       Abstract

      Evaluating the public data from person-to-person communication destinations through the social network could create invigorating outcomes and bits of knowledge on the general assessment of practically any product, administration, or conduct. One of the best and precise public notion pointers is through information mining from social networks, as numerous clients seem to state their viewpoints on the social networks. The innovation in the Internet technologies figured out how to expand action in contributing to a blog, labeling, posting, and online informal communication. Therefore, individuals are beginning to develop keen on mining these immense information assets to evaluate the viewpoints. The Social Network Analysis (SNA) is the way toward researching social designs using graph hypothesis and networks. It integrates an assortment of procedures for analyzing the design of informal organizations, in addition with the hypotheses that target describing the hidden elements and the patterns in this framework. It is an intrinsically integrative field, which initially emerged from the sectors of graph hypothesis, statistics, and sociopsychology. This chapter will cover the hypothesis of SNA, with a short prologue to graph hypothesis and data spread. Then discuss the role of Python in SNA, followed up by building and suggesting informal communities from genuine Pandas and text-based data sets.

1.1 Introduction—Social Network Analysis

      A network of interactions, where the nodes comprise of number of people, and the edges comprise of interaction among the people are termed as social network [1]. The numbers of social networks and the strategies to analyze them are available since the past decades [2]. Statistics, graph theory, and sociology are the basics for the development of the area of social networks and are used in number of fields, such as business, economy, and information science [3, 4]. The analysis of a social network is analogous to the analysis of a graph because of the presence of graph, like topology of the social network. Graph analysis consists of a number of strategies but is not suitable to analyze the social networks [5–7] because of its complex characteristics. A very large-sized social network comprises of millions of edges and nodes, where the node generally possess number of attributes. The complex and large graph of social network cannot be managed using the old graph analysis strategies [8].

Email network, collaboration network, and telephone network are the various types of social networks. However, recent online social networks, like Twitter, Facebook, and LinkedIn, have gained increased popularity within a short period with a greater number of users. It was found with a survey that Facebook has crossed more than 500 million users in the year 2010 [8]. Social media acts as a highly recognized platform with rich source of data assisting well in the field of marketing of various brands, responding to changes in marketing, enhancing the brands through promotion, and eventually attaining a large number of customers [9–11]. In particular, the role of social network is very important in the area of healthcare applications. As such, the healthcare sector requires discovering new traditions to control the provider practice and measure the best practices to satisfy and improve the health outcomes. Social network analysis (SNA) concentrates on evaluating the relation among individuals, who are attached by one or more knot of interdependency, like friendship, love, trust, cooperation, or communication. Social network analysis can provide imminent into evaluating and understanding the specialized networks of communication and, hence, developing effective interventions in the network to enhance the performance of the provider and eventually, the outcomes related to health [12]. The diagrammatic representation of SNA is shown in Figure 1.1.

      For illustration, let us consider that the application of online social network in analyzing the contagious diseases originated with the biological pathogens, such as influenza, chickenpox, measles, and the sexually spread viruses that transfer from one person to another [13–15].
