Special Issue Information

Dear Colleagues,

This Special Issue on computational linguistics and natural language processing (NLP) will highlight cutting-edge work that tackles theoretical and practical problems while bringing together recent developments in these quickly developing domains. The goal of this Special Issue is to present a thorough analysis of the most recent advancements in this field, with an emphasis on creative methods and applications in a range of fields.

The integration of machine learning approaches with NLP is one of the main themes that this Special Issue will explore. It will examine how state-of-the-art methods, such as transformer models and deep learning, are applied to improve the efficiency of NLP systems for tasks such as speech recognition, sentiment analysis, and machine translation. It will also explore the impacts of these technologies on improving the accuracy and efficiency of language models, enabling more natural and human-like interactions with machines.

This Special Issue will focus on using NLP in multilingual and low-resource environments. Current research describes unique ways of processing languages with insufficient data, emphasizing the importance of cross-linguistic transfer and unsupervised learning techniques. These findings show that NLP has the ability to overcome language barriers and promote global communication.

Moreover, this Special Issue will investigate the ethical and societal consequences of the advances in computational linguistics and NLP. Contributions may discuss the potential biases in language models and the need for fair and transparent systems that prioritize user privacy and cultural diversity. These debates highlight the need for more research on the ethical use of NLP technologies in real-world applications.

Overall, this Special Issue will offer a rich collection of research that pushes the boundaries of what is possible in computational linguistics and NLP. It will serve as a valuable resource for academics, practitioners, and students interested in the current state and future directions of these dynamic fields.

Pre-trained language models are typically adapted to downstream tasks via full fine tuning. However, this entails substantial computational and memory overhead. Parameter-efficient alternatives such as Low-Rank Adaptation (LoRA), Quantized Low-Rank Adaptation (QLoRA), and frozen backbone mitigate these costs, but empirical evidence on how their performance–cost trade-offs change under low labeled data in Arabic remains limited. This paper compares four adaptation strategies: full fine tuning, frozen backbone, LoRA, and QLoRA for Arabic binary sentiment classification on the Hotel Arabic Reviews Dataset, using CAMeLBERT-Mix as the pre-trained encoder. The methods are evaluated under a unified experimental setting at three labeled-data levels: the full training set, 100 samples per class, and 25 samples per class. The evaluation metrics are reported as means and standard deviations across five random seeds. At the full-data level, full fine tuning, LoRA, and QLoRA achieve macro-F1 scores between 0.9569 and 0.9579 and are comparable within seed variability, while the frozen backbone exhibits performance that is approximately ten points lower. LoRA and QLoRA use approximately 35.0% less peak GPU memory than full fine tuning but require longer training times. Under reduced-data conditions, full fine tuning outperforms all other adaptation strategies with the differences being statically significant. Full article
