This collection of MS Excel sheets contains tables (matrices) with Jaccard similarity values between research areas (RAs) and sustainable development goals (SDGs) as declared by the United Nations. The underlying taxonomy of RAs is based on one used in Web of Science (WoS). For each pair of RA1 x RA2 or SDG1 x SDG2 or SDG1 x RA1, the corresponding matrix entry is calculated as the quotient of the number of projects that have both items assigend (numerator) and the number of projects that have at least one of the items assigend (denominator). We interpret this Jaccard index as a measure of similarity or "overlap". The assignment of RAs to projects is based on the computational method of ESA ("Explicit Semantic Analysis"). For SDGs, also hand-coded assignments (SDG_Man) are available in addition to automatically calculated ESA-based values. In two versions, the RAs and SDGs included are limited to those that have at least been assigned to 5 projects overall (min5 version) or 10 projects overall (min10 version). The calculations are based on a sample of 208 projects extracted from the CS Track database.
