Query: Online Conversation Disentanglement with Pointer Networks   Huge amounts of textual conversations occur online every day, where multiple
conversations take place concurrently. Interleaved conversations lead to
difficulties in not only following the ongoing discussions but also extracting
relevant information from simultaneous messages. Conversation disentanglement
aims to separate intermingled messages into detached conversations. However,
existing disentanglement methods rely mostly on handcrafted features that are
dataset specific, which hinders generalization and adaptability. In this work,
we propose an end-to-end online framework for conversation disentanglement that
avoids time-consuming domain-specific feature engineering. We design a novel
way to embed the whole utterance that comprises timestamp, speaker, and message
text, and proposes a custom attention mechanism that models disentanglement as
a pointing problem while effectively capturing inter-utterance interactions in
an end-to-end fashion. We also introduce a joint-learning objective to better
capture contextual information. Our experiments on the Ubuntu IRC dataset show
that our method achieves state-of-the-art performance in both link and
conversation prediction tasks.
