SweClinEval: A Benchmark for Swedish Clinical Natural Language Processing

Abstract

The lack of benchmarks in certain domains and for certain languages makes it difficult to track progress regarding the state-of-the-art of NLP in those areas, potentially impeding progress in important, specialized domains. Here, we introduce the first Swedish benchmark for clinical NLP: _SweClinEval_. The first iteration of the benchmark consists of six clinical NLP tasks, encompassing both document-level classification and named entity recognition tasks, with real clinical data. We evaluate nine different encoder models, both Swedish and multilingual. The results show that domain-adapted models outperform generic models on sequence-level classification tasks, while certain larger generic models outperform the clinical models on named entity recognition tasks. We describe how the benchmark can be managed despite limited possibilities to share sensitive clinical data, and discuss plans for extending the benchmark in future iterations.
