Developments in Event Data

By John Beieler and Andy Halterman The two of us, along with Phil Schrodt, Patrick Brandt, Erin Simpson, and Muhammed Idris have been working on several interrelated projects that we believe will improve the availability and quality of event data. We've discussed these projects formally at ISA and informally at MPSA and elsewhere. But we … Continue reading Developments in Event Data

Data Churn and Data Versioning

Jay Ulfelder has a very nice post about the problems that applied researchers face when working with data that changes rapidly in its availability and production. I agree with the suggestions he proposes (which were, very roughly, 1. modularity in applied uses, 2. transparency in generating data, and 3. awareness of the larger data ecosystem), … Continue reading Data Churn and Data Versioning

The Good Judgement Project and Bayes’ Calculator

It's been a very forecast-y week. Between (finally) reading Phil Tetlock's excellent Expert Political Judgement, going to a half dozen panels at ISA on forecasting and event data, and today's NPR story about the Good Judgement Project, I've been thinking a lot about how to make political forecasts and how we know when they're good. … Continue reading The Good Judgement Project and Bayes’ Calculator

Subsetting and Aggregating GDELT Using dplyr and SQLite

Edit 17 Sept to reflect changes in dplyr's syntax GDELT is an incredible resource for researchers and political scientists and has been getting increasing attention in popular publications. But weighing in at more than 60 GB, it's too hefty for any kind of quick analysis in R, and is even cumbersome to subset in Python. The … Continue reading Subsetting and Aggregating GDELT Using dplyr and SQLite

Subsetting GDELT for Domestic Events

Update: This post is only useful if you're using the reduced dataset. The complete dataset includes an ActionGeo_CountryCode field that you can easily use to pull only events occurring in a country of interest. I recommend using the full dataset. As part of a project examining the effects of U.S. democracy and governance assistance on … Continue reading Subsetting GDELT for Domestic Events
