Nested named entity recognition in traditional Chinese medicine electronic medical records via dual-granularity feature augmentation and span classification.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Named Entity Recognition (NER) plays a crucial role in extracting important information such as treatment methods, symptoms, and herbal prescriptions from Traditional Chinese Medicine (TCM) electronic medical records. However, existing NER methods often struggle with the complexity and variability of TCM language, especially when dealing with overlapping or nested entities. To address these issues, we propose DG-SpanTCM, a novel framework that enhances character-level text understanding using a pre-trained language model and improves entity recognition through lexical-semantic features and robust training strategies. Our method also incorporates techniques to handle label imbalance and better identify complex entity structures. Experiments on a real-world TCM dataset show that DG-SpanTCM achieves superior performance, improving the F1-score over strong baseline models. These findings highlight the potential of DG-SpanTCM in advancing automated information extraction for TCM texts.
