Rethinking summarization and storytelling for modern social multimedia
Traditional summarization initiatives have been focused on specific types of documents such as articles, reviews, videos, image feeds, or tweets, a practice which may result in pigeonholing the summarization task in the context of modern, content-rich multimedia collections. Consequently, much of the research to date has revolved around mostly toy problems in narrow domains and working on single-source media types. We argue that summarization and story generation systems need to re-focus the problem space in order to meet the information needs in the age of user-generated content in different formats and languages. Here we create a framework for flexible multimedia storytelling. Narratives, stories, and summaries carry a set of challenges in big data and dynamic multi-source media that give rise to new research in spatial-temporal representation, viewpoint generation, and explanatio

entrench

Drawing
on

the

proposes
that
AUGC
can
potentially
disrupt
some
of

in
the

up

How content contributors assess and establish credibility on the web
The proliferation of user‐generated content (UGC) is one of the distinguishing characteristics of Web 2.0. Internet users contribute content online through platforms such as blogs, wikis, video sharing sites, and sites that allow user feedback. Yet little is known of the credibility practices of these content contributors. Through phone interviews conducted with 29 online content contributors, this study investigates how content contributors assess credibility when gathering information for their online content creation and mediation activities, as well as the strategies they use to establish the credibility of the content they create. These contributors reported that they engaged in content creation activities such as posting or commenting on blogs or online forums, rating or voting on online content, and uploading photos, music, or video. We found that credibility judgments made when gathering information for online content creation and mediation activities could be grouped into three levels: intuitive, heuristic, and strategy‐based. We identified three distinctive ways of establishing credibility that are applied during different phases of content contribution: ensuring credibility during the content creation phase; signaling credibility during the content presentation phase; and reinforcing credibility during the post‐production phase. We also discovered that content contributors tend to carry over the strategies they used for assessing credibility during information gathering to their strategies for establishing the credibility of their own content. Theoretical implications for credibility research and practical implications for developing information literacy programs are discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/90253/1/14504801163_ftp.pd
An analysis of purple truths: an alternative history of the school of journalism and media studies at Rhodes University. Exploring the possibilities of digital media for telling history through multiple voices
In theory, notions of public history and participatory journalism signal the ability of users to become active collaborators in the journalistic process with a degree of agency and authority over media content. Similarities in public history and participatory journalism are manifested in audience participation where the traditional and hegemonic boundaries between readers and journalists/historians are challenged. In this thesis, I present Purple Truths, a digital public history website about the School of Journalism and Media Studies at Rhodes University, that highlights multivocality and plurality. It allowed for democratisation of the historical narrative by inviting audience participation to historical inquiry on a digital platform. It was constructed as a case study for the thesis to investigate participatory processes. Using a five-dimensional model developed by Netzer et al. (2014) for the construction of participation on news websites, I identified five major participation features that revealed how and where participation was happening on the website. The features were mapped and tabulated according to Carpentier’s (2011) maximalist/minimalist dimensions of participation (access, interaction and ‘real’) to determine the degrees of participation in this study towards the aim of using the Purple Truths website to democratise the historical narrative. My findings suggest that despite a diversity of strategies, the study did have to rely on existing norms and practices of editorial decision-making, even in the context of digital media, and significant stages of the news-production process (selection/filtering) remained in the hands of researcher/editor. Maximalist participation, demonstrated as equalised power relations in decision-making, has a utopian dimension and is difficult to translate into practice. However, participation research requires further investigation in the digital humanities in South Africa to explore notions of democratisation of the narrative in academic and social praxis as sites of interdisciplinary democratic renewa
