An example of topic splitting as inferred through the use of the KLD by our algorithm but which is undetected by the previously proposed BHD-based relatedness: a magnification of the salient window region in our interactive application used to explore large longitudinal text corpora (described in Section 3.3) showing the split topic and its descendant topics and b the split topic and its descendent topics shown as word clouds. Recall that the notion of topic splitting as used in this work differs significantly from that used in previous work. As argued in Section 2.2, the previous understanding of topic splitting is better described as topic speciation
