We present NusaCrowd, a collaborative initiative to collect and unify existing resources for Indonesian languages, including opening access to previously non-public resources. Through this initiative, we have brought together 137 datasets and 118 standardized data loaders. The quality of the datasets has been assessed manually and automatically, and their value is demonstrated through multiple experiments.NusaCrowd’s data collection enables the creation of the first zero-shot benchmarks for natural language understanding and generation in Indonesian and the local languages of Indonesia. Furthermore, NusaCrowd brings the creation of the first multilingual automatic speech recognition benchmark in Indonesian and the local languages of Indonesia. Our work strives to advance natural language processing (NLP) research for languages that are under-represented despite being widely spoken.

This paper presents our findings in the ML-ESG-2 task, which focused on classifying a news snippet of various languages as “Risk” or “Opportunity” in the ESG (Environmental, Social, and Governance) context. We experimented with data augmentation and translation facilitated by Large Language Models (LLM). We found that augmenting the English dataset did not help to improve the performance. By fine-tuning RoBERTa models with the original data, we achieved the top position for the English and second place for the French task. In contrast, we could achieve comparable results on the French dataset by solely using the English translation, securing the third position for the French task with only marginal F1 differences to the second-place model.
