Not only is it complicated, but it has also become a pressing necessity, considering how social media has become an integral part of adolescents’ lives and how serious the impacts of cyberbullying and online harassment can be, particularly among teenagers. This paper contains a systematic literature review of modern strategies, machine learning methods, and technical means for detecting cyberbullying and the aggressive command of an individual in the information space of the Internet. We undertake an in-depth review of 13 papers from four scientific databases. The article provides an overview of scientific literature to analyze the problem of cyberbullying detection from the point of view of machine learning and natural language processing. In this review, we consider a cyberbullying detection framework on social media platforms, which includes data collection, data processing, feature selection, feature extraction, and the application of machine learning to classify whether texts contain cyberbullying or not. This article seeks to guide future research on this topic toward a more consistent perspective with the phenomenon’s description and depiction, allowing future solutions to be more practical and effective.

This study presents a new intelligent system based on deep learning methods for the automatic detection of hate speech in the Kazakh language. Particular attention is paid to the specific nature of Kazakh as a resource-poor language, where the limited linguistic data poses significant challenges in building reliable models. A multilingual data corpus covering a wide range of speech contexts was generated and preprocessed using various online sources-social media, forums, and news portals. To improve efficiency and generalization performance, a hybrid architecture was proposed, including convolutional neural networks (CNNs), bidirectional long short-term memories (BiLSTMs), and Transformer attention mechanisms. An evaluation using precision, recall, F1-criterion, and accuracy metrics demonstrated the superiority of the proposed model over traditional machine learning algorithms. The results of the study make a significant contribution to the development of automatic content moderation systems and promote the creation of a safer, inclusive, and linguistically sensitive digital space for Kazakh-speaking users.

Correct segmentation of brain tumors using multimodal magnetic resonance imaging (MRI) is critical for quantitative tumor evaluation, therapy planning and disease monitoring. However, the variability of tumor size, shape, location and appearance among MRI modalities poses a challenge for automatic segmentation. Heterogeneous structure of brain tumors and uneven boundaries of different subregions of a tumor also often impede the effectiveness of traditional segmentation methods. Hence, there is a need for strong approaches that can model local spatial features and long-range contextual dependencies. In this paper, we propose a deformable attention-guided Transformer architecture for multimodal brain tumor segmentation. The framework uses complementary information from T1, T1c, T2 and FLAIR MRI modalities and fuses multi-scale feature extraction, adaptive query refinement, deformable attention and skip connections to improve heterogeneous tumor region representation. We performed experiments on the dataset from the brain tumor image segmentation benchmark (BRATS) multimodal. The model was assessed in terms of Dice coefficient, Precision, Recall and F1-score on Whole Tumor (WT), Tumor Core (TC) and Enhancing Tumor (ET) regions. The suggested model attained Dice scores of 95.8%, 90.7%, and 86.1% for WT, TC and ET, respectively, while the average Dice score was 90.9%. Ablation analysis further highlighted the contribution of deformable attention, query refinement, skip connections and multimodal feature integration to the segmentation performance. The model also showed a good trade-off between segmentation accuracy and computational efficiency, which suggests the possible use of this approach in automated MRI processing workflows. The experimental results illustrate the potential of the proposed framework for accurate and robust multimodal MRI based brain tumor segmentation.
