Choudhury, Munmun De, Diakopoulos, Nicholas and Naaman, Mor (2012): Unfolding the event landscape on twitter: classification and exploration of user categories. In: Proceedings of ACM CSCW12 Conference on Computer-Supported Cooperative Work 2012. pp. 241-244.

Social media platforms such as Twitter garner significant attention from very large audiences in response to real-world events. Automatically establishing who is participating in information production or conversation around events can improve event content consumption, help expose the stakeholders in the event and their varied interests, and even help steer subsequent coverage of an event by journalists. In this paper, we take initial steps towards building an automatic classifier for user types on Twitter, focusing on three core user categories that are reflective of the information production and consumption processes around events: organizations, journalists/media bloggers, and ordinary individuals. Exploration of the user categories on a range of events shows distinctive characteristics in terms of the proportion of each user type, as well as differences in the nature of content each shared around the events.

Kivran-Swaine, Funda, Brody, Sam, Diakopoulos, Nicholas and Naaman, Mor (2012): Of joy and gender: emotional expression in online social networks. In: Companion Proceedings of ACM CSCW12 Conference on Computer-Supported Cooperative Work 2012. pp. 139-142.

In this study, we analyzed the language use on Twitter personal exchanges as well as properties of the users' networks, to study the influence of gender composition on expressions of positive emotions while controlling for the strength of connection between the conversing users. Our findings show that compared to men, women express positive emotions more, especially when interacting with other women. Our findings help the understanding of gender-driven communication patterns in social media, and offer insights for the study of emotion and language.

Diakopoulos, Nicholas and Naaman, Mor (2011): Towards quality discourse in online news comments. In: Proceedings of ACM CSCW11 Conference on Computer-Supported Cooperative Work 2011. pp. 133-142.

With the growth in sociality and interaction around online news media, news sites are increasingly becoming places for communities to discuss and address common issues spurred by news articles. The quality of online news comments is of importance to news organizations that want to provide a valuable exchange of community ideas and maintain credibility within the community. In this work we examine the complex interplay between the needs and desires of news commenters with the functioning of different journalistic approaches toward managing comment quality. Drawing primarily on newsroom interviews and reader surveys, we characterize the comment discourse of SacBee.com, discuss the relationship of comment quality to both the consumption and production of news information, and provide a description of both readers' and writers' motivations for usage of news comments. We also examine newsroom strategies for dealing with comment quality as well as explore tensions and opportunities for value-sensitive innovation within such online communities.

Diakopoulos, Nicholas, Kivran-Swaine, Funda and Naaman, Mor (2011): Playable data: characterizing the design space of game-y infographics. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 1717-1726.

This work explores the intersection between infographics and games by examining how to embed meaningful visual analytic interactions into game mechanics that in turn impact user behavior around a data-driven graphic. In contrast to other methods of narrative visualization, games provide an alternate method for structuring a story, not bound by a linear arrangement but still providing structure via rules, goals, and mechanics of play. We designed two different versions of a game-y infographic, Salubrious Nation, and compared them to a non-game-y version in an online experiment. We assessed the relative merits of the game-y approach of presentation in terms of exploration of the visualization, insights and learning, and enjoyment of the experience. Based on our results, we discuss some of the benefits and drawbacks of our designs. More generally, we identify challenges and opportunities for further exploration of this new design space.

Diakopoulos, Nicholas and Naaman, Mor (2011): Topicality, time, and sentiment in online news comments. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 1405-1410.

In this paper we examine the relationships between news comment topicality, temporality, sentiment, and quality in a dataset of 54,540 news comments. Initial observations indicate that comment sentiments, both positive and negative, can be useful indicators of discourse quality, and that aggregate temporal patterns in positive sentiment exist on comment threads.

Luther, Kurt, Diakopoulos, Nicholas and Bruckman, Amy (2010): Edits & credits: exploring integration and attribution in online creative collaboration. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 2823-2832.

Attribution allows online reputations to be formed and motivates many contributions to online creative collaboration. Yet, we know little about attribution practices in online creative collaboration and the technologies that shape them. This paper describes a study of online collaborative animation projects, focused on the practices surrounding integration and attribution. We found that both tasks are closely related and often completed by a single person, a process we call "cr-editing." We also identify frustrations with existing practices and systems and propose design considerations for alleviating them. Our findings offer insights into the growing space of online remixing, mashups, and creativity.

Diakopoulos, Nicholas (2010): Game-y information graphics. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 3595-3600.

