Event Causality Extraction with Event Argument Correlations (2022.coling-1)
Copied to clipboard
| Challenge: | Event Causality Identification (ECI) ignores crucial event structure and cause-effect component information, making it struggle for downstream applications. |
| Approach: | They propose a task to extract event causality pairs with their structured event information from plain text. |
| Outcome: | The proposed method captures the intra- and inter-event argument correlations for ECE and provides several future directions. |
FITAnnotator: A Flexible and Intelligent Text Annotation System (2021.naacl-demos)
Copied to clipboard
| Challenge: | In this paper, we introduce FITAnnotator, a generic web-based tool for efficient text annotation. |
| Approach: | They propose a generic web-based tool for efficient text annotation. |
| Outcome: | The proposed tool is based on a fully modular architecture and provides three kinds of interfaces to annotate instances, evaluate annotation quality and manage the annotation task for annotators, reviewers and managers. |
Enhancing Joint Multiple Intent Detection and Slot Filling with Global Intent-Slot Co-occurrence (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing joint models only use training procedure to determine the implicit correlation between intents and slots. |
| Approach: | They propose to make full use of the statistical co-occurrence frequency between intents and slots as prior knowledge to enhance joint multiple intent detection and slot filling. |
| Outcome: | The proposed model outperforms state-of-the-art models on two public multi-intent datasets. |
