In Syria, Uncovering the Truth Behind a Number

Huffington Post Politics writer Matt Easton interviews Patrick Ball, executive director of HRDAG, about the latest enumeration of killings in Syria. As selection bias is increasing, it becomes harder to see it: we have the "appearance of perfect knowledge, when in fact the shape of that knowledge has not changed that much," says Patrick. "Technology is not a substitute for science."

A geeky deep-dive: database deduplication to identify victims of human rights violations

In our work, we merge many databases to figure out how many people have been killed in violent conflict. Merging is a lot harder than you might think. Many of the database records refer to the same people--the records are duplicated. We want to identify and link all the records that refer to the same victims so that each victim is counted only once, and so that we can use the structure of overlapping records to do multiple systems estimation. Merging records that refer to the same person is called entity resolution, database deduplication, or record linkage. For definitive overviews of the field, see Scheuren, Herzog, and Winkler, Data Quality ...
