Description of Selection and Cleaning

The following search query: CU (“GERMANY” AND “INDIA”) was used to retrieve the data from WoS. The data were retrieved from the year 1990 till the 30th of November 2022. A total of 36,999 records were retrieved against the employed query. For the present dataset, we retrieved only articles identical to those from WoS.

Our original dataset retrieved from WoS consisted of 36,999 entries. 33,319 entries possess a valid DOI, and 3,680 entries do not have a DOI. Therefore, we developed two approaches for retrieving desired data from the Openalex collection. Articles possessing a DOI were matched by DOI (dataset 1), and articles without DOI (dataset 2) were matched by article title and publication year.

Afterwards, DOIs in dataset 1 were additionally compared to the DOIs from the original WoS dataset, all inconsistencies were removed.

For dataset 2, authors were additionally checked. Authors’ surnames from dataset 2 and authors’ surnames from corresponding articles (matching by title and publication year) from the WoS dataset were compared. Only articles with matching publishing years, author surnames lists and titles were considered for the Openalex dataset. Following, dataset 1 and dataset 2 were combined into one final dataset (Openalex data).

Additionally, all duplicates (by article ID) were removed from the Openalex data. In the final step, we checked if all entries contained both German and Indian affiliations. Some inconsistencies with the WoS data were observed: 5,584 entries, which have both Indian and German affiliations in WoS had only one of the indicated above affiliations in the Openalex. These entries were removed from the final dataset. The final dataset resulted in 22,844 unique entries.
