The prevalence of social media platforms has increased exponentially in recent years, providing users with the ability to share content, opinions, and ideas online. However, the unrestricted nature of social media has also led to the proliferation of hate speech – offensive or threatening language targeting individuals based on characteristics such as ethnicity, religion, and sexual orientation.
Hate speech detection models play a crucial role in moderating online content and reducing the dissemination of harmful speech, particularly on social media platforms. These computational systems are designed to identify and categorize online comments as hate speech, thereby enabling platforms to take appropriate action to address such content.
Traditional evaluation methods for hate speech detection models often rely on held-out test sets to assess performance. However, these methods can be flawed due to inherent biases within the datasets. As a result, there is a need for more robust evaluation tools that can accurately capture the complexity and diversity of hate speech in real-world scenarios.
Prof. Roy Lee and his team at the Singapore University of Technology and Design (SUTD) have developed SGHateCheck, an AI-powered tool specifically designed to detect hate speech in the linguistic and cultural context of Singapore and Southeast Asia. By building upon existing frameworks like HateCheck and Multilingual HateCheck, SGHateCheck offers a more nuanced approach to evaluating hate speech detection models.
Unlike generic hate speech detection models, SGHateCheck incorporates the linguistic diversity of Singapore by using large language models to translate and paraphrase test cases in English, Mandarin, Tamil, and Malay. This regional specificity ensures that the tool is culturally relevant and accurate, with over 11,000 meticulously annotated test cases to evaluate hate speech detection models.
The team found that language models trained on multilingual datasets outperform those trained on monolingual data sets when it comes to detecting hate speech. This highlights the importance of including culturally diverse training data in order to accurately detect hate speech across various languages and cultural contexts. SGHateCheck’s multilingual approach enhances its performance in identifying hate speech in online environments.
Asst. Prof. Lee plans to implement SGHateCheck in various online platforms, including social media, forums, news websites, and community platforms. The tool will provide valuable support in detecting and moderating hate speech, fostering a more respectful and inclusive online space. Additionally, there are plans to expand SGHateCheck to include other Southeast Asian languages such as Thai and Vietnamese, further enhancing its reach and impact in the region.
SGHateCheck exemplifies SUTD’s commitment to integrating cutting-edge technology with cultural sensitivity to address real-world issues. By focusing on local languages and social dynamics, the tool not only showcases technological sophistication but also highlights the importance of a human-centered approach in technological research and development. Asst. Prof. Lee’s work underscores the significance of designing hate speech detection tools that are not only effective but also culturally sensitive, paving the way for more inclusive online environments.
