Stage 1: Keyword Taxonomy and Selection
A comprehensive list of target keywords and their common synonyms was established to represent the core themes of each SDG. The official United Nations definitions and explanations were used to derive four to six primary key words for each SDG. From there, equivalent phrases and synonyms were included in the list to catch variations in terminology.
Example: For SDG 2 (Zero Hunger), ‘food justice’ was a primary keyword while related phrases such as ‘food security’ and ‘food access’ were included as additional synonyms.
