Beginners and Basics
Beginners & Basics S O C I A L M E D I A 1 0 1 Beginners W E L C O M E T O & Basics T W I T T E R 1 0 1 What is Twitter? Twitter is technically a “micro-blogging service,” allowing users to post and share comments, photos, videos and more. So what does that actually mean? Because it has a 240 character limit (recently bumped up from 140), it’s a place to share brief posts — not paragraphs. Twitter has some unique terminology when referring to specific features. It may be confusing to newbies, so we broke down the basics for you: Twitter Lingo Who Uses It? Tweet: to post With over 330 million monthly active users Retweet: to repost another user’s and 145 million daily active users, Twitter post has a huge influence. Many users are Reply: using the @ to respond to younger, but Twitter’s reach is not just someone’s post millennials and Gen-Z. Direct Message: private chat Hashtag: a symbol (the # sign) that 63% of Twitter users are between the ages categorizes tweets of 35 and 65. While other social media platforms like Snapchat and TikTok are Brands that are killing the Twitter game famous for catering to younger generations, it’s clear that Twitter appeals to a more mature audience as well. 17.7M 13.2M 11.2M 12M Why is it helpful? With such an impressive number of active users, Twitter is one of the best digital marketing tools for businesses. Twitter allows for brands and businesses to engage personally with their consumers. -
Effectiveness of Dismantling Strategies on Moderated Vs. Unmoderated
www.nature.com/scientificreports OPEN Efectiveness of dismantling strategies on moderated vs. unmoderated online social platforms Oriol Artime1*, Valeria d’Andrea1, Riccardo Gallotti1, Pier Luigi Sacco2,3,4 & Manlio De Domenico 1 Online social networks are the perfect test bed to better understand large-scale human behavior in interacting contexts. Although they are broadly used and studied, little is known about how their terms of service and posting rules afect the way users interact and information spreads. Acknowledging the relation between network connectivity and functionality, we compare the robustness of two diferent online social platforms, Twitter and Gab, with respect to banning, or dismantling, strategies based on the recursive censor of users characterized by social prominence (degree) or intensity of infammatory content (sentiment). We fnd that the moderated (Twitter) vs. unmoderated (Gab) character of the network is not a discriminating factor for intervention efectiveness. We fnd, however, that more complex strategies based upon the combination of topological and content features may be efective for network dismantling. Our results provide useful indications to design better strategies for countervailing the production and dissemination of anti- social content in online social platforms. Online social networks provide a rich laboratory for the analysis of large-scale social interaction and of their social efects1–4. Tey facilitate the inclusive engagement of new actors by removing most barriers to participate in content-sharing platforms characteristic of the pre-digital era5. For this reason, they can be regarded as a social arena for public debate and opinion formation, with potentially positive efects on individual and collective empowerment6. -

Opportunities and Challenges for Standardization in Mobile Social Networks
Opportunities and Challenges for Standardization in Mobile Social Networks Laurent-Walter Goix, Telecom Italia [email protected] Bryan Sullivan, AT&T [email protected] Abstract This paper describes the opportunities and challenges related to the standardization of interoperable “Mobile Social Networks”. Challenges addressed include the effect of social networks on resource usage, the need for social network federation, and the needs for a standards context. The concept of Mobile Federated Social Networks as defined in the OMA SNEW specification is introduced as an approach to some of these challenges. Further specific needs and opportunities in standards and developer support for mobile social apps are described, including potentially further work in support of regulatory requirements. Finally, we conclude that a common standard is needed for making mobile social networks interoperable, while addressing privacy concerns from users & institutions as well as the differentiations of service providers. 1 INTRODUCTION Online Social Networks (OSN) are dominated by Walled Gardens that have attracted users by offering new paradigms of communication / content exchange that better fit their modern lifestyle. Issues are emerging related to data ownership, privacy and identity management and some institutions such as the European Commission have started to provide measures for controlling this. The impressive access to OSN from ever smarter mobile devices, as well as the growth of mobile- specific SN services (e.g. WhatsApp) have further stimulated the mobile industry that is already starving for new attractive services (RCS 1). In this context OMA 2 as mobile industry forum has recently promoted the SNEW specifications that can leverage network services such as user identity and native interoperability of mobile networks (the approach promoted by “federated social networks”). -

Counterpart International would like to acknowledge and thank all who were involved in the creation of Social Networking: A Guide to Strengthening Civil Society through Social Media. This guide is a result of collaboration and input from a great team and group of advisors. Our deepest appreciation to Tina Yesayan, primary author of the guide; and Kulsoom Rizvi, who created a dynamic visual layout. Alex Sardar and Ray Short provided guidance and sound technical expertise, for which we’re grateful. The Civil Society and Media Team at the U.S. Agency for International Development (USAID) was the ideal partner in the process of co-creating this guide, which benefited immensely from that team’s insights and thoughtful contributions. The case studies in the annexes of this guide speak to the capacity and vision of the featured civil society organizations and their leaders, whose work and commitment is inspiring. This guide was produced with funding under the Global Civil Society Leader with Associates Award, a Cooperative Agreement funded by USAID for the implementation of civil society, media development and program design and learning activities around the world. Counterpart International’s mission is to partner with local organizations - formal and informal - to build inclusive, sustainable communities in which their people thrive. We hope this manual will be an essential tool for civil society organizations to more effectively and purposefully pursue their missions in service of their communities. -

Georg Groh Habilitationsschrift Mitglieder des Habilitationskomittees: Prof. Dr. Johann Schlichter Prof. Dr. Bettina Berendt Prof. Dr. Helmut Seidl Kurz-Zusammenfassung Der zentrale Gegenstand der vorliegenden Arbeit ist die vielschichtige Frage, wie Kontexte detektiert und abgeleitet werden k¨onnen,die dazu dienen k¨onnen,neuar- tige kontextbewusste Social Networking Dienste zu schaffen und bestehende Di- enste in ihrem Nutzwert zu verbessern. Die (noch nicht abgeschlossene) erfolgre- iche Umsetzung dieses Programmes f¨uhrtauf ein Konzept, das man als Contextual Social Networking bezeichnen kann. In einem grundlegenden ersten Teil werden die eng zusammenh¨angendenGebiete Contextual Social Networking, Mobile Social Networking und Decentralized Social Networking mit verschiedenen Methoden und unter Fokussierung auf verschiedene Detail-Aspekte n¨aherbeleuchtet und in Zusam- menhang gesetzt. Ein zweiter Teil behandelt die Frage, wie soziale Kurzzeit- und Langzeit-Kontexte als f¨urdas Social Networking besonders interessante Formen von Kontext gemessen und abgeleitet werden k¨onnen. Ein Fokus liegt hierbei auf NLP Methoden zur Charakterisierung sozialer Beziehungen als einer typischen Form von sozialem Langzeit-Kontext. Ein weiterer Schwerpunkt liegt auf Methoden aus dem Mobile Social Signal Processing zur Ableitung sinnvoller sozialer Kurzzeit-Kontexte auf der Basis von Interaktionsgeometrien und Audio-Daten. Es wird ferner unter- sucht, wie pers¨onliche soziale Agenten Kontext-Elemente verschiedener Abstraktion- sgrade miteinander kombinieren k¨onnen.Der dritte Teil behandelt neuartige und verbesserte Konzepte f¨urkontextbewusste Social Networking Dienste. Es werden spezielle Formen von Awareness Diensten, neue Formen von sozialem Information Retrieval, Konzepte f¨urkontextbewusstes Privacy Management und Dienste und Plattformen zur Unterst¨utzungvon Open Innovation und Kreativit¨atuntersucht und vorgestellt.
