Multi-domain text classification via linguistic and semantic feature integration
Text classification is widely used in tasks such as sentiment analysis, spam detection, and hate speechdetection, but performance often suffers when models rely on only linguistic features or semantic embeddings.Single-representation methods struggle to capture both syntactic structure and deep semantic meaning, limitingrobustness and generalization across tasks. This study proposes a hybrid feature fusion framework that combinesinterpretable linguistic features with semantic embeddings from Doc2Vec and transformer-based models. Theapproach is evaluated on five benchmark datasets covering fake news detection, Bloom’s taxonomy classification, andhate speech detection. Experiments with multiple classifiers show that the fused features consistently outperformsingle-feature baselines. The best results, using a BERT-based fusion approach, achieve accuracies of 81% for fakenews detection, 67% for Bloom’s taxonomy classification, and 72% for hate speech detection, with improved precision, recall, and F1-score. Overall, the results demonstrate that integrating linguistic and semantic featuresprovides a robust, domain-agnostic solution for improved text classification.
