Map of scientific research on Communication in Spain: study fronts and rankings of authors, publications and institutions

This work presents a current map of scientific research on Communication in Spain, identifying both the research fronts of the publications with the greatest impact over the last three years (2019–2021) and the authors who led such work and their universities of reference. The original methodology applied herein focuses on an analysis of the cited authors. After a careful selection process, we work with a corpus of more than 800 articles, using Scopus and the VOSviewer software to generate a co-referencing map and throw light on the structure of the Communication field. On the basis of that analysis, we identify nine thematic clusters, with a particular grouping structure, leading authors, and relationships around fields of study such as communication, democracy and power, audiences and media consumption, the media industry, journalistic practice, fact checking and disinformation, journalistic innovation, and SEO journalism. The ranking of cited authors, where Ramón Salaverría and Rasmus K. Nielsen hold equal first position and the Chilean Claudia Mellado is the only woman at the head of a strong group, is put into context by analyzing their scientific production and the normalized impact in Communication of their institutions. The comparative analysis reveals the elite Spanish authors in Communication (Xosé López-García, Ignacio Aguaded, Andreu Casero-Ripollés, Lluís Codina, and Ramón Salaverría) and shows how universities in Madrid maintain their importance in terms of production but that those in Catalunya have the lead in terms of impact. The research is completed with a map of keyword co-occurrence that confirms the barrage of studies around the Covid crisis and the parallel and growing number of hoaxes (fakes). The research confirms the relevance of and opportunity to apply scientometric techniques to the Communication field

Visualizing Business Ecosystems: Applying a Collaborative Modelling Process in Two Case Studies

Business ecosystems are increasingly gaining relevance in research and practice. Because business ecosystems progressively change, enterprises are interested in analysing their ecosystem, to identify and address such changes. In order to gain a comprehensive picture of the business ecosystem, various stakeholders of the enterprise should be involved in the analysis process. We propose a collaborative approach to model and visualize the business ecosystem and we validate four central roles in the modelling process. The process consists of six steps, namely the definition of the business ecosystem focus, instantiation of the model, data collection, provision of tailored visualizations, collecting feedback and adapting the models, and using the visualization ‘to tell a story’. In this paper, we report case studies of two companies that have instantiated ecosystem models

Mapping Twitter Topic Networks: From Polarized Crowds to Community Clusters

Conversations on Twitter create networks with identifiable contours as people reply to and mention one another in their tweets. These conversational structures differ, depending on the subject and the people driving the conversation. Six structures are regularly observed: divided, unified, fragmented, clustered, and inward and outward hub and spoke structures. These are created as individuals choose whom to reply to or mention in their Twitter messages and the structures tell a story about the nature of the conversatio
