AbstractThe dependability of visual information on the web and the authenticity of digital media appearing virally in social media platforms has been raising unprecedented concerns. As a result, in the last years the multimedia forensics research community pursued the ambition to scale the forensic analysis to real-world web-based open systems. This survey aims at describing the work done so far on the analysis of shared data, covering three main aspects: forensics techniques performing source identification and integrity verification on media uploaded on social networks, platform provenance analysis allowing to identify sharing platforms, and multimedia verification algorithms assessing the credibility of media objects in relation to its associated textual information. The achieved results are highlighted together with current open issues and research challenges to be addressed in order to advance the field in the next future.

AbstractThe practice of profile making has become ubiquitous in digital culture. Internet users are regularly invited, and usually required, to create a profile for a plethora of digital media, including mega social media platforms such as Facebook and Twitter. Understanding profiles as a set of identity performances, I argue that the platforms employ profiles to enable and incentivize particular ways and foreclose other ways of self-performance. Drawing on research into digital media and identities, combined with mediatization theories, I show how the platforms: (a) embrace datafication logic (gathering as much data as possible and pinpointing the data to a particular unit); (b) translate the logic into design and governance of profiles (update stream and profile core); and (c) coax—at times coerce—their users into making of abundant but anchored selves, that is, performing identities which are capacious, complex, and volatile but singular and coherent at the same time.

With the advent of popular social media platforms, news journalism has been forced to re-evaluate its relation to its audience. This applies also for public service media that increasingly have to prove its utility through audience ratings. This ethnographic study explores a particular project, the development of ‘concept bible’ for the Finnish Broadcasting Company YLE’s online news; it is an attempt to solve these challenges through new journalistic practices. The study introduces the concept of ‘nuanced universality’, which means that audience groups’ different kinds of needs are taken into account on news production in order to strengthen all people’s ability to be part of society. On a more general level, the article claims that despite its commercial origins, audience segmentation can be transformed into a method that helps revise public service media principles into practices suitable for the digital media environment.

Electoral Behaviour

The 2019 election witnessed a society that was consuming digital technology .For the first time in the history of India’s political platform the national elections were fought both on the streets and by using the smart phones and social media platforms using the digital technology .The digital media teams of the political parties in the 2019 elections played a very crucial role in trying to tip the scales in the favor of their party .The NaMo app had nearly 10 million downloads while the Shakti app of the Congress had around 70-80 lakh users. But the critics raised the question what if the party that mis-adopted the technology during 2019 is also the majority party in the house that would be responsible for designing the control mechanisms?

Four Levels

This article maps out how people in queer communities on Reddit navigate context collapse. Drawing upon data from interviews with queer Reddit users and insights from other studies of context collapse in digital media, we argue that context collapse also occurs in anonymity-based social media. The interviews reveal queer Reddit users’ practices of context differentiation, occurring at four levels: somatic, system, inter-platform and intra-platform. We use these levels to map out how lesbian, gay, bisexual, transgender and queer or questioning (LGBTQ) people express their identities and find community on Reddit while seeking to minimize the risks imposed by multiple impending context collapses. Because living an authentic queer life can make subjects vulnerable, we find that despite Reddit’s anonymity, sophisticated practices of context differentiation are developed and maintained. We argue that context collapse in an era of big data and social media platforms operates beyond the control of any one user, which causes problems, particularly for queer people.

PurposeThe current study seeks to present and examine the strategies, management and dissemination of information on social media platforms by Israeli government organizations and agencies.Design/methodology/approachThe article uses the “Case Study” approach, through semi-structured, in-depth interviews conducted with directors in charge of the use of social media in government departments.FindingsThe findings indicate that government agencies tend to favor Facebook over other social network platforms, in order to reach the widest possible audience. They do this by adhering to the platform's limitations, such as regularly using sponsored advertising to increase reach and visibility, and also by publishing visual content, such as videos and images, at the expense of text. In addition, the impact of respondents to adopt social media outweighs the use and importance awarded to traditional government websites. A clear preference is evident toward cultivating and strengthening existing information on social media at the expense of further developing official websites.Originality/valueFindings and conclusions from this type of research can help digital media directors and content editors in government agencies, to improve the quality of their content and improve the accessibility of the information they share online. In addition, the findings of the study strengthen the growing body of knowledge focused on the relationship between government ministries and social media.

