Chat Disentanglement: Identifying Semantic Reply Relationships with Random Forests and Recurrent Neural Networks
Shikib Mehri, Giuseppe Carenini · International Joint Conference on Natural Language Processing · 2017
Thread disentanglement is a precursor to any high-level analysis of multiparticipant chats. Existing research approaches the problem by calculating the likelihood of two messages belonging in the same thread. Our approach leverages a newly annotated dataset to identify reply relationships. Furthermore, we explore the usage of an RNN, along with large quantities of unlabeled data, to learn semantic relationships between messages. Our proposed pipeline, which utilizes a reply classifier and an RNN to generate a set of disentangled threads, is novel and performs well against previous work.
