Figure 1
The figure is organized vertically into four major sections: “Data Collection”, “Text Pre-Processing”, “Bibliometric Analysis”, and “Analysis of S D G Mentions”. Each section contains labeled boxes describing the flow of steps. Under “Data Collection”, a horizontal sequence of arrow-shaped stages displays four phases: “Identification”, “Screening”, “Eligibility”, and “Included”. Beneath these stages, corresponding process boxes show the movement of documents through the review pipeline: Under “Identification”, a box states: “Total records identified through W O S database: Sustainable Development Goal and Tourism (n equals 334)”. Under “Screening”, a box labeled “Total documents searches (n equals 334)” branches downward to a smaller box labeled “Duplicate documents (n equals 8)”. Under “Eligibility”, a box labeled “Documents assessed for eligibility (n equals 326)” branches downward to a box labeled: “Documents omitted due to exclusion criteria: (a) not specifically about tourism; (b) studied how the tourism sector was affected by climate change or some concrete action (n equals 131)”. Under “Included”, a final box on the right states: “Documents included (n equals 195)”. Below this, the section titled “Text Pre-Processing” contains a single wide box labeled “Cleaning and unification of text”. The next section, “Bibliometric Analysis”, contains two boxes: The left box is labeled “Descriptive analysis and bibliometric indicators”. The right box is labeled “Analysis of knowledge structures”, containing three types of analysis: “Conceptual analysis: keyword trends and co-occurrence, strategic diagram”, “Intellectual analysis: author co-citation, historiography”, and “Social analysis: co-authorship networks”. The final section, “Analysis of S D G Mentions”, contains two process descriptions: “Identification of mentions to specific S D Gs in title, keywords or abstracts” and “Identification of associated targets with specific S D Gs using text mining techniques and a set of keywords”.Data collection and analysis process.
