One of the focuses of interest for conflict research is crisis
forecasting. While the approach often favored by the media and public
approaches this challenge qualitatively with the help of pundits illustrating
effects in a narrative form, quantitative models based on empirical
data have been shown to be able to also provide valuable insights into
multidimensional observations.
For these quantitative models, Bayes networks perform well on this
kind of data. Both approaches arguably fail to meaningfully include all
relevant aspects as
– expert knowledge is difficult to formalize over a complex multidimensional
space and often limited to few variables (e.g. more A will
lead to less B)
– empirical data can only tell us about things that are easily measurable
and can only show correlations (in contrast to causalities that
would be important for forecasting)
In this paper we will develop a method for combining empirical time
series data with expert knowledge about causalities and “hidden variables”
(nodes that belong to variables that are not directly observable),
thereby bridging the gap between model design and fitting.
We build a toolset to use operationalized knowledge to build and
extend a Bayes network for conflict prediction and, model unobservable
probability distributions. Based on expert input from political scientists
and military analysts and empirical data from the UN, Worldbank and
other openly available and established sources we use our toolset to build
an early-warning-system combining data and expert beliefs and evaluate
its predictive performance against recordings of past conflicts.
