This repository contains implementations for three conversational emotion detection methods, namely:
Unlike other emotion detection models, these techniques consider the party-states and inter-party dependencies for modeling conversational context relevant to emotion recognition. The primary purpose of all these techniques are to pretrain an emotion detection model for empathetic dialogue generation.
Fig. 1: Interaction among different controlling variables during a dyadic conversation between persons A and B. Grey and white circles represent hidden and observed variables, respectively. P represents personality, U represents utterance, S represents interlocutor state, I represents interlocutor intent, E represents emotion and Topic represents topic of the conversation. This can easily be extended to multi-party conversations.Emotion recognition can be very useful for empathetic and affective dialogue generation -
These networks expect emotion/sentiment label and speaker info for each utterance present in a dialogue like
Party 1: I hate my girlfriend (angry)
Party 2: you got a girlfriend?! (surprise)
Party 1: yes (angry)
However, the code can be adpated to perform tasks where only the preceding utterances are available, without their corresponding labels, as context and goal is to label only the present/target utterance. For example, the context is
Party 1: I hate my girlfriend
Party 2: you got a girlfriend?!
the target is
Party 1: yes (angry)
where the target emotion is angry. Moreover, this code can also be molded to train the network in an end-to-end manner. We will soon push these useful changes.
TL-ERC: Emotion Recognition in Conversations with Transfer Learning from Generative Conversation Modeling
TL-ERC is a transfer learning-based framework for ERC. It pre-trains a generative dialogue model and transfers context-level weights that include affective knowledge into the target discriminative model for ERC.

DialogueGCN (Dialogue Graph Convolutional Network), is a graph neural network based approach to ERC. We leverage self and inter-speaker dependency of the interlocutors to model conversational context for emotion recognition. Through the graph network, DialogueGCN addresses context propagation issues present in the current RNN-based methods. DialogueGCN is naturally suited for multi-party dialogues.

Note: PyTorch Geometric makes heavy usage of CUDA atomic operations and is a source of non-determinism. To reproduce the results reported in the paper, we recommend to use the following execution command. Note that this script will execute in CPU. We obatined weighted average F1 scores of 64.67 in our machine and 64.44 in Google colaboratory for IEMOCAP dataset with the following command.

DialogueRNN is basically a customized recurrent neural network (RNN) that profiles each speaker in a conversation/dialogue on the fly, while models the context of the conversation at the same time. This model can easily be extended to multi-party scenario. Also, it can be used as a pretraining model for empathetic dialogue generation.
Note: the default settings (hyperparameters and commandline arguments) in the code are meant for BiDialogueRNN+Att. The user needs to optimize the settings for other the variants and changes.

DialogueRNN: An Attentive RNN for Emotion Detection in Conversations. N. Majumder, S. Poria, D. Hazarika, R. Mihalcea, E. Cambria, and G. Alexander. AAAI (2019), Honolulu, Hawaii, USA
Interactive COnversational memory Network (ICON) is a multimodal emotion detection framework that extracts multimodal features from conversational videos and hierarchically models the \textit{self-} and \textit{inter-speaker} emotional influences into global memories. Such memories generate contextual summaries which aid in predicting the emotional orientation of utterance-videos.

CMN is a neural framework for emotion detection in dyadic conversations. It leverages mutlimodal signals from text, audio and visual modalities. It specifically incorporates speaker-specific dependencies into its architecture for context modeling. Summaries are then generated from this context using multi-hop memory networks.

bc-LSTM-pytorch is a network for using context to detection emotion of an utterance in a dialogue. The model is simple but efficient which only uses a LSTM to model the temporal relation among the utterances. In this repo we gave the data of Semeval 2019 Task 3. We have used and provided the data released by Semeval 2019 Task 3 - "Emotion Recognition in Context" organizers. In this task only 3 utterances have been provided - utterance1 (user1), utterance2 (user2), utterance3 (user1) consecutively. The task is to predict the emotion label of utterance3. Emotion label of each utterance have not been provided. However, if your data contains emotion label of each utterance then you can still use this code and adapt it accordingly. Hence, this code is still aplicable for the datasets like MOSI, MOSEI, IEMOCAP, AVEC, DailyDialogue etc. bc-LSTM does not make use of speaker information like CMN, ICON and DialogueRNN.
