Computational analysis of text...
and it's uses in Journalism!
by: Dhrumil Mehta
Text as Data
A Few Examples
The Media Really Has Neglected Puerto Rico
The Media Really Started Paying Attention To Puerto Rico When Trump Did
Apple says its App Store is ‘a safe and trusted place.’ We found 1,500 reports of unwanted sexual behavior on six apps, some targeting minors.
He was caught on video, but Georgia doctor kept his medical license
A small group of lawyers and its outsized influence on the U.S. Supreme Court
The Echo Chamber
Why is this interesting?
Because AI?
Title Text
Because it is another tool for
empirically guided inquiry,
which is common to Journalism and Social Science.
Data journalism:
"Quantitative social science...on deadline."
- Andrew Flowers (former 538 quantitative editor)
But the "on deadline" part can be tricky...
Which is partly why methodological innovation is so hard to do in newsrooms, and often the new and innovative methodologies are limited to large newsrooms with time and space to experiment or with the power to put resources behind large enterprise projects.
... and even then we're often leaning on the work of our colleagues.

What is it not good for?

Using a new methodology:
- What has/could it be used for in journalism?
-
What are the pitfalls specifically to journalistic inquiry?
-
How do we edit a story that uses this methodology?
-
How do we communicate the methodology readers?
-
How do we communicate the pitfalls to readers?
Example 1:
"Research shows that minority candidates can be successful in drawing out co-ethnic minority voters....
...but it is difficult to draw any conclusions from the research about national elections, in which partisanship is a much stronger force."
Empirically guided inquiry wasn't possible using our go-to methods:
There is only one poll I know of that breaks out a "South Asian American" cross-tab...
...and it comes out once every few years.
During Jindal’s first gubernatorial campaign, in 2003, South Asian-Americans donated an estimated $667,000, or 19 percent of the $3.5 million he raised from individual donations.
During his much more expensive 2007 and 2011 campaigns, that figure dropped by about half and made up only about 4 percent of the approximately $8 million that he raked in from individual donors during both of those campaigns.

It's hard for newsrooms to do this kind of work regularly without a template for it.
- There is only so much methodological innovation our editorial process can handle. The edit-burden for introducing a new methodology has to be justified by the importance or the story due to deadline / bandwidth constraints.
- There is an "uncanny valley" of stories that could push the envelope in terms of methodology that can't get done because they require more innovation than can be justified (the first time).
Journalism Schools are well-placed to pioneer methodological innovation.
- Co-location with academics of from disciplines makes taking inspiration from other disciplines easier
- It's exciting work for student projects (and makes for great portfolio pieces)!
- Students often spend several weeks on a project or two...there is room for iteration.
- J-schools are well placed to take knowledge from across newsrooms who are doing this kind of work, and consolidate / explain / democratize / "templatize" it for newsrooms.
And interdisciplinary collaboration is a two-way street...

Political Communication: Methods
That's one of the things I'd like to do if I were at Columbia...
Work across disciplines to identify methods of empirical inquiry that could be useful to journalists. Work with students on interesting stories using those methods and then make those methods accessible to newsrooms.
And while it's important for students to participate in innovation...
...it is equally important for them to be trained in the fundamentals of computational journalism.

New research from the University of Washington finds that a natural aptitude for learning languages is a stronger predictor of learning to program than basic math knowledge, or numeracy.

DPI-691M: Programming and Data for Policymakers
(aka. #code4policy)
Data and code are no longer just for programmers. Policymakers in the 21st century, from members of congress to analysts and executives need to be equipped with the necessary skills to navigate nuanced issues at the intersection of technology and governance.
Those who have first hand experience with programming, data, software development and management, methods, open source collaboration, and technology innovation are better prepared to competently navigate these issues.
Curriculum Design
Programming and data for Policymakers
(#code4policy)
- Not just "learning a technology" but "Learning how to learn new technologies."
- Project-based learning
Learning Objectives:
"Learning how to learn new technologies."
- Having a mental-model of what is going on rather than blindly entering commands
- Reading technical documentation.
- Logically formulating a question when you're stuck based on your mental model of what is happening
Lesson Planning
-
Non-project lessons are strictly tethered to learning objectives.
-
Lessons are built to promote conceptual understanding
- ...or to train "muscle memory" for good habits
"Learning how to learn new technologies."

Dhrumil's Classroom
Sticky Notes Everywhere!
Student Feedback
- Daily Standup Meeting (class & projects)
- What have you done since the last class?
- What do you plan to do between now and the next class?
- Any blockers?
- Sticky Notes for Workshops
- Blue when you're done, or feeling a sense of mastery
-
Red when you're stuck, or feeling lost
- Parking Lot Questions
Learning Together
- Coding "I do" vs "You Do"
- Pair programming
- Driver - Writing the code
- Navigator - Figuring out what to do next
- Project-based learning
- An active Slack group...
Inclusion
Fear of technology- Systems like Blue / Red sticky notes in place to promote inclusion...no student should feel this is not for them.
"Dhrumil did a fantastic job of not only lining up great speakers for the class, but achieving gender parity among his guests - an impressive feat in the male-dominated tech sphere!"

This class gave me more confidence to pursue possible jobs in being a bridge between technology teams and social service delivery. It also sparked my interest in mastering some skills in the course we didn't get to practice but seem valuable, like scraping for data or utilizing and API.
---
I gained confidence that I am able to get to grips with new technologies/ software on my own and tools for doing so in a systematic way.
Rigor
This was a great class and I really enjoyed taking it! I had to work surprisingly hard, but felt like that learning was purposeful. I feel proud of my final project and am grateful to have had the opportunity to work on it.
