Share First, Save Later: Performance of Self through Snapchat Stories

論文URL: http://dl.acm.org/citation.cfm?doid=3025453.3025771

論文アブストラクト: As the third most popular social network among millennials, Snapchat is well known for its picture and video messaging system that deletes content after it is viewed. However, the Stories feature of Snapchat offers a different perspective of ephemeral content sharing, with pictures and videos that are available for friends to watch an unlimited number of times for 24 hours. We conduct-ed an in-depth qualitative investigation by interviewing 18 participants and reviewing 14 days of their Stories posts. We identify five themes focused on how participants perceive and use the Stories feature, and apply a Goffmanesque metaphor to our analysis. We relate the Stories medium to other research on self-presentation and identity curation in social media.

Situated Anonymity: Impacts of Anonymity, Ephemerality, and Hyper-Locality on Social Media

論文URL: http://dl.acm.org/citation.cfm?doid=3025453.3025682

論文アブストラクト: Anonymity, ephemerality, and hyper-locality are an uncommon set of features in the design of online communities. However, these features were key to Yik Yak's initial success and popularity. In an interview-based study, we found that these three features deeply affected the identity of the community as a whole, the patterns of use, and the ways users committed to this community. We conducted interviews with 18 Yik Yak users on an urban American university campus and found that these three focal design features contributed to casual commitment, transitory use, and emergent community identity. We describe situated anonymity, which is the result of anonymity, ephemerality, and hyper-locality coexisting as focal design features of an online community. This work extends our understanding of use and identity-versus-bond based commitment, which has implications for the design and study of other atypical online communities.

Relational Distancing and Termination between Online Friends: An Application of the Investment Model

論文URL: http://dl.acm.org/citation.cfm?doid=3025453.3026026

論文アブストラクト: This research examined the relational maintenance versus termination of online friendships in Facebook. Guided by Rusbult's [33] investment model (IM), the study constructed a model to examine 55 matched pairs of Facebook friends consisting of one "primary user" and one "annoyer." Results indicated that primary users' judgments of relational satisfaction with annoyers were influenced by annoyers' narcissistic personality and their overall propensity for posting overly self-focused content. Commitment affected primary users' use of both passive "unfollowing" and active "unfriending" in response to annoyers' behavior. Decisions to maintain or terminate online friendships are related to judgments and actions of both partners. Overall, these results emphasize the dyadic nature of relational maintenance and termination processes in online environments, and the importance of studying them as such.

Enhancing Personal Informatics Through Social Sensemaking

論文URL: http://dl.acm.org/citation.cfm?doid=3025453.3025804

論文アブストラクト: Personal informatics practices are increasingly common, with a range of consumer technologies available to support, largely individual, interactions with data (e.g., performance measurement and activity/health monitoring). In this paper, we explore the concept of social sensemaking. In contrast to high-level statistics, we posit that social networking and reciprocal sharing of fine-grained self-tracker data can provide valuable context for individuals in making sense of their data. We present the design of an online platform called Citizense Makers (CM), which facilitates group sharing, annotating and discussion of self-tracker data. In a field trial of CM, we explore design issues around willingness to share data reciprocally; the importance of familiarity between individuals; and understandings of common activities in contextualising one's own data.

Sizing Up the Troll: A Quantitative Characterization of Moderator-Identified Trolling in an Online Forum

論文URL: http://dl.acm.org/citation.cfm?doid=3025453.3026007

論文アブストラクト: A few troublemakers often spoil online environments for everyone else. An extremely disruptive type of abuser is the troll, whose malicious activities are relatively non-obvious, and thus difficult to detect and contain -- particularly by automated systems. A growing corpus of qualitative research focuses on trolling, and differentiates it from other forms of abuse; however, its findings are not directly actionable into automated systems. On the other hand, quantitative research uses definitions of "troll" that mostly fail to capture what moderators and users consider trolling. We address this gap by giving a quantitative analysis of posts, conversations, and users, specifically sanctioned for trolling in an online forum. Although trolls (unlike most other abusers) hardly stand out in a conversation e.g. in terms of vocabulary, textit{how} they interact, rather than textit{what} they contribute, provides cues of their malicious intent.
