摘要

摘要

En 中文
When we talk about the coherence of a story, we seem to think of how well its individual pieces fit together-how to explicate this notion formally, though? We develop a Bayesian network based coherence measure with implementation in R, which performs better than its purely probabilistic predecessors. The novelty is that by paying attention to the network structure, we avoid simply taking mean confirmation scores between all possible pairs of subsets of a narration. Moreover, we assign special importance to the weakest links in a narration, to improve on the other measures' results for logically inconsistent scenarios. We illustrate and investigate the performance of the measures in relation to a few philosophically motivated examples, and (more extensively) using the real-life example of the Sally Clark case.
