Word-Level Emotion Embedding Based on Semi-Supervised Learning for Emotional Classification in Dialogue

2019

Emotion classification has been remarkable studies in recent years. However, most of works do not consider the context information such as a flow of emotions. In this paper, we propose the emotion classification in dialogue …

Paraphrase Bidirectional Transformer with Multi-task Learning

2020

It is very important to analyze the semantic similarity of two sentences for Natural Language Processing (NLP). This paper proposes a Paraphrase-BERT to perform Paraphrase Identification task. We first fine-tune the pre-trained BERT with MRPC …

Nearest Neighbor Search using Metric-Preserving Function for Retrieval-based Dialogue System

2023

The Nearest Neighbor Algorithm is commonly used in Retrieval-based Dialogue Systems to find the next response candidate for Contexts. In this paper, We experiment with two metric functions for the metric tree-based Nearest Neighbor Search …
