Textual Feature Extraction Using Ant Colony Optimization for Hate Speech Classification

نویسندگان

چکیده

Feature selection and feature extraction have always been of utmost importance owing to their capability remove redundant irrelevant features, reduce the vector space size, control computational time, improve performance for more accurate classification tasks, especially in text categorization. These engineering techniques can further be optimized using optimization algorithms. This paper proposes a similar framework by implementing one such algorithm, Ant Colony Optimization (ACO), incorporating different on textual numerical datasets four machine learning (ML) models: Logistic Regression (LR), K-Nearest Neighbor (KNN), Stochastic Gradient Descent (SGD), Random Forest (RF). The aim is show difference results achieved both with help comparative analysis. proposed assist enhancing model. research article considers text-based stroke prediction detecting hate speech, respectively. dataset prepared extracting tweets consisting positive, negative, neutral sentiments from Twitter API. A maximum improvement accuracy 10.07% observed TF-IDF technique application ACO. Besides, this study also highlights limitations data that inhibit models, justifying almost 18.43% compared data.
