Towards General Natural Language Understanding with Probabilistic Worldbuilding (2022.tacl-1)
Copied to clipboard
| Challenge: | Probabilistic worldbuilding model is a Bayesian model of semantic parsing and reasoning . large-scale language models are domain-general, despite training on text from virtually every domain . |
| Approach: | They propose a Bayesian probabilistic worldbuilding model that parses and abduces sentences . they use a dataset to test their method against heuristics and to generate a probability model . |
| Outcome: | The proposed model outperforms baselines on two out-of-domain question-answering datasets. |
