Systematic Literature Review
We present in Table 4 the list of journals where the selected relevant studies were published. The table contains the assigned journal identifier, the journal name, the journal’s country, the impact factor (IF) in the JCR and SJR and the related study ID. We considered it important to display the JCR IF and the SJR, since they are indicators related to the quality of the research according to the number of citations of the published studies and their importance in the scientific research.
Conferences
We present in Table 5 the details of the conferences where some relevant studies were presented. The assigned conference identifier, the conference name, the core ranking and the respective studies identifiers are listed. We used the conference ranking Computing Research and Education Association of Australasia (CORE), 2018. This ranking was created by an association of computer science departments from universities in Australia and New Zealand. This Association provides conference rankings in the computing disciplines based on a mix of indicators, including citation rates, paper submission and acceptance rates. The rankings range are represented by the letters A*, A, B and C—A* being the best and C the worst.
Through the performed analysis, research question RQ1 is answered in significant detail. In order to answer the next two research questions, each of the selected articles deemed as relevant were analyzed, after a full reading of each of them.
The objective of this section is to answer the second research question, RQ2. To comply with this goal, we rely on the concept matrix [58] compiled in Appendix A. There, we synthesize the literature about each one of the 36 articles that comprise the final research corpus. Next, each of the key concepts that we have covered in this SLR will be described. Mainly, three domains are analyzed:
