Generally, to cite an academic document, there are a lot of writing style for different academic fields (e.g. APA, MLA, ISO 690, BibTex, and others). However, some documents that only have a generated DOI on ResearchGate, for instance technical report, article (data) and poster, seem worthy of scholarly citation but have not a full reference to cite it in a suitable way. How best should a person go about citing a document from a ResearchGate publication in an academic paper he or she is writing? DOI is not sufficient for writing a full reference. How do we download an appropriate and a complete reference to cite such paper only exists in ResearchGate (do not exist in Google Scholar)?
