The rapid advancement of neural text systems, particularly large-scale pretrained language models, has transformed natural language processing (NLP) across diverse applications. However, their dependence on vast datasets raises critical concerns regarding vulnerability to data contamination, especially in limited-data environments. This paper investigates the susceptibility of neural text systems to various forms of data poisoning and contamination under constrained data conditions, with a focus on low-resource linguistic contexts. Drawing upon interdisciplinary perspectives from machine learning security, data ethics, and computational linguistics, the study examines how data scarcity amplifies risks associated with adversarial manipulation, bias propagation, and representational distortion.

The research synthesizes existing frameworks of data poisoning attacks, including clean-label, backdoor, and federated poisoning mechanisms, while situating them within the structural limitations of low-resource datasets. Theoretical grounding is established through analyses of model generalization, transfer learning dynamics, and statistical dependency structures inherent in neural architectures. Furthermore, the study explores how limited corpus diversity intensifies model sensitivity to corrupted inputs, leading to systemic degradation in performance, fairness, and robustness.

A conceptual model is developed to illustrate the interaction between dataset quality, model architecture, and adversarial interference. Through analytical evaluation, the study demonstrates that neural text systems operating in low-resource environments exhibit disproportionately higher vulnerability to contamination due to overfitting tendencies, reliance on pretrained representations, and insufficient noise filtering mechanisms. Additionally, the research highlights the role of socio-technical factors, including data curation practices and algorithmic governance, in shaping model resilience.

The findings underscore the necessity for robust data validation protocols, secure training pipelines, and adaptive learning strategies tailored to constrained environments. The paper contributes to ongoing discourse on trustworthy AI by identifying critical vulnerabilities in contemporary NLP systems and proposing strategic directions for enhancing resilience against data contamination. Ultimately, it emphasizes that safeguarding neural text systems requires not only technical innovation but also ethical and institutional interventions.
