The issue of privacy in social networks is a hot topic today, because of the growing amount of information shared among users, who are connected to social media every moment and by different devices and displays. This chapter presents a usability evaluation of the privacy features of Facebook's social network. The authors carry out an evaluation composed by three approaches, executed in three stages: first by the analysis and inspection of system's features related to privacy, available for both systems (Web-based systems and mobile-based systems, e.g. app). The second step is a heuristic evaluation led by three experts, and finally, the third step is a questionnaire with 605 users to compare the results between specialists and real users. This chapter aims to present the problems associated with these privacy settings, and it also wants to contribute for improving the user interaction with this social network.

Media Mining

The emergence of Web-based communities and social networking sites has led to a vast volume of social media data, embedded in which are rich sets of meaningful knowledge about the social networks. Social media mining and social network analysis help to find a systematic method or process for examining social networks and for identifying, extracting, representing, and exploiting meaningful knowledge—such as interdependency relationships among social entities in the networks—from the social media. This chapter presents a system for analyzing the social networks to mine important groups of friends in the networks. Such a system uses a tree-based mining approach to discover important friend groups of each social entity and to discover friend groups that are important to social entities in the entire social network.

During the fast growth of social media, the ways companies usually use in their marketing are changed; social networks became a great approach for companies to improve their communication with customers. The wide usage of social networking sites and tools by individuals makes companies want to think carefully on how they can benefit from such usage in rebuilding their relationship with customers and increasing their engagement level. Such companies found that social media marketing is the solution through which companies and their customers will become much closer. This chapter covers three main sections where traditional marketing and electronic marketing concepts are reviewed in the first section. Then a detailed exploration of social networks and their distinct features is presented in the second section.

Bounded System

Social networking is a Web-based service that allows individuals to construct a public or semi-public profile within a bounded system, articulate a list of other users with whom they share a connection, and view and navigate their list of connections and those made by others within the system. No doubt, social media has great potential in taking library operations to the next level. It is in the light of this that this chapter examines the role of social media and social networking in information service provision in libraries. To achieve this objective, the chapter looks at social media as a tool in libraries, advantages of social media in libraries, social media and social networks, and practical examples on the use of social media and social network tools together with how libraries can forge ahead due to the use and application of social media and social networks to their daily operations. Conclusion and recommendations based on these highlights are provided.

Abstract. Science needs everyone and everything; therefore, art must be used for its understanding. As the popularity of social media grows, absurd theories have been gaining consensus and, even worse, becoming factual truths without any criticism for many. Thus, aiming to find solutions for a better understanding of our scientific theories, the project “The earth is flat! And, now what?” was created. This project uses performing art as the main communicator to spread science. The first step consisted of calling a meeting to promote integration among the project participants and professionals from different areas of expertise such as geophysicists, art educators, artists, astronomers, and clowns. The meeting was also an occasion for planning the show. The second step consisted of developing the dramaturgy along with the creative process, which involved discussions on scenes and lessons about the theme to be presented, and the third step was the performance. The bibliographical review, the equivalent of the “table's work” for artists, was not based on indexed journals, but rather on social networks and classes for understanding the shape of the Earth. The show impacts the audience in a fun way, offering the opportunity for the general population to experience science in a new way.

Abstract. Science needs everything, and art must feed on it for its actions. With the growing popularity of social media, absurd theories have been gaining consensus without any criticism, and, even worse, they have consolidated. Thus, in order to find solutions for a better understanding of our theories, it was created the project "The Earth is Flat! Now What?", that uses performing art as the main communicator to spread science. The first step was a meeting for promoting integration among Geophysicists, Art-educators, Artists, Astronomers, clowns and all the different expertise participating in the project. The meeting was also the occasion for planning the show. The second step was the dramaturgy along with the creative process, which involved discussions of the scenes and lessons about the theme to be presented. And the third step was the performance. The bibliographical review, which is the same method named the “table's work” for artists, was not based on indexed journals, but rather on social networks and classes for understanding the shape of the Earth. The show impacts the community in a fun way offering the opportunity of a new experience to the population.

Complex Events

Popularity of the social media and the amount of importance given by an individual to social media has significantly increased in last few years. As more and more people become part of the social networks like Twitter, Facebook, information which flows through the social network, can potentially give us good understanding about what is happening around in our locality, state, nation or even in the world. The conceptual motive behind the project is to develop a system which analyses about a topic searched on Twitter. It is designed to assist Information Analysts in understanding and exploring complex events as they unfold in the world. The system tracks changes in emotions over events, signalling possible flashpoints or abatement. For each trending topic, the system also shows a sentiment graph showing how positive and negative sentiments are trending as the topic is getting trended.

The Individual

Social networking users are presented with a plethora of profile and privacy settings; most of which are left defaulted. As a result, there is little understanding of the fields that make up the user profile, the privacy settings available to safeguard the user, and the ramifications of not changing the same. Concerns relating to the unprecedented quantities of Personally Identifiable Information being stored need to be addressed. By employing a risk matrix to a social media profile, a user could be alerted to the potential dangers of the information being contained within the profile. By adapting this tool, the risks to the individual user of a social media profile will be minimised.

The Impact

Nowadays, social networks play a crucial role in human everyday life and no longer purely associated with spare time spending. In fact, instant communication with friends and colleagues has become an essential component of our daily interaction giving a raise of multiple new social network types emergence. By participating in such networks, individuals generate a multitude of data points that describe their activities from different perspectives and, for example, can be further used for applications such as personalized recommendation or user profiling. However, the impact of the different social media networks on machine learning model performance has not been studied comprehensively yet. Particularly, the literature on modeling multi-modal data from multiple social networks is relatively sparse, which had inspired us to take a deeper dive into the topic in this preliminary study. Specifically, in this work, we will study the performance of different machine learning models when being learned on multi-modal data from different social networks. Our initial experimental results reveal that social network choice impacts the performance and the proper selection of data source is crucial.
