| Challenge: | Large-scale pretraining models have been shown to learn effective linguistic representations for many NLP tasks, but there are many real-world contextual aspects of language that current approaches do not capture. |
| Approach: | They propose to integrate speaker social context into the learned representations of large-scale language models by using graph representation learning algorithms and primed language model pretraining with these social context representations. |
| Outcome: | The proposed approach improves on geographically sensitive language modeling tasks by more than 100% relative lift on MRR compared to baselines. |
