ConText at WASSA 2024 Empathy and Personality Shared Task: History-Dependent Embedding Utterance Representations for Empathy and Emotion Prediction in Conversations

no code implementations4 Jul 2024 Patrícia Pereira, Helena Moniz, Joao Paulo Carvalho

In our submissions, we model empathy, emotion polarity and emotion intensity of each utterance in a conversation by feeding the utterance to be classified together with its conversational context, i. e., a certain number of previous conversational turns, as input to an encoder Pre-trained Language Model, to which we append a regression head for prediction.

Fuzzy Fingerprinting Transformer Language-Models for Emotion Recognition in Conversations

no code implementations8 Sep 2023 Patrícia Pereira, Rui Ribeiro, Helena Moniz, Luisa Coheur, Joao Paulo Carvalho

Fuzzy Fingerprints have been successfully used as an interpretable text classification technique, but, like most other techniques, have been largely surpassed in performance by Large Pre-trained Language Models, such as BERT or RoBERTa.

Simple LLM Prompting is State-of-the-Art for Robust and Multilingual Dialogue Evaluation

1 code implementation31 Aug 2023 John Mendonça, Patrícia Pereira, Helena Moniz, João Paulo Carvalho, Alon Lavie, Isabel Trancoso

Despite significant research effort in the development of automatic dialogue evaluation metrics, little thought is given to evaluating dialogues other than in English.

Context-Dependent Embedding Utterance Representations for Emotion Recognition in Conversations

1 code implementation17 Apr 2023 Patrícia Pereira, Helena Moniz, Isabel Dias, Joao Paulo Carvalho

The usual approach to model the conversational context has been to produce context-independent representations of each utterance and subsequently perform contextual modeling of these.

Towards a Sentiment-Aware Conversational Agent

no code implementations24 Jul 2022 Isabel Dias, Ricardo Rei, Patrícia Pereira, Luisa Coheur

In this paper, we propose an end-to-end sentiment-aware conversational agent based on two models: a reply sentiment prediction model, which leverages the context of the dialogue to predict an appropriate sentiment for the agent to express in its reply; and a text generation model, which is conditioned on the predicted sentiment and the context of the dialogue, to produce a reply that is both context and sentiment appropriate.

Retrieval Augmentation for Deep Neural Networks

1 code implementation25 Feb 2021 Rita Parada Ramos, Patrícia Pereira, Helena Moniz, Joao Paulo Carvalho, Bruno Martins

Despite the use of large training datasets, most models are trained by iterating over single input-output pairs, discarding the remaining examples for the current prediction.
