It explores issues related to public sharing of personal stories, the ethical obligations of researchers who use web data, and the changing nature of online privacy. The film was conceived by Andrew Gordon and Christopher Wienberg at the University of Southern California, whose research involves the collection of millions of personal stories posted to internet weblogs. In analyzing their data, these researchers discovered an unusual population of extremely prolific bloggers, people who post personal stories about their daily lives everyday over the course of many years. They posed three questions about this population: 1. What motivates these people to post so frequently and publicly about their personal life? 2. To what degree do these people embellish their stories to make them more interesting than reality? 3. What expectations do these authors have about their readers, and what are the ethical implications for researchers like us who analyze their posts? To answer these questions, PhD Student Christopher Wienberg contacted many of these bloggers directly and set up face-to-face interviews at their homes. Accompanied by a documentary film crew, Christopher traveled to locations around California, in both urban and rural settings, to better understand the people whose contributions on the web serve as data in social media research.","PeriodicalId":93136,"journal":{"name":"Proceedings of the ...

Despite its success, little has been studied on the human behavior and interaction on this platform. This is important as it sheds light on the driving force behind Tumblr's growth. In this work, we present a quantitative study of Tumblr based on the complete data coverage for four consecutive months consisting of 23.2 million users and 10.2 billion posts. We first explore various attributes of users, posts, and tags in detail and extract behavioral patterns based on the user generated content. We then construct a massive reblog network based on the primary user interactions on Tumblr and present findings on analyzing its topological structure and properties. Finally, we show substantial results on providing location-specific usage patterns from Tumblr, despite no built-in support for geo-tagging or user location functionality. Essentially this is done by conducting a large-scale user alignment with a different social media platform (e.g., Twitter) and subsequently propagating geo-information across platforms. To the best of our knowledge, this work is the first attempt to carry out large-scale measurement-driven analysis on Tumblr.","PeriodicalId":93136,"journal":{"name":"Proceedings of the ...

Influence between people represented as nodes of a social graph is best characterized in terms of the direction, the volume and the delay associated with the information flow. In this work we investigate the relatively new information-theoretic measure called transfer entropy as a measure of directed causal influence in online social interactions. The classical definition of transfer entropy is extended to a form applicable to activity on social graphs characterized by causal influence through delayed responses. For fixed but arbitrary interaction delays, we show that the swept delayed transfer entropy (DTE) profile peaks at the true delay. By extending the results to discrete and continuous distributions of interaction delays, the efficacy of DTE in recovering the interaction delay distributions between two causally related signals is demonstrated. An information theoretic annotation of social graphs that captures the volume and velocity of information transfer is presented based on the swept DTE.","PeriodicalId":93136,"journal":{"name":"Proceedings of the ...

The general goal is to make inferences from observations collected from the numerous posts publicly available in blogs, microblogs, and other social forums. A traditional approach for collecting observations is by querying a random (or convenience) sample of individuals with surveys. A wide variety of well respected survey instruments have been developed over many decades especially in social sciences.The question addressed here is: how does one `translate' a survey of interest into surveillance strategies on social media? Specifically, how does one find the posts that could be interpreted as valid responses to the survey? Developing a general methodology for translating a survey into social medial surveillance might further the inclusion of social media research into traditional social science research. We propose a translation methodology using a well-reputed survey (the Satisfaction with Life Scale) as an example. A second methodological contribution that goes beyond the survey translation focus is a crowdsourcing approach, which we claim with reasonable confidence, finds close to ul{all} the relevant items in a dataset. This is different from the standard approach of asking workers to annotate all items in a small dataset. Our method supports more accurate evaluations (i.e., more precise recall calculations) as well as the development of larger training datasets. Finally the resulting surveillance method derived from the life satisfaction survey achieves recall, precision and F scores between 0.59 and 0.65. This is considerably better than standard methods using lexicons (precision around 0.16) or classifiers (precision, recall and F scores between 0.32 and 0.38).","PeriodicalId":93136,"journal":{"name":"Proceedings of the ...
