Visual inspection of networks is a powerful tool in exploratory analysis of social networks. However, visualization of graphs has inherent problems that may result in misleading visualizations. This chapter first introduces basic theory behind these inherent problems. Then it introduces features of common layout algorithms used in visualization. Through applied examples, the chapter explores the use of layout parameters to obtain visualizations appropriate for the research focus.
The emergence of social networks has revolutionized the way people communicate and share information. Consequently, it becomes important to analyze the role of these models of collaboration and innovation through social networks in the strategic vision of the responsibility of marketing and communication in tourism industries, mainly the role of Facebook in e-business actions.

The present investigation studies the use of some tools in the discourse informative of the covers of the newspaper to explain the causes and consequences of the State of Alarm during the first week of confinement. As a previous step, a survey was carried out on social networks to capture opinion trends regarding the information disseminated by the media during the confinement The aim has been developed from the corpus created with 132 informative pieces (texts and images) published in the four newspaper headlines in paper with more diffusion according to the data published by the EGM. To delimit the period of study (14 of March-22 of March of 2020) we took like reference two facts that had special relevance in the crisis propitiate by the coronavirus: The statement of the State of Alarm and the overcoming the psychological barrier of the first 1000 died in Spain by the pandemic.

With the data obtained, realized and no exploratory analysis to determine the use of the following journalistic resources in the covers: the informative sources, thematic, informative gender and accompaniment of photographs or other graphic elements.
Because of the complexity of the actors and the relationships between them, social networks are always represented by graphs. This structure makes it possible to analyze the effectiveness of the network for the social actors who are there. This work presents a social network analysis approach that focused on processing Facebook pages and users who react to posts to infer influential people. In our study, we are particularly interested in studying the relationships between the posts of the page, and the reactions of fans (users) towards these posts. The topics covered include data crawling, graph modeling, and exploratory analysis using statistical tools and machine learning algorithms. We seek to detect influential people in the sense that the influence of a Facebook user lies in their ability to transmit and disseminate information. Once determined, these users have an impact on business for a specific brand. The proposed exploratory analysis has shown that the network structure and its properties have important implications for the outcome of interest.
Social networks have become a means of interaction between companies or organizations and consumers. However, few studies have dealt with the use of tangible and intangible attributes on social networks of manufacturing companies. This work deepens the concept of brand equity of European manufacturing companies through the analysis of brand engagement and electronic word-of mouth (eWOM) generated by social media posts. Firstly, tangible and intangible attributes have been identified on tweets. Secondly, it has been analysed if there is a link between tweets based on tangible and intangible attributes and number of likes (brand engagement) or retweets (eWOM). The multivariate analysis results show relationships between publications including the analysed attributes and brand equity. In contrast, eWOM is only related with tangible attributes. Conclusions are discussed.
