### Demographic Analysis  
Figure 2 presents the distribution of publication types for the primary studies. It shows that 50% (S3, S5, S6, S8, S9, S11, S12, S13, S14, S17, S22, S24, S25, and S28) of the related studies were presented and published at conferences, followed by 21.4% (S1, S2, S4, S7, S10, and S18) presented at workshops, 14.3% (S20, S21, S26, and S27) published in international journals, 3.6% (S16) presented at symposiums, 3.6% (S19) in scientific journals, 3.6% (S15) as a master's thesis, and 3.6% (S23) published in a scientific web repository. \begin{table}

Table 8: _Cont._On the other hand, Figure 3 shows that the demographic distribution of the primary studies spans 18 countries and 4 continents as follows (references have been omitted for readability, please refer to Figure 3 for country-specific references): Oceania with 7% (2 articles, two countries: New Zealand and Australia), Asia with 11% (3 articles, 2 countries: Bangladesh and China), America with 14% (3 articles, 2 countries: USA and Canada), and Europe with 68% (16 articles, 12 countries: including the Netherlands, Poland, and the UK). The data suggests that Europe has the highest concentration of publications with 66.7% of the studies, indicating a significant research focus on this continent compared to others like America, Asia, and Oceania, which have much lower representation. This disparity could be driven by various factors, such as the level of development in these countries, research funding, access to resources, or language barriers in publishing. The reader is encouraged to explore these variables in-depth, considering aspects such as publication impact, quality, and relevance within the field, as well as citation metrics.
