In flat NER, entities never overlap. In nested NER, one mention can sit inside another. Standard sequence labeling gives each token only one tag, so it cannot represent nested structures, and earlier nested-NER systems often relied on pipelines or… 2. **[Dice Loss for Data-imbalanced NLP Tasks](https://md.research.elamur.ai/free/en/papers/li-2020-dice-loss-data-imbalanced-nlp/)** *(2020 · 734 citations)* Many NLP tasks have far more negative examples than positive ones. In NER, most tokens carry the background tag O. In MRC, only the start and end tokens of an answer count as positive. Standard cross-entropy weights every instance equally, so it rewards accuracy, while these tasks are judged by F1. The large number… ## Also in our library 2 more works of theirs are in our library without a page here yet; they will appear as we publish them. ## Co-authors here 4 co-authors with a page, the most papers together first. - [Fei Wu](https://md.research.elamur.ai/free/en/authors/fei-wu/) ×2 - [Jiwei Li](https://md.research.elamur.ai/free/en/authors/jiwei-li/) ×2 - [Xiaoya Li](https://md.research.elamur.ai/free/en/authors/xiaoya-li/) ×2 - [Xiaofei Sun](https://md.research.elamur.ai/free/en/authors/xiaofei-sun/) ## Cited by Papers of our library cite their works 295 times (of the 140 884 papers whose bibliographies we read); [19 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/yuxian-meng/cited-by/).
