Crosslingual Gap (GAP) A low CNPMI score could indicate a topic pair where each language has a monolingually coherent topic but that are not about the same theme (Topic 6 in Figure 1).
we add two features to capture this information using the Bible: mismatch coefficients (MC) and internal comparison coefficients (ICC): where α is a smoothing factor (α = 0.001 in our experiments).
