CIMTDetect: A Community Infused Matrix-Tensor Coupled Factorization Based Method for Fake News Detection

Detecting whether a news article is fake or genuine is a crucial task in today's digital world where it's easy to create and spread a misleading news article. This is especially true of news stories shared on social media since they don't undergo any stringent journalistic checking associated with main stream media. Given the inherent human tendency to share information with their social connections at a mouse-click, fake news articles masquerading as real ones, tend to spread widely and virally. The presence of echo chambers (people sharing same beliefs) in social networks, only adds to this problem of wide-spread existence of fake news on social media. In this paper, we tackle the problem of fake news detection from social media by exploiting the very presence of echo chambers that exist within the social network of users to obtain an efficient and informative latent representation of the news article. By modeling the echo-chambers as closely-connected communities within the social network, we represent a news article as a 3-mode tensor of the structure - and propose a tensor factorization based method to encode the news article in a latent embedding space preserving the community structure. We also propose an extension of the above method, which jointly models the community and content information of the news article through a coupled matrix-tensor factorization framework. We empirically demonstrate the efficacy of our method for the task of Fake News Detection over two real-world datasets. Further, we validate the generalization of the resulting embeddings over two other auxiliary tasks, namely: \textbf{1)} News Cohort Analysis and \textbf{2)} Collaborative News Recommendation. Our proposed method outperforms appropriate baselines for both the tasks, establishing its generalization.Comment: Presented at ASONAM'1

A framework for interrogating social media images to reveal an emergent archive of war

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

Unconventional TV Detection using Mobile Devices

Recent studies show that the TV viewing experience is changing giving the rise of trends like "multi-screen viewing" and "connected viewers". These trends describe TV viewers that use mobile devices (e.g. tablets and smart phones) while watching TV. In this paper, we exploit the context information available from the ubiquitous mobile devices to detect the presence of TVs and track the media being viewed. Our approach leverages the array of sensors available in modern mobile devices, e.g. cameras and microphones, to detect the location of TV sets, their state (ON or OFF), and the channels they are currently tuned to. We present the feasibility of the proposed sensing technique using our implementation on Android phones with different realistic scenarios. Our results show that in a controlled environment a detection accuracy of 0.978 F-measure could be achieved.Comment: 4 pages, 14 figure

Paradox of Social Presence in Online Learning in the Age of Social media

How often do you think of social presence (a feeling of being there and connected with others in a computer mediated communication) when designing and/or delivering your online course(s) or instruction? Does it even make sense to worry about it in the age of social media

From 328,513 Likes to 1 Million Protestors: How Social Media Amplified Collective Action During the Egyptian Revolution Through Increased Communication and Identity Formation

Our world is increasingly becoming connected through the use of technology, the Internet, and social media networks. Through social media we are able to stay connected in real time, becoming witnesses to each other\u27s lives. This thesis explores how social media amplifies the way we communicate and form identities with one another. Specifically this thesis examines how activists used social media to communicate, mobilize, and form a sense of Egyptian pride throughout the Egyptian Revolution. Throughout the revolution, social media impacted how activists were networking with one another enabling for the demands of the people to be heard- ultimately for the resignation of Egyptian President Mubarak. Eighteen days after the revolution started on January 25,2011 , Mubarak resigned as social media networks contributed to the communication and virtual responses of over three thousand likes on the Facebook page We are all Khaled Saieed. Yet, more importantly it was the physical presence of over one million people acting collectively to end their oppression under Mubarak\u27s regime on February 11, 2011. So in a time of rising technology, I ask if social media was the essential component for social movements or if the empowering component lies within our physical interactions

YOUTUBE AS A DA'WAH MEDIA

The development of technology is currently experiencing rapid progress, a variety of media provide information without limit and time. Progress from various media in the information age has experienced significant changes in terms of actors, methods and effects. The presence of the internet and information products has succeeded in breaking through geographical barriers, national, racial, cultural and cultural boundaries. Citizens' activities are now increasingly important, considering that everyone can be directly connected through a global information network. The development in technology has a big influence on social life, especially in Indonesia, which easily access information offered by social media. The positive side of the presence of technology is that we can get various information about developments in various sectors both religion, education, economy, social culture and politics. While the negative elements are impressions that are not educational, full of violence and irrational. In various popular media, the presence of YouTube has become one of the easy tools in spreading da'wah, where people no longer have difficulty watching and listening to religious studies that are not always shown on the media such as on television. Da'wah through YouTube media has included various groups of people both parents, teenagers and children, in addition to making it easy for the preachers (preachers) to spread the teachings of Islam through YouTube also makes it easy for the public to access various lectures that he wants to listen to a variety of different topics and speakers.Keywords: youtube, media, dakwa

"Replacing Teachers? Doubt it." : Practitioners' Views on Adaptive Learning Technologies' Impact on the Teaching Profession

Novel learning technologies have potential in reshaping the teaching profession by automating some parts of the work. However, teachers' perspectives towards automation have generally been critical. In the present study, we examine Finnish education practitioners’ thoughts on adaptive learning technologies and their impact on the teaching profession. Using thematic and epistemic network analysis (ENA), we analyzed 114 social media posts. Supportive posts connected technological capabilities and self-directed or self-regulated learning, emphasizing that technology can also guide and support students. Critical posts connected human presence, educational arrangements, and pupil diversity and equality, emphasizing the importance of teachers’ presence in addressing pupils’ varying needs. Overall, the role of a human teacher was seen as necessary even with adaptive learning technologies available. Our findings reveal themes relevant when discussing the development of adaptive learning technologies and their potential impact on the teaching profession. Moreover, our findings increase the understanding of how supportive and critical argumentation on technology differ.Peer reviewe
