Discussion forums are an important source of information. They are often used
to answer specific questions a user might have and to discover more about a
topic of interest. Discussions in these forums may evolve in intricate ways,
making it difficult for users to follow the flow of ideas. We propose a novel
approach for automatically identifying the underlying thread structure of a
forum discussion. Our approach is based on a neural model that computes
coherence scores of possible reconstructions and then selects the highest
scoring, i.e., the most coherent one. Preliminary experiments demonstrate
promising results outperforming a number of strong baseline methods.Comment: Neu-IR: Workshop on Neural Information Retrieval 201
