CONSCENDI: A Contrastive and Scenario-Guided Distillation Approach to Guardrail Models for Virtual Assistants (2024.naacl-long)
Copied to clipboard
| Challenge: | A major challenge in deploying LLM-based virtual conversational assistants in real world settings is ensuring they operate within what is admissible for the task. |
| Approach: | They propose to use large language models (LLMs) to generate training data with two key LLM components: scenario-augmented generation and contrastive training examples. |
| Outcome: | The proposed model improves over baselines in multiple dialogue domains. |
Clinical Concept Linking with Contextualized Neural Representations (2020.acl-main)
Copied to clipboard
| Challenge: | Entity linking systems rely on three sources of information: 1) similarity between mention string and entity name; 2) similarity of context of document to entity; 3) broader information about knowledge base; 4) contextual information; 5) semantic information; and 6) semantic information. |
| Approach: | They propose an approach to linking medical concepts to a medical concept ontology that leverages recent work in contextualized neural models. |
| Outcome: | The proposed approach outperforms a baseline approach and provides better initialization for the ranker. |
Cross-Lingual Transfer in Zero-Shot Cross-Language Entity Linking (2021.findings-acl)
Copied to clipboard
| Challenge: | Existing work on cross-language entity linking grounds mentions written in multiple languages to a monolingual knowledge base is lacking. |
| Approach: | They propose a task that uses multilingual BERT representations of both the mention and context as input and explore zero-shot language transfer. |
| Outcome: | The proposed model performs well in both monolingual and multilingual settings. |
