Modeling Complex Event Scenarios via Simple Entity-focused Questions (2023.eacl-main)
Copied to clipboard
| Challenge: | Event schemas describe a sequence of events in a particular context, but they are difficult to model with standard event language models. |
| Approach: | They propose a question-guided generation framework that generates events as answers to questions about participants. |
| Outcome: | The proposed framework provides better coverage of participants, diverse events within a domain, comparable perplexities for modeling event sequences, and more effective control for interactive schema generation. |

POQue: Asking Participant-specific Outcome Questions for a Deeper Understanding of Complex Events (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing language models lag behind human performance in subtle ways in understanding complex situations, e.g., if the Argentine government yields to [IMF] pressure to rescind emergency legislation meant to protect ordinary families like the Brofmans. |
| Approach: | They propose to pre-identify a participant in a complex event and annotate their volitional engagement in causing the situation. |
| Outcome: | The proposed model can be used to infer the collective impact of salient events that make up a complex event, annotate volitional engagement of participants, and ground the outcome in state changes of the participants. |

| Challenge: | Complex news events require swift responses from government and society, authors say . relying on historical events to project the future is insufficient, they say - a simulator for complex news events is needed . |
| Approach: | They propose a controllable complex news event simulator guided by event schema and user-provided assumptions . they incorporate a geo-diverse commonsense and cultural norm-aware knowledge enhancement component . |
| Outcome: | The proposed simulator achieves higher coherence and appropriateness than existing models. |
