| Challenge: | Social media data is often aggregated without regard to users in the Twitter populations of each community. |
| Approach: | They propose to use Twitter language to build community-level models using Twitter language aggregated by users. |
| Outcome: | The proposed method improves on four county-level tasks spanning demographic, health, and psychological outcomes over the standard approach of aggregating all tweets. |
Modeling Empathy and Distress in Reaction to News Stories (D18-1)
Copied to clipboard
| Challenge: | a recent work on empathy prediction has underestimated the complexity of the phenomenon and lacks a shared corpus. authors present a novel annotation methodology which reliably captures empathy assessments by the writer of a statement using multi-item scales. |
| Approach: | They propose a method which captures empathy assessments by the writer of a statement using multi-item scales. |
| Outcome: | The proposed method distinguishes between multiple forms of empathy, empathic concern, and personal distress, as recognized throughout psychology. |

| Challenge: | lexical features outperform syntactic features in expressing control in social media . authors communicate internal locus of control when they ascribe control to themselves . |
| Approach: | They examine the role of syntax and semantics in expressing users’ sense of control in annotated Facebook posts. |
| Outcome: | The proposed language outperforms syntactic features in identifying whether or not a user is in control of their circumstances. |
Learning Word Ratings for Empathy and Distress from Document-Level User Responses (2020.lrec-1)
Copied to clipboard
| Challenge: | Emotion analysis of text is increasing in popularity in NLP, however, manually creating lexica for psychological constructs such as empathy has proven difficult. |
| Approach: | They compare different approaches to learning word ratings from higher-level supervision and use a Mixed-Level Feed Forward Network to create the first-ever empathy lexicon. |
| Outcome: | The proposed model automatically creates empathy word ratings from document-level ratings. |
