Abstract:
This study presents a new strategy based on Natural Language Processing (NLP)
techniques for detecting and mitigating misogyny on social media. In this study a
dataset was constructed of 3.8 million instances of hate speech from various social
media networks that were collected meticulously. Advances in this research are
substantially hampered by the lack of a sizable Bengali dataset for the detection of
hate speech and sexism in Bengali language texts, making it difficult to effectively
identify and address these problems. To improve the representation of hate speech
in the dataset, an embedding model based on informal FastText is presented, which
captures the complex semantics of hate speech more accurately than other meth ods. This improved word embedding model is incorporated into a Bidirectional
Long Short-Term Memory (BiLSTM) architecture in order to identify contextual
dependencies and sequential patterns within hate speech comments. The model’s
layers are trained to encode and comprehend sequential information while tak ing both preceding and subsequent context into account, enabling it to better
comprehend remarks and their context. The proposed methodology is evaluated
exhaustively on a meticulously annotated dataset, allowing for a thorough anal ysis of its performance. Measurements of precision, recall, and F1-score are used
to evaluate the accuracy and effectiveness of hate speech detection. The results
demonstrate the framework’s superior performance and discrimination capabili ties, validating its capacity to accurately identify and categorize instances of hate
speech. In addition, this research contributes the largest dataset of hate speech in
the field and introduces a word embedding model that transcends existing tech niques. These findings substantially improve the understanding and detection of
hate speech on social media platforms, laying the groundwork for more effective
mechanisms to combat hate speech and promote safer online communities
