Described herein are technologies pertaining to generating co-citation graphs. A context-informative co-citation graph includes a first node that represents a first research document, a second node that represents a second research document, and a third node that represents a third research document that includes a citation to both the first research document and the second research document. The context-informative co-citation graph also includes a first edge that couples the first node and the third node, and a second edge that couples the second node and the third node. The two edges visually indicate that the first research document and the second research document are co-cited by the third research document. The context-informative co-citation graph further includes at least a portion of a sentence in the third research document that includes a citation to at least one of the first research document or the second research document.
