In the era of rapidly growing digital information, the classification of unstructured data from sources, e.g., Internet news articles, has become increasingly challenging. This study introduces the Turkish Retentive Network (TurkRetNet), a novel neural network architecture implemented to improve text classification tasks specifically for the Turkish language, a low-resource language with limited Natural Language Processing (NLP) resources. To address the common issue of class imbalance in real-world datasets, this study also implemented the KeNet data augmentation technique. The performance results showed that TurkRetNet considerably outperformed traditional models, e.g., Bidirectional Encoder Representations from Transformer for Turkish (BERTurk), and Convolutional BERT for Turkish (ConvBERTurk). The balanced dataset resulted in substantial improvements over the imbalanced dataset, with classification accuracy increasing by 6.06%, macro precision by 7.89%, macro recall by 9.52%, and macro F1-score by 8.86%. This research emphasises the efficacy of combining advanced neural architectures with effective data augmentation approaches that specifically target the distinct issues presented by low-resource languages. The combined application of TurkRetNet and KeNet set a new benchmark in Turkish text classification tasks. This study contributes to the advancement of NLP for under-resourced languages.
