceived an injustice throughout the trial (with the exception of California, which I will attribute to the still salient shooting of Oscar Grant instead of assuming liberal bias.)

Automatic – Driving Assistant

Automatic Driving Assistant uses in-car obd-ii technology to link driving, maintenance, and usage info for your car or vehicle to your iPhone or iOS device

Automatic Driving AssistantiPhone OBD-ii integration has come a long way since we first looked at the integration here a few years ago with CarTrip. What a difference a few years makes! The $70 Automatic includes access to the app and the integrated OBD-ii dongle.

With a highly-refined app, and my well documented obsession with technology and statistics, this is definitely on my to-buy list. I recently added the JawBone Up to my personal repertoire for tracking movement, eating, and sleep and have used Fuelly for a several years to manually track fuel economy and costs, and Waze to manage and track driving / directions. Excited for a solution to combine all these concepts in a good-looking app and give more accuracy than I could get tryIng to cull data manually.

Examining EPL fans via Twitter

An interactive map showing Premier League football fandom by area in the UK

After yesterday’s exciting EPL action, first with Arsenal’s big 5-1 win, followed by Chelsea being Chelsea, this felt like timely  sharing.

Collecting tweets from the period between Aug 2012 and Dec 2012, members of the Oxford Internet Institute gathered information via Twitter and geolocation to see who’s fans are where, and show some quantitative data.

View The Interactive Map

 

The data used include all geotagged tweets mentioning any of the Premiership football teams and their associated hashtags (e.g., #MUFC or #YNWA) that were sent between August 18 and December 19, 2012. We have only included one tweet per user to prevent ‘loud’ fans from skewing the results. The users were then aggregated to postcode districts in order to see a fairly fine-grained geography of results. The number of tweeters per district is normalized by the total ‘population’ of Twitter users based on a 0.25% random sample of all tweets within the UK.

2012 Listening Habits

A glimpse at my listening habits in 2012 as charted by last.fm

This is pretty self-explanatory, every year I try and get a quick snapshot on 1-Jan of the previous years’ listening habits through Last.FM. 2012 was a bit different; I started using Spotify radio playlists, which explains how the Air, Mogwai, and Christopher Cross tunes ended up on the top tracks list for 2012, in the midst of a bunch of seemingly unrelated artists.

The White House Office of Management has approved a request from the National Highway Traffic Safety Administration (NHTSA) to mandate event data recorders, commonly referred to as “black boxes,” in 100-percent of new vehicles sold.

Why Your Mom Keeps Calling / How You Choose Best Friends

Science proves that your mom really does call more often now that she’s older – also, why your tastes in ‘best friends’ change over time. Fun with data mining!

A nice link to Scientific Reports from WaPo today, on a study utilizing cellphone data to analyze how people communicate and age and gender’s role in the process.

Musicians' Guide to Social Media

An excellent treatise on acceptable and effective use of social media for musicians from a good friend, musician, Tricil; one of the few people in Atlanta I can talk shop to regarding the ins and outs of social networking. Too often artists come off sounding self-absorbed or spammy, obviously not their goal but the damage it causes their brand and image can be difficult to reverse.

Twitter finds NYC's 'Happy Place'

The happiest “corner” is actually just inside the western edge of Central Park, where the intersection of 7th and 77th would be (this is just north of the lake and east of the Hayden Planetarium)*. This corner elicits tweets with a relatively high abundance of the positive words “loves” and “sky”, and proportionally less negative words like “not”, “fear” and “no”. Many of the happiest locations actually fall within Central Park!

One of the most interesting applications of Twitter is not the social networking aspect, instead, the sheer amount of data the platform generates and the potential to mine the data to identify and solve problems or uncover interesting facts.

Another excellent example of data mining and data visualization is in this map that purports to show New York City‘s ‘happiest’ place overlaying geotagged tweets and developing a heat-map using keywords, using labMT scoring, are associated with positive or negative emotions.
