| Challenge: | Using dialog acts to study decision-making in large distributed organizations is challenging due to the size and distributed nature of such groups. |
| Approach: | They propose a set of dialog acts for the study of decision-making mechanisms in large distributed organizations. |
| Outcome: | The proposed dataset can be used to better understand decision-making in large distributed organizations. |

| Challenge: | Social science and psycholinguistic research have shown that power and status affect how people use language in a range of domains. |
| Approach: | They propose to use lexical categories and BERT to predict levels of influence in an online community and identify key linguistic differences between people before and after becoming influential. |
| Outcome: | The results show that participants' levels of influence can be predicted from their email text, and identify key differences in language use for the same person before and after becoming influential. |

| Challenge: | state of the art reviewer recommendation systems still have relatively high error rates . |
| Approach: | They propose to use a large language model to improve on SotA, but not a cure-all . they first create a new dataset and introduce LLMs with prompting to evaluate their performance. |
| Outcome: | The proposed approach improves on SotA but not cure-all, the authors argue . they show that the proposed approach can be extended to many related tasks . |
