ABSTRACT
In this chapter, many of the fundamental network relationships and structures are presented in the context of information spread through social media linked individuals and groups. Core social networks relationship terminology, such as symmetry, directionality, intermediary relationships, and network complexity are addressed. Relationship structures, such as dyadic, triadic, and balanced relationships are also summarized in simple terms. The concept of homophily and filter bubbles as communication echo chambers are described using a modern example: the dwindling trust in mass media. The chapter concludes with an overview of several popular social network visualization and analysis software tools. Social networks are analyzed at varying scales, but the primary purpose of social network analysis is to ultimately utilize mathematical models to study the structure, development, and evolution of the social network. In the realm of sociology, the most straightforward grouping consists of two individuals, also known as a dyad.
