| Challenge: | Automating technical support is a task of providing answers to complex problems . traditional approaches to this task rely on information retrieval and are keyword based . |
| Approach: | They propose a semantic parsing approach that uses grammatical structure to extract technical questions' attributes as a baseline and a CRF-based model that can improve performance in the presence of annotated data. |
| Outcome: | The proposed model outperforms retrieval baselines in annotated data for training. |

| Challenge: | Current medical question answering systems have difficulty processing long, detailed and informally worded questions . a growing number of approaches attempt to enhance the processing of consumer health questions - or medical question understanding . |
| Approach: | They propose a medical question understanding and answering system with knowledge grounding and semantic self-supervision that matches a user question with a trusted medical knowledge base and retrieves a fixed number of relevant sentences from the corresponding answer document. |
| Outcome: | The proposed system retrieves more relevant answers while achieving 20 times faster. |
Parsing All: Syntax and Semantics, Dependencies and Spans (2020.findings-emnlp)
Copied to clipboard
| Challenge: | Syntactic and semantic structures are key linguistic contextual clues, but few studies have explored how they can be used to improve syntactical parsing. |
| Approach: | They propose a syntactic and semantic parsing model which integrates syntaktic information in the encoder of neural network and benefits from two representation formalisms in a uniform way. |
| Outcome: | The proposed model achieves state-of-the-art or competitive results on both span and dependency representations and on Penn Treebank. |
