Fixing paper assignments

  1. Please select all papers that belong to the same person.
  2. Indicate below which author they should be assigned to.
Provide a valid ORCID iD here. This will be used to match future papers to this author.
Provide the name of the school or the university where the author has received or will receive their highest degree (e.g., Ph.D. institution for researchers, or current affiliation for students). This will be used to form the new author page ID, if needed.

Enhancing NER by Harnessing Multiple Datasets with Conditional Variational Autoencoders
Taku Oi | Makoto Miwa
Proceedings of the 63rd Annual Meeting of the Association for Computational Linguistics (Volume 2: Short Papers)

We propose a novel method to integrate a Conditional Variational Autoencoder (CVAE) into a span-based Named Entity Recognition (NER) model to model the shared and unshared information among labels in multiple datasets and ease the training on the datasets. Experimental results using multiple biomedical datasets show the effectiveness of the proposed method, achieving improved performance on the BioRED dataset.
