Things I Learned this Week

Among the things I learned this week:
* Spotify audio quality isn’t as good as I expected, despite knowing the format. I suspect it is a non-issue for most people. (Courtesy: Spotify)

* Weddings benefit from having Baltimore-based attendees: They know how to dance and they play good music. (Courtesy: MLs)

* According to excellent, interesting, insightful, and important research by Byers, Mitzenmacher, and Zervas, daily deals carry a reputational cost to the sponsoring establishment. Specifically, Yelp reviewers who went to an establishment due to a Groupon or LivingSocial coupon, reviewed the establishment 10 percent lower than non-daily deals reviewers. The paper also sheds light and raises questions about the sales dynamics of daily deals and social network effects on these types of sales. I only wish they had better controlled for the Yelp reviews by comparing daily deal establishments with non-daily deal establishments across the same time; not only is this relevant methodologically, but it is also something of interest to me.

* Chinese shadow play is cool, but lacks the unmatchable brilliance of gamelan, the music that accompanies Indonesia’s shadow play–wayang kulit. (Courtesy: Tangshan Shadow Puppet Theatre)

* Karen O, like me, is getting into opera. (Courtesy: Yeah Yeah Yeahs)

Beating a Dead Horse: NYT Article on Collecting Phone Data to Track Public Services is a Press Release

A June 6, 2011, article by Joshua Brustein in The New York Times read as a press release for the private corporations wanting to use cell phone data to monitor and track public services. The article outlines companies that want to collect and data mine behavioral information from cell phones that have those companies’ apps. For example, you have the FPrivacy app by LastLaugh, Inc., and LastLaugh collects your cell phone location and activity, and then uses that data to monitor travel times between different points (e.g., traffic reports, determining when a given subway train will reach its destination). While the idea is interesting, the article essentially regurgitates company press releases and fails to look critically at the idea in at least three simple areas: the role of the public sector, alternative ideas, and privacy. In the eyes of the Facebook generation, an even graver mistake is that it is old news!

Missing Item 1: Where is Local Government?
The article did not even tease the reader with the notion that the local government, through the various agencies that manage public transportation, ought to be providing services that increase our understanding of public transportation, including when to expect the next train. The combination of the right’s dismissal of government having a legitimate place in our lives and the left’s inability to firmly push government agencies to smartly and quickly adopt useful technologies means that we do not think of the government as being an appropriate actor for these types of initiatives.

Missing Item 2: Alternative Ideas
Somewhat related to Missing Item 1 is the fact that the article fails to suggest alternative ideas, whether those ideas are real or on e-ink. Furthermore, we have an incredibly inelegant solution (for these types of problems) in the use of tens of thousands of cell phones as data collectors. For example, there is a significant imputation problem in that for many commutes, “the system” has to make a(n educated) guess about which train or mode of transportation the phone took. Even the article mentions this:

If a phone located near Times Square suddenly loses service and reconnects at Prince Street and Broadway 15 minutes later, then it has almost certainly traveled there using the N or R trains.

A specific cut at this imputation issue is the fact that the approach aggregates very general/inexact data when what is desired is very precise data. This is because what matters is not the activity of an individual psuedo-anonymous cell phone, but the activity of an individual known public transportation vehicle. As a result, the data demands a host of assumptions that fight against the wall of ecological fallacies and other methodological issues.

An alternative idea is to simply equip public transportation vehicles with tracking equipment. At that point, the most precise data possible is collected and aggregating up to more general levels becomes easier. Furthermore, there are no privacy concerns. Even better, many public transportation systems already have this capability!

Missing Item 3: Privacy
Okay, privacy is mentioned, but only in the final sentence of the article:

This could be a challenge, as it is clear that many people are uncomfortable with technology companies or government agencies tracking their every move.

Perhaps I should be thankful, since Brustein finally brings the public sector into the discussion. Instead, though, I ask myself, “That’s it?” The article talks about (admittedly, opt-in) methods for tracking every location and travel route a person’s cell phone takes, as well as every conversation one has*, but the only love privacy is shown is a single sentence that reads as if it was written by a junior-high student.

* One company wants to use phones’ microphones to identify locational atmospherics, a method that is smeared with a smile by phrasing it as a way to determine whether you are on a bus.