In this paper we explore the application of formal elements of games such as goals and scores to information graphics?so called "game-y" information graphics. In order to study how game-y aspects could engender exploration of a dataset, we built two versions of an information graphic, one without game elements and the other incorporating aspects of trivia games. Preliminary results based on a real world deployment of the graphics on a newspaper website suggest that the trivia game information graphic engendered increased exploration of the data space by users as compared to the regular version of the graphic.

Yu, Zihao, Diakopoulos, Nicholas and Naaman, Mor (2010): The multiplayer: multi-perspective social video navigation. In: Proceedings of the 2010 ACM Symposium on User Interface Software and Technology 2010. pp. 413-414.

We present a multi-perspective video "multiplayer" designed to organize social video aggregated from online sites like YouTube. Our system automatically time-aligns videos using audio fingerprinting, thus bringing them into a unified temporal frame. The interface utilizes social metadata to visually aid navigation and cue users to more interesting portions of an event. We provide details about the visual and interaction design rationale of the multiplayer.

Diakopoulos, Nicholas, Goldenberg, Sergio and Essa, Irfan (2009): Videolyzer: quality analysis of online informational video for bloggers and journalists. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 799-808.

Tools to aid people in making sense of the information quality of online informational video are essential for media consumers seeking to be well informed. Our application, Videolyzer, addresses the information quality problem in video by allowing politically motivated bloggers or journalists to analyze, collect, and share criticisms of the information quality of online political videos. Our interface innovates by providing a fine-grained and tightly coupled interaction paradigm between the timeline, the time-synced transcript, and annotations. We also incorporate automatic textual and video content analysis to suggest areas of interest for further assessment by a person. We present an evaluation of Videolyzer looking at the user experience, usefulness, and behavior around the novel features of the UI as well as report on the collaborative dynamic of the discourse generated with the tool.

Diakopoulos, Nicholas, Luther, Kurt, Medynskiy, Yevgeniy and Essa, Irfan (2007): The evolution of authorship in a remix society. In: Proceedings of the Eighteenth ACM Conference on Hypertext and Hypermedia 2007. pp. 133-136.

Authorship entails the constrained selection or generation of media and the organization and layout of that media in a larger structure. But authorship is more than just selection and organization; it is a complex construct incorporating concepts of originality, authority, intertextuality, and attribution. In this paper we explore these concepts and ask how they are changing in light of modes of collaborative authorship in remix culture. We present a qualitative case study of an online video remixing site, illustrating how the constraints of that environment are impacting authorial constructs. We discuss users' self-conceptions as authors, and how values related to authorship are reflected to users through the interface and design of the site's tools. We also present some implications for the design of online communities for collaborative media creation and remixing.

Diakopoulos, Nicholas and Essa, Irfan (2006): Videotater: an approach for pen-based digital video segmentation and tagging. In: Proceedings of the ACM Symposium on User Interface Software and Technology 2006. pp. 221-224.

The continuous growth of media databases necessitates development of novel visualization and interaction techniques to support management of these collections. We present Videotater, an experimental tool for a Tablet PC that supports the efficient and intuitive navigation, selection, segmentation, and tagging of video. Our veridical representation immediately signals to the user where appropriate segment boundaries should be placed and allows for rapid review and refinement of manually or automatically generated segments. Finally, we explore a distribution of modalities in the interface by using multiple timeline representations, pressure sensing, and a tag painting/erasing metaphor with the pen.

Diakopoulos, Nicholas and Essa, Irfan (2005): Mediating photo collage authoring. In: Proceedings of the 2005 ACM Symposium on User Interface Software and Technology 2005. pp. 183-186.

The medium of collage supports the visualization of meaningful event summaries using photographs. It can however be rather tedious to author a collage from a large collection of photographs. In this work we present an approach that supports efficient construction of a collage by assisting the user with an automatic layout procedure that can be controlled at a high level. Our layout method utilizes a pre-designed template which consists of cells for photos and annotations applied to these cells. The layout is then filled by matching the metadata of photos to the annotations in the cells using an optimization algorithm. The user exercises flexibility in the authoring process by (a) maintaining high-level control through the types of constraints applied and (b) leveraging visual emphases supported by the layout algorithm. The user can of course provide fine-grained control of the final collage through direct manipulation. Off-loading the tedium of collage construction to a user controlled yet automated process clears the way for rapidly generating different views of the same album and could also support the increased sharing of digital photos in the form of compact collages.
