I have submitted some papers on research gate as conference papers, but intend to review and resubmit as full length papers for publication. Can this be possible?
Conference papers can resubmitted for publication in a journal provided that 1) they are fully adapted to the written conventions of a journal, and depending on the journal 2) you acknowledge that it has been presented at a conference, 3) it has not been published in a proceedings volume. In any case, it is always wise to contact the editor.
