GeoBLR – PIN Code Extravaganza!

Last week at GeoBLR we discussed the issues around PIN codes. The most  important questions were around the processes the postal system and also what are the issues around the availability of reliable spatial data.

Couple of weeks back, Nisha and I started putting together several questions that we would like to get insights on. We used that as the starting point for the discussions. The meat of the problem really is that nobody knows what the processes are and how to get that information.

Prior to GeoBLR, we met some people who are interested in the same issue and clarified a lot of things – for instance, we are now sure that some times a single post office can deal with more than one PIN code.

To get a sense how people felt about the PIN codes issues, we asked around. Some people don’t bother to use PIN codes for any substantial service other than sending post cards.  As long as we are not able to tie PIN codes to geographic locations reliably, it’s not so useful.  Everybody agrees that it has immense potential just because it’s the only part of the address that everybody gets right (most of the time).

We also started to brainstorm how to come up with a plan so that a group like ours along with several other partners could work together to attempt to crowdsource the issue. Read more about the plan and next steps here!

You can see the notes on the DataMeet HackPad and Thej’s presentation here.  The topic was getting data from large scale telephone data collection methods.  Thej shared his experience using these techniques on a political campaign and at NextDrop.

It was a really great meeting and we had an interesting conversation on what tools to use to for what, what was effective and also methodology strategies.

Looking at telephone related data collection some of the interesting findings regarding the response rates to different outreach techniques.

Response rates from out reach techniques:
Responses to SMS – 6 to 8%
Responses to missed call – 12%
Responses to IVR – 20 to 25%
Some big questions regarding telephonic data collection. Are people comfortable giving out their numbers? Seems they are as long as you represent yourself in a straightforward manner and convey that people will get information from doing this.
What are the ethical ways to get contact information and demographic information? There are many ways to get this information but it might be worth doing your own baseline, data collection first to build trust and get cleaner data.
There are more great insights in the notes and the presentation feel free to look them over and ask questions in the comments.

Data Science meets Data Technology

Data Science meets Data Technology
The Big Picture
August 18th, 2012
10:00 AM – 12:30 PM
Conference Room 2
NIAS, Bangalore

While data is increasingly important in academia as well as in industry, the two worlds do not intersect each other all that often. DSDT is a monthly forum for sharing ideas about data across disciplines and industries. Each DSDT meeting will consist of two talks on a common theme, pairing a data scientist with a data technologist along with time for discussion. From the second session onward, we will have a tutorial and hacking session after the talks where we will learn how to work on understanding and analysing data sets relevant to that meeting’s theme. The schedule for the first meeting on the 18th at NIAS is given below.

10:00 AM – 10:30 AM: Tea
10:30 AM – 11:00 AM: Analysis: The Big Picture. Rajesh Kasturirangan, NIAS.
11:00 AM – 11:15 AM: Discussion of talk 1.
11:15 AM – 11:45 AM: Data and Visualization: The Big Picture. S. Anand, Gramener.
11:45 AM – Noon. Discussion of talk 2.
Noon – 12:30 PM: General Discussion.
