*3.7. Keywords*

Both the mode and the median values for this criterion are on interval three to five keywords given by the authors per article in a majority of 36 articles, i.e., 60% of the total selected articles (see Figure 12). There are 21 articles between six to eight keywords. It seems worth noting that there is 1 article with 10 keywords and 2 articles without keywords.

We conclude that 10 keywords are perhaps too many, as they widen the analysis field too much rendering the interpretation unpractical.

The boxplot on Figure 13 shows the detailed outliers (0 and 10) that almost extrapolate the series, and the median, or second quartile, that stands on interval 3 to 5, on 4 to be precise.

A content analysis of the keywords was performed using the word cloud, shown in Figure 14. As we can see, the subject of this SLR is absolutely present in the selected articles, with both talent managemen<sup>t</sup> and EB—the basic concepts guiding our research—standing out. Additionally, interesting are the concepts standing out next—brand, recruitment, employee, human resources management—all of them considered key in our analysis. The word 'talent' alone also reveals a decisive weight in our content analysis. The words 'attraction' and 'retention' also entail a similar weight.

Another relevant aspect is the appearance of 'qualitative' with more weight than 'quantitative'; this is relevant because it matches the results obtained on the analysis of the methods used on the articles that compose the corpus of our SLR. This word cloud confirms in more than one aspect the bibliometric interpretation conducted on this research.

The keywords were also submitted to the VOSviewer software to map the correlations between them, thus allowing a view of the network nets between several bibliometric dimensions. In this particular case, we are able to understand that only 10 of all the keywords used by the authors in the analysed articles represent a stronger link (see Figure 15), meaning they appear simultaneously more often in the defined keywords.

Figure 15 highlights as expected the research criteria: talent managemen<sup>t</sup> and EB. The link between the concept of EB and both 'recruitment' and 'innovation' must be pointed out, emphasising that attraction is the dimension of talent managemen<sup>t</sup> mostly explored by EB. As the literature shows, though being in the market since 1996, EB is also an innovation factor [24], contributing to the notion that EB is an innovative tool used by talent managemen<sup>t</sup> concerning the dimension 'workers attraction'. It is also interesting to analyse that the word 'strategy' is related to the two concepts under analysis on the same level, as well as talent retention.

#### *3.8. Content Analysis*

In order to address the objectives of the present study, a content analysis of the selected articles was performed (see Table 2) concerning two aspects—on the one hand focusing on the main conclusions, and on the other hand, identifying the EB dimensions focused on each study.
