Coding Disaggregated Intrastate Conflict: Machine Processing the Behavior of Substate Actors Over Time and Space.

This article describes a new machine-coded event data set specifically designed to study the spatially, temporally, and tactically disaggregated actions of multiple state and nonstate actors in a systematic fashion.
