Crises such as the COVID-19 pandemic continuously threaten our world and emotionally affect billions of people worldwide in distinct ways. Understanding the triggers leading to people’s emotions is of crucial importance. Social media posts can be a good source of such analysis, yet these texts tend to be charged with multiple emotions, with triggers scattering across multiple sentences. This paper takes a novel angle, namely, emotion detection and trigger summarization, aiming to both detect perceived emotions in text, and summarize events and their appraisals that trigger each emotion. To support this goal, we introduce CovidET (Emotions and their Triggers during Covid-19), a dataset of ~1,900 English Reddit posts related to COVID-19, which contains manual annotations of perceived emotions and abstractive summaries of their triggers described in the post. We develop strong baselines to jointly detect emotions and summarize emotion triggers. Our analyses show that CovidET presents new challenges in emotion-specific summarization, as well as multi-emotion detection in long social media posts.

Understanding the Semantics of Narratives of Interpersonal Violence through Reader Annotations and Physiological Reactions
Interpersonal violence (IPV) is a prominent sociological problem that affects people of all demographic backgrounds. By analyzing how readers interpret, perceive, and react to experiences narrated in social media posts, we explore an understudied source for discourse about abuse. We asked readers to annotate Reddit posts about relationships with vs. without IPV for stakeholder roles and emotion, while measuring their galvanic skin response (GSR), pulse, and facial expression. We map annotations to coreference resolution output to obtain a labeled coreference chain for stakeholders in texts, and apply automated semantic role labeling for analyzing IPV discourse. Findings provide insights into how readers process roles and emotion in narratives. For example, abusers tend to be linked with violent actions and certain affect states. We train classifiers to predict stakeholder categories of coreference chains. We also find that subjects' GSR noticeably changed for IPV texts, suggesting that co-collected measurement-based data about annotators can be used to support text annotation.

Coreference choices are influenced by multiple factors, including information structural categories such as topic and focus. These information structural categories can be indicated by intonation, yet few studies have investigated how intonation affects subsequent choices for coreference. Using a story continuation experiment with aurally presented stimuli, we show that the location of contrastive focus in Mainstream American English significantly affects the preferred referent for the subject of the next sentence in a short discourse.more » « less

Research suggests that Indigenous girls, women, and LGBTQ+ Two-Spirit people experience disproportionately high rates of intimate partner violence (IPV), but there is a dearth of research on IPV among Indigenous college students. Therefore, the current study sought to explore rates of IPV victimization and perpetration among Indigenous college students, as well as correlates including depressive and anxious symptoms, emotion dysregulation, on-campus social support, and hazardous drinking. Participants were 230 undergraduate students who identified as American Indian/Alaska Native attending 20 medium- and large-sized universities across the contiguous U.S. Results indicated that 28.9% of Indigenous students reported any type of IPV victimization in the past 6 months (psychological: 24.5%; physical: 9.1%; sexual: 9.8%; coercive control: 12.4%). Further, 18.3% of Indigenous students reported any type of IPV perpetration in the past 6 months (psychological: 16.9%; physical: 4.5%; sexual: 2.6%; coercive control: 7.1%). Anxious and depressive symptoms were related to many forms of IPV victimization; emotion dysregulation was related to all forms of IPV victimization and sexual IPV perpetration; and hazardous drinking was related to most forms of IPV victimization and perpetration. These findings underscore the alarmingly high rates of IPV among Indigenous college students as well as the potential deleterious effects of IPV victimization on psychological functioning, as well as the need to concurrently address hazardous alcohol use in IPV prevention and response efforts.more » « less

Budak, Ceren; Cha, Meeyoung; Quercia, Daniele; Xie, Lexing (Ed.)Despite the influence that image-based communication has on online discourse, the role played by images in disinformation is still not well understood. In this paper, we present the first large-scale study of fauxtography, analyzing the use of manipulated or misleading images in news discussion on online communities. First, we develop a computational pipeline geared to detect fauxtography, and identify over 61k instances of fauxtography discussed on Twitter, 4chan, and Reddit. Then, we study how posting fauxtography affects engagement of posts on social media, finding that posts containing it receive more interactions in the form of re-shares, likes, and comments. Finally, we show that fauxtography images are often turned into memes by Web communities. Our findings show that effective mitigation against disinformation need to take images into account, and highlight a number of challenges in dealing with image-based disinformation.more » « less

Social media companies wield power over their users through design, policy, and through their participation in public discourse. We set out to understand how companies leverage public relations to influence expectations of privacy and privacy-related norms. To interrogate the discourse productions of companies in relation to privacy, we examine the blogs associated with three major social media platforms: Facebook, Instagram (both owned by Facebook Inc.), and Snapchat. We analyze privacy-related posts using critical discourse analysis to demonstrate how these powerful entities construct narratives about users and their privacy expectations. We find that each of these platforms often make use of discourse about "vulnerable" identities to invoke relations of power, while at the same time, advancing interpretations and values that favor data capitalism. Finally, we discuss how these public narratives might influence the construction of users' own interpretations of appropriate privacy norms and conceptions of self. We contend that expectations of privacy and social norms are not simply artifacts of users' own needs and desires, but co-constructions that reflect the influence of social media companies themselves.more » « less