Use Of Internet

<p>This is the first such study of the use of Internet by political parties in Indonesia. It also documents parties’ websites performance index and online popularity for campaigning in 2019. The purpose of this comparative study is to look at how the Internet was used by Indonesian political parties approaching the 2019 elections. Internet campaign consists of two parts: online presence through political party website, and political marketing through social media. Total of 16 parties participating the elections next year were examined for how they are utilizing official websites and social media platforms. We created an index based on list of website features (scoring system) and then classify it into 4 variables (information provision, mobilization, engagement, and technological sophistication) containing 43 features. We also visualise the descriptive statistical analysis on parties’ social media accounts using RStudio software. The study found that despite half of Indonesian national population is using the Internet, political parties were not yet achieving their maximum potential in using the digital media to disseminate political messages and propaganda. The quality of most of the websites have been subpar. In addition, the quality seems to have no relationship with the financial resources and the current parliamentary size of political parties. On average, official social media accounts run by parties has only been used in the last 3.25 years. Well-established older parties in Indonesia continue to engage with their constituents without heavily relying on social media. Yet, this situation is very likely to change in the future as parties’ elites are now beginning to look into this platform as they seek out to the millennials for electoral support.</p>

This research project is an interpretation of a societal phenomenon in terms of the culture of using digital application for leisure and entertainment especially regarding the human behaviour and its obsession of using these applications in the social media platforms. This idea was translated by using the idea of an installation of a fabricated sculpture. The idea of how the digital media plays a major role for leisure and its obsession was inspired by the artist Scott Snibbe. This reference includes on how netizens utilize and share their interests and interactions with these digital media, games and other kinds of digital media entertainments. The method used for this practical studio research are through self critical evaluation, studio experimentation and contextual reviews. This research project was intended to contribute to the field of fine arts in terms of collecting symbolic visual narratives and its issues of the collective culture in regarding of leisure and entertainment and its popularity as a life style today. With hope this research project will give a major impact in terms of understanding towards its trend and the digital entertainment itself. The variation, the ever changing content of its application has impacted the popular culture itself through its spirit and behaviour, the wants and needs projected by the new expression of consumerism.

The detection of manipulated videos represents a highly relevant problem in multimedia forensics, which has been widely investigated in the last years. However, a common trait of published studies is the fact that the forensic analysis is typically applied on data prior to their potential dissemination over the web. This work addresses the challenging scenario where manipulated videos are first shared through social media platforms and then are subject to the forensic analysis. In this context, a large scale performance evaluation has been carried out involving general purpose deep networks and state-of-the-art manipulated data, and studying different effects. Results confirm that a performance drop is observed in every case when unseen shared data are tested by networks trained on non-shared data; however, fine-tuning operations can mitigate this problem. Also, we show that the output of differently trained networks can carry useful forensic information for the identification of the specific technique used for visual manipulation, both for shared and non-shared data.

High Effort

There is a growing body of research on the interplay between increasingly digitally informed political campaigning and citizen engagement in the political sphere both on and offline. While much of the existing scholarship concerns how digital technology impacts engagement, participation and the spread of information, there is limited research into the ways in which specific digital content modes and social media platforms intersect in ways that can lead to increased involvement of individuals in high-effort political activities. This research paper focuses on the personal action framing of campaign videos created in support of the Labour Party’s general election campaign in 2017. Videos created by both the central campaign and the grassroots political organization Momentum were designed to be shared widely over social media platforms to achieve visibility over a broad network of supporters and undecided voters over the course of the campaign. By analyzing the content of these videos, I will show how specific instances of digital media, such as videos, can invite instances of high-effort political participation through personalized political action framing. Drawing on connective action theory, and in particular, the discussion of personalized politics (Bennett, 2012; Bennett & Segerberg, 2013), this research uses thematic content analysis to identify which high-effort political activities are alluded to most often in the video content. By comparing the videos produced by Labour with those of Momentum, this contribution addresses a gap in the existing literature as it relates to how campaigns can benefit from loosely connected ties to organizations that use digital media to expend their networks of influence to develop their strategic capacity. The methods explored in this research can inform future study on the use of campaign videos in political movement building and election campaigns.

Identification Techniques

The visual image has long been central to how war is seen, contested and legitimised, remembered and forgotten. Archives are pivotal to these ends as is their ownership and access, from state and other official repositories through to the countless photographs scattered and hidden from a collective understanding of what war looks like in individual collections and dusty attics. With the advent and rapid development of social media, however, the amateur and the professional, the illicit and the sanctioned, the personal and the official, and the past and the present, all seem to inhabit the same connected and chaotic space. However, to even begin to render intelligible the complexity, scale and volume of what war looks like in social media archives is a considerable task, given the limitations of any traditional human-based method of collection and analysis. We thus propose the production of a series of ‘snapshots’, using computer-aided extraction and identification techniques to try to offer an experimental way in to conceiving a new imaginary of war. We were particularly interested in testing to see if twentieth century wars, obviously initially captured via pre-digital means, had become more ‘settled’ over time in terms of their remediated presence today through their visual representations and connections on social media, compared with wars fought in digital media ecologies (i.e. those fought and initially represented amidst the volume and pervasiveness of social media images). To this end, we developed a framework for automatically extracting and analysing war images that appear in social media, using both the features of the images themselves, and the text and metadata associated with each image. The framework utilises a workflow comprising four core stages: (1) information retrieval, (2) data pre-processing, (3) feature extraction, and (4) machine learning. Our corpus was drawn from the social media platforms Facebook and Flickr.
