| Challenge: | 3.1K reviews are manually annotated for aspect-based sentiment analysis (ABSA) ABSA is a fine-grained task that aims to identify the sentiment associated with each aspect or characteristic of a text. |
| Approach: | They propose a new Czech dataset for aspect-based sentiment analysis . the new dataset is built upon the older Czech dataset . authors provide 24M reviews without annotations suitable for unsupervised learning . |
| Outcome: | The proposed dataset is built upon the older dataset, but is specifically designed for more complex tasks. |

| Challenge: | Existing approaches to cross-lingual aspect-based sentiment analysis depend on translation tools. |
| Approach: | They propose a cross-lingual aspect-based sentiment analysis framework that leverages a large language model to generate pseudo-labelled data in target language. |
| Outcome: | The proposed approach outperforms translation-based approaches in six languages and five backbone models. |
