Papers with procedural text comprehension
Reasoning about Actions and State Changes by Injecting Commonsense Knowledge (D18-1)
Copied to clipboard
| Challenge: | Recent work has shown impressive progress in comprehending procedural text, but their predictions can be inconsistent or highly improbable. |
| Approach: | They propose to incorporate global constraints and bias reading with corpora-based preferences to improve the predicted effects of actions in a paragraph. |
| Outcome: | The proposed model significantly outperforms earlier models on a benchmark dataset for procedural text comprehension (+8% relative gain) it avoids nonsensical predictions that earlier models make, and it is more robust than previous models. |
Everything Happens for a Reason: Discovering the Purpose of Actions in Procedural Text (D19-1)
Copied to clipboard
| Challenge: | XPAD is a new model that predicts actions' effects and their dependencies based on background knowledge . previous work on extracting sequences of actions from text has focused on identifying why they are the way they are . |
| Approach: | They propose a new model that biases effect predictions towards those that explain more of the actions in the paragraph and are more plausible with respect to background knowledge. |
| Outcome: | The proposed model outperforms existing systems on explaining actions by predicting dependencies while maintaining the performance on the original task in ProPara. |
Understanding Procedural Text using Interactive Entity Networks (2020.emnlp-main)
Copied to clipboard
| Challenge: | Recent efforts to track multiple entities in a procedural text treat each entity separately . e.g., scientific articles, instruction books, recipes, often contain multiple entities involved . |
| Approach: | They propose a recurrent network with memory equipped cells for state tracking . they maintain different attention matrices through specific memories to model different types of entity interactions . |
| Outcome: | The proposed model outperforms state-of-the-art models on a benchmark dataset. |
