Snowballing of references
Snowballing uses the references of the articles you have found together with citations of those references by others to help you find more references that might be relevant to your research.
Nils Jörgensen has built a tool for "Automatic snowballing using Semantic Scholar and Zotero web APIs", see https://gits-15.sys.kth.se/nilsjor/zotero-s2-api
