Generation of context-informative co-citation graphs

A system comprising a plurality of components that are executable by a processor, the components comprising:

• a receiver component that receives input from a user pertaining to a first research document;
• and
• a co-citation graph generator component that generates a co-citation graph that visually indicates a relationship between the first research document and a second research document based at least in part upon a number of other research documents that include citations to both the first research document and the second research document, wherein the co-citation graph further comprises at least a portion of a sentence from a third research document, wherein the sentence includes a citation to at least one of the first research document or the second research document.

A computer-readable medium comprising instructions that, when executed by a processor, cause the processor to perform acts comprising:

• receiving a query pertaining to a first research document from a user, wherein the first research document is co-cited with a second research document by a third research document;
• responsive to receiving the query, executing a search over a data repository that comprises data that is indicative of citations amongst research documents;
• based at least in part upon the search, causing a co-citation graph to be displayed on a display screen of a computing device, wherein the co-citation graph comprises a first node that is representative of the first research document, a second node that is representative of the second research document, a third node that is representative of the third research document, a first edge that couples the first node and the third node that visually indicates that the third research document comprises a first citation to the first research document, a second edge that couples the second node and the third node that visually indicates that the third research document comprises a second citation to the second research document, and at least a portion of a sentence that includes the first citation in the third research document to the first research document.
