 Enhancing Textual Data Augmentation Techniques: A Comprehensive Exploration

Abstract:

Textual data augmentation has emerged as a crucial technique in natural language processing (NLP) to enhance model performance, especially in scenarios with limited labeled data. Augmentation methods manipulate existing text data to generate additional samples, thereby diversifying the dataset and improving model generalization.

Information

This article comprehensively explores various textual data augmentation techniques, ranging from traditional methods like synonym replacement and paraphrasing to advanced approaches leveraging deep learning and pre-trained language models.

 We delve into the theoretical foundations, implementation strategies, and practical considerations of each technique, providing insights into their effectiveness, limitations, and application domains. Additionally, we discuss challenges, future research directions, and ethical considerations in textual data augmentation. By synthesizing existing knowledge and insights, this article serves as a valuable resource for researchers, practitioners, and enthusiasts interested in advancing NLP through effective data augmentation techniques.
