Thread Reconstruction in Conversational Data using Neural Coherence Models
Table 4. Performance on the thread reconstruction task.
['[EMPTY]', '[BOLD] Tree-level Acc', '[BOLD] Edge-level  [ITALIC] F1', '[BOLD] Edge-level Acc']
The COS-sim gets the lowest score on both reconstruction tasks. This means reply structure between two posts does not rely only on their term matching patterns. The other two baselines All-previous and All-first perform quite well on our dataset. This is not surprising since it is very common in this kind of forums that most participants reply either to the previous post or to the first post that asks the question.
