Descriptive Statistics * The relevant 'universe' of the literature consists of 2,563 references identified in the Web of Science citation database (see Table 1), most of which are published in refereed journals (see Table 2). The literature review covers the period between January 1, 1990, and May 26, 2021. * The overall number of documents in our sample is 2,563 (see Table 1). This number is the cumulative result of each year, and we can observe a significant rise in the number of documents per year. The average citations per document are 12.6 but have evolved through time. * The number of articles dominates the sample for the overall period (see Table 2) with 1,414 occurrences, followed by 976 proceedings papers. --- ### Descriptive Statistics <div class="figure" style="text-align: center"> <img src="./figures/figure1.png" alt="Articles count through time" width="50%" /> <p class="caption">Articles count through time</p> </div> --- .panelset[ .panel[.panel-name[Overall] <table class=" lightable-classic" style='font-family: "Arial Narrow", "Source Sans Pro", sans-serif;

Keywords' co-occurrences --- ### Keyword co-occurrences networks - Co-word networks show the conceptual structure, that uncovers links between concepts through term co-occurences. - Conceptual structure is often used to understand the topics covered by scholars (so-called research front) and identify what are the most important and the most recent issues. - Dividing the whole timespan in

It shows the structure of a specific field through the linkages between nodes (e.g. authors, papers, journal), while the edges can be differently interpreted depending on the network type, that are namely co-citation, direct citation, bibliographic coupling. --- ### Articles .panelset[ .panel[.panel-name[Top Manuscripts] <div style="border: 1px solid #ddd; padding: 0px; overflow-y: scroll;
