A Span-Based Model for Joint Overlapped and Discontinuous Named Entity Recognition [PDF]
Annual Meeting of the Association for Computational Linguistics, 2021 Research on overlapped and discontinuous named entity recognition (NER) has received increasing attention. The majority of previous work focuses on either overlapped or discontinuous entities.

Adaptive Attention Span in Transformers [PDF]
Annual Meeting of the Association for Computational Linguistics, 2019 We propose a novel self-attention mechanism that can learn its optimal attention span. This allows us to extend significantly the maximum context size used in Transformer, while maintaining control over their memory footprint and computational time.

Few-Shot Question Answering by Pretraining Span Selection [PDF]
Annual Meeting of the Association for Computational Linguistics, 2021 In several question answering benchmarks, pretrained models have reached human parity through fine-tuning on an order of 100,000 annotated questions and answers.

Coreference Resolution without Span Representations [PDF]
Annual Meeting of the Association for Computational Linguistics, 2021 The introduction of pretrained language models has reduced many complex task-specific NLP models to simple lightweight layers. An exception to this trend is coreference resolution, where a sophisticated task-specific model is appended to a pretrained ...

The Stability and Change of Loneliness Across the Life Span: A Meta-Analysis of Longitudinal Studies
Personality and Social Psychology Review, 2019 Individuals experience loneliness when they perceive a deficiency in the quality or quantity of their social relationships. In the present meta-analysis, we compiled data from 75 longitudinal studies conducted in Asia, Australia, Europe, and North ...

Telomere shortening rate predicts species life span
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance The exact causes of aging are still not understood, and it is unclear why some species live less than 1 d, while others can live more than 400 y.

Open-Domain Targeted Sentiment Analysis via Span-Based Extraction and Classification [PDF]
Annual Meeting of the Association for Computational Linguistics, 2019 Open-domain targeted sentiment analysis aims to detect opinion targets along with their sentiment polarities from a sentence. Prior work typically formulates this task as a sequence tagging problem. However, such formulation suffers from problems such as

A Span-Extraction Dataset for Chinese Machine Reading Comprehension [PDF]
EMNLP-IJCNLP, 2019 Machine Reading Comprehension (MRC) has become enormously popular recently and has attracted a lot of attention. However, the existing reading comprehension datasets are mostly in English. In this paper, we introduce a Span-Extraction dataset for Chinese

Dynamics of life expectancy and life span equality
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Why life expectancy and life span equality have increased together is a question of scientific interest. Both measures are calculated for a calendar year and might not describe a cohort’s actual life course.

CorefQA: Coreference Resolution as Query-based Span Prediction [PDF]
Annual Meeting of the Association for Computational Linguistics, 2019 In this paper, we present CorefQA, an accurate and extensible approach for the coreference resolution task. We formulate the problem as a span prediction task, like in question answering: A query is generated for each candidate mention using its ...
