Reading Between the Lines: Prediction of Political Violence Using Newspaper Text

Hannes Mueller and Christopher Rauh ()

No 11516, CEPR Discussion Papers from C.E.P.R. Discussion Papers

Abstract: This article provides a new methodology to predict armed conflict by using newspaper text. Through machine learning, vast quantities of newspaper text are reduced to interpretable topics. We propose the use of the within-country variation of these topics to predict the timing of conflict. This allows us to avoid the tendency of predicting conflict only in countries where it occurred before. We show that the within-country variation of topics is an extremely robust predictor of conflict and becomes particularly useful when new conflict risks arise. Two aspects seem to be responsible for these features. Topics provide depth because they consist of changing, long lists of terms which makes them able to capture the changing context of conflict. At the same time topics provide width because they summarize all text, including coverage of stabilizing factors.
