104. Accountability in Algorithmic Decision Making.

Author

DIAKOPOULOS, NICHOLAS

Subjects
*DECISION making, *ALGORITHMS, *AUTOMATION, *RESPONSIBILITY, *DISCLOSURE
Abstract

The article discusses the role of accountability in algorithmic or automated decision making. Details on various types of algorithmic decision making, such as prioritization, classification, association, and filtering are presented. The author examines accountability in both the private and public sectors and suggests that an algorithmic transparency standard should be created which includes disclosure of information surrounding human involvement, data, modeling, and inferences, and algorithmic presence. User experience is also discussed.

Abstract

International audience; This report documents the program and the outcomes of Dagstuhl Seminar 16061 “Data-Driven Storytelling”. Close to forty researchers and practitioners descended on Schloss Dagstuhl to forge an interdisciplinary agenda on the topic of data-driven storytelling using visualization in early February, 2016. With burgeoning research interest in understanding what makes visualization effective for communication, and with practitioners pushing the envelope of the craft of visual communication, the meeting put different modes of thinking between computer science researchers and data visualization practitioners in close proximity for a week.

111. Algorithmic Accountability Reporting: On the Investigation of Black Boxes

Author

Diakopoulos, Nicholas

Subjects
Journalism, Journalism--Methodology, Journalism--Data processing
Abstract

How can we characterize the power that various algorithms may exert on us? And how can we better understand when algorithms might be wronging us? What should be the role of journalists in holding that power to account? In this report I discuss what algorithms are and how they encode power. I then describe the idea of algorithmic accountability, first examining how algorithms problematize and sometimes stand in tension with transparency. Next, I describe how reverse engineering can provide an alternative way to characterize algorithmic power by delineating a conceptual model that captures different investigative scenarios based on reverse engineering algorithms’ input-output relationships. I then provide a number of illustrative cases and methodological details on how algorithmic accountability reporting might be realized in practice. I conclude with a discussion about broader issues of human resources, legality, ethics, and transparency.

122. Negotiating Change: Audience Engagement Editors as Newsroom Intermediaries.

Author

Assmann, Karin and Diakopoulos, Nicholas

Subjects
AMERICAN journalism, TELEVISION editors, MASS media audiences
Abstract

In an effort to address their newly empowered and increasingly fragmented audiences, many newsrooms are hiring editors tasked with audience engagement. This paper investigates this new genre of news workers, the scope of their activity and their roles within news organizations. Interviews with 22 audience engagement editors working in 20 U.S. news organizations show how they conceptualize journalism, journalistic practices and standards, and how engagement strategies fulfill important institutional functions. Audience engagement editors serve as multi-tasking intermediaries between reporters, editors, advertisers, and their audiences. [ABSTRACT FROM AUTHOR]

128. A Survey on Assessment and Ranking Methodologies for User-Generated Content on the Web.

Abstract

User-generated content (UGC) on the Web, especially on social media platforms, facilitates the association of additional information with digital resources; thus, it can provide valuable supplementary content. However, UGC varies in quality and, consequently, raises the challenge of how to maximize its utility for a variety of end-users. This study aims to provide researchers and Web data curators with comprehensive answers to the following questions: What are the existing approaches and methods for assessing and ranking UGC? What features and metrics have been used successfully to assess and predict UGC value across a range of application domains? What methods can be effectively employed to maximize that value? This survey is composed of a systematic review of approaches for assessing and ranking UGC: results are obtained by identifying and comparing methodologies within the context of short text-based UGC on the Web. Existing assessment and ranking approaches adopt one of four framework types: the community-based framework takes into consideration the value assigned to content by a crowd of humans, the end-user–based framework adapts and personalizes the assessment and ranking process with respect to a single end-user, the designer-based framework encodes the software designer’s values in the assessment and ranking method, and the hybrid framework employs methods from more than one of these types. This survey suggests a need for further experimentation and encourages the development of new approaches for the assessment and ranking of UGC. [ABSTRACT FROM AUTHOR]

132. Algorithmic Transparency in the News Media

Author

Diakopoulos, Nicholas and Koliska, Michael

Abstract

The growing use of difficult-to-parse algorithmic systems in the production of news, from algorithmic curation to automated writing and news bots, problematizes the normative turn toward transparency as a key tenet of journalism ethics. Pragmatic guidelines that facilitate algorithmic transparency are needed. This research presents a focus group study that engaged 50 participants across the news media and academia to discuss case studies of algorithms in news production and elucidate factors that are amenable to disclosure. Results indicate numerous opportunities to disclose information about an algorithmic system across layers such as the data, model, inference, and interface. Findings underscore the deeply entwined roles of human actors in such systems as well as challenges to adoption of algorithmic transparency including the dearth of incentives for organizations and the concern for overwhelming end-users with a surfeit of transparency information.

147. Structure and Content of the Discourse on Climate Change in the Blogosphere: The Big Picture.

Author

Abstract

Based on the texts of 1.3 million blog posts and the structure of the links between the blogs in which these posts appeared, this study presents an analysis of the discourse on climate change in the English-language blogosphere. Our approach combines community detection with probabilistic topic modeling to show how topics related to climate change are discussed across various parts of the blogosphere. We find that there is one community of predominantly climate skeptical blogs but several accepter communities. The topic analysis reveals a series of issues that are characteristic of the climate change discourse in the blogosphere. Two topics, one related to climate change science and one related to climate change politics, are particularly important for characterizing the discourse. We also find that the distribution of topics over the communities cuts across the divide between skeptics and non-skeptics (accepters) and that there are differences in the patterns of interactions between the skeptics and different groups of accepters.
