Researchers have introduced PubMedCausal, a new corpus designed for causal relation extraction in biomedical text. This dataset, derived from PubMed abstracts, offers span-level annotations for 3,945 causal rows and 6,491 cause-effect pairs, enabling detailed evaluation of model capabilities. Benchmarks show that while biomedical encoders like PubMedBERT perform strongly in causal detection, generative models such as DeepSeek-R1-32B achieve competitive results in span-level extraction with few-shot prompting.
