The rise of the internet, particularly social media platforms, has led to exponential growth in online content creation. However, along with this growth comes the issue of hate speech—offensive or threatening speech targeting individuals based on characteristics such as ethnicity, religion, or sexual orientation. Hate speech detection models have become crucial in moderating online content and preventing the spread of harmful speech. One such innovative tool is SGHateCheck, developed by Assistant Professor Roy Lee and his team from the Singapore University of Technology and Design (SUTD).
Traditional evaluation methods using held-out test sets often fail to accurately assess hate speech detection models due to inherent biases within the datasets. To overcome this limitation, SGHateCheck was developed as an AI-powered tool specifically tailored to the linguistic and cultural context of Southeast Asia. This regional focus is essential because current hate speech detection models are mainly based on Western contexts and may not accurately capture the unique social dynamics and issues present in Southeast Asia.
Unlike previous tools like HateCheck and Multilingual HateCheck, SGHateCheck utilizes large language models (LLMs) to translate and paraphrase test cases into Singapore’s four main languages—English, Mandarin, Tamil, and Malay. Native annotators then refine these test cases to ensure cultural relevance and accuracy. This meticulous process results in over 11,000 annotated test cases that provide a nuanced platform for evaluating hate speech detection models. By incorporating regional linguistic features such as Singlish, SGHateCheck ensures that the tests are culturally sensitive and relevant to the Southeast Asian context.
The research team also found that LLMs trained on multilingual datasets show a more balanced performance in detecting hate speech across various languages compared to LLMs trained on monolingual datasets. This highlights the significance of including culturally diverse and multilingual training data when developing applications for multilingual regions like Southeast Asia. SGHateCheck’s focus on regional specificity and diverse training data sets it apart as a valuable tool for enhancing the detection and moderation of hate speech in online environments in these regions.
SGHateCheck is poised to make a significant impact in various online spaces such as social media platforms, online forums, news websites, and community platforms. Asst. Prof. Lee also plans to expand the tool to include other Southeast Asian languages like Thai and Vietnamese to cater to a wider audience. The development of SGHateCheck exemplifies SUTD’s commitment to integrating cutting-edge technology with thoughtful design principles to address real-world issues. By focusing on creating a culturally sensitive hate speech detection tool, the study underscores the importance of a human-centered approach in technological research and development.
SGHateCheck stands as a pioneering tool that not only advances the field of hate speech detection but also contributes to creating a more respectful and inclusive online environment in Southeast Asia. Its focus on regional specificity, cultural sensitivity, and multilingual capabilities positions it as a valuable asset in combating hate speech and promoting online safety in a diverse and multilingual region like Southeast Asia.
