bgGLUE: A Bulgarian General Language Understanding Evaluation Benchmark
This provides a standardized evaluation framework for Bulgarian language models, addressing a gap for this specific language community.
The authors introduced bgGLUE, a Bulgarian language understanding benchmark covering nine NLU tasks, and conducted the first systematic evaluation of pre-trained language models for Bulgarian, showing strong performance on sequence labeling tasks but significant room for improvement in complex reasoning tasks.
We present bgGLUE(Bulgarian General Language Understanding Evaluation), a benchmark for evaluating language models on Natural Language Understanding (NLU) tasks in Bulgarian. Our benchmark includes NLU tasks targeting a variety of NLP problems (e.g., natural language inference, fact-checking, named entity recognition, sentiment analysis, question answering, etc.) and machine learning tasks (sequence labeling, document-level classification, and regression). We run the first systematic evaluation of pre-trained language models for Bulgarian, comparing and contrasting results across the nine tasks in the benchmark. The evaluation results show strong performance on sequence labeling tasks, but there is a lot of room for improvement for tasks that require more complex reasoning. We make bgGLUE publicly available together with the fine-tuning and the evaluation code, as well as a public leaderboard at https://bgglue.github.io/, and we hope that it will enable further advancements in developing NLU models for Bulgarian.
