Neural Language Modeling for Named Entity Recognition (2020.coling-main)
Copied to clipboard
| Challenge: | Experimental results show that named entity recognition systems are faster and more flexible for the size of the corpus. |
| Approach: | They propose to use a neural language model as an alternative to the conditional random field layer for named entity recognition. |
| Outcome: | The proposed system has a significant speed advantage with a marginal performance degradation. |
Investigation on Data Adaptation Techniques for Neural Named Entity Recognition (2021.acl-srw)
Copied to clipboard
| Challenge: | Existing methods for named entity recognition use only a limited number of samples . data augmentation and selftraining are popular methods to generate additional synthetic data . |
| Approach: | They investigate the impact of data augmentation and data augmented on named entity recognition tasks. |
| Outcome: | The proposed methods improve the performance of three named entity recognition tasks. |
Controllable Factuality in Document-Grounded Dialog Systems Using a Noisy Channel Model (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Recent document-grounded dialog systems have seen an increase in popularity. |
| Approach: | They propose a model for document-grounded response generation in dialog that is decomposed into two components according to Bayes’ theorem and propose different approximate decoding schemes. |
| Outcome: | The proposed model is more factual in terms of automatic factuality metrics than the baseline model and can be combined with a recently proposed method to control factuity in grounded dialog, CTRL. |
