A Joint Named-Entity Recognizer for Heterogeneous Tag-sets Using a Tag Hierarchy (P19-1)
Copied to clipboard
| Challenge: | Named-entity recognition (NER) has seen significant progress with the application of Neural Networks to the task. |
| Approach: | They propose to use a given tag hierarchy to jointly learn a neural network that shares its tagging layer among all tag-sets. |
| Outcome: | The proposed model outperforms models that combine independent models and multitasking approaches in a domain adaptation for named-entity recognition task. |

| Challenge: | Named Entity Recognition (NER) is an important step in de-identification (de-ID) of medical records, many of which are recorded conversations between a patient and a doctor. |
| Approach: | They propose to use Named Entity Recognition (NER) to detect audio spans with entity mentions in medical records and then use it to evaluate the results. |
| Outcome: | The proposed pipeline is based on a large labeled segment of the Switchboard and Fisher audio datasets and compares it with a benchmark. |
