CantoMap: a Hong Kong Cantonese MapTask Corpus (2020.lrec-1)
Copied to clipboard
| Challenge: | a corpus of connected spoken Hong Kong Cantonese is constructed to study the phonology and semantics of the language. |
| Approach: | They propose to build a corpus of connected spoken Hong Kong Cantonese with phonemic transcription and controlled elicitation tasks. |
| Outcome: | The proposed corpus contains 768 minutes of recordings and transcripts of forty speakers. |

| Challenge: | lexical database for Hong Kong Cantonese offers phonological and orthographic information, frequency measures, and lexically neighborhood information for lexicals in HKC. |
| Approach: | They introduce a lexical database for Hong Kong Cantonese that offers phonological and orthographic information, frequency measures, and lexically neighborhood information for lexicals in HKC. |
| Outcome: | The proposed lexical database for Hong Kong Cantonese offers phonological and orthographic information, frequency measures, and lexically neighborhood information. |
Unveiling Identity Biases in Toxicity Detection : A Game-Focused Dataset and Reactivity Analysis Approach (2023.emnlp-industry)
Copied to clipboard
| Challenge: | Existing datasets focused on gender or racial biases are not designed for the gaming industry, a concern for models built for toxicity detection in videogames’ written chat. |
| Approach: | They propose to use reactivity analysis to highlight oversensitive terms using a language model developed by Ubisoft for toxicity detection on videogame’s written chat and Perspective API to generate a list of terms that trigger the models to varying degrees. |
| Outcome: | The proposed model can detect and amplify identity biases in annotated language models and is compared with a language model developed by Ubisoft for toxicity detection on videogames’ written chat and Perspective API. |
