Improving Temporal Relation Extraction with a Globally Acquired Statistical Resource (N18-1)
Copied to clipboard
| Challenge: | Existing temporal extraction systems that extract temporal relations can be improved by using a resource that provides prior knowledge of the temporal order that events usually follow. |
| Approach: | They propose to use a probabilistic knowledge base acquired in the news domain to extract temporal relations between events from the New York Times articles over a 20-year span. |
| Outcome: | The proposed system and resource are both publicly available. |
CogCompTime: A Tool for Understanding Time in Natural Language (D18-2)

| Challenge: | Existing systems that extract temporal information from text can be useful for natural language understanding. |
| Approach: | They propose a system that extracts temporal information from text and normalizes it to a standard format. |
| Outcome: | The proposed system achieves state-of-the-art performance and incorporates the most recent progress. |

Copied to clipboard
| Challenge: | a meta-framework for news events that extracts quantities from text is proposed . a previous work on news events focused on extracting event mentions, attributes, and relationships . |
| Approach: | They propose a meta-framework for solving the NLP problem of spatiotemporal quantity extraction . they demonstrate the framework is general and extensible, and shareable crowdsourcing pipeline and baseline models are used . |
| Outcome: | The proposed framework is general and extensible, the authors say . it can extract quantity from news streams, quickly respond to emergencies, investigate incidents . |
