Citation graph

In information science and bibliometrics, a citation graph is a directed graph in which each vertex represents an academic publication such as a journal article and in which each edge represents a citation from one publication to another.

The citation graph may be used in citation analysis as the basis for calculating other measures of scientific impact such as the h-index, and for studying the structure and development of different fields of academic inquiry.

Actual construction of citation graphs requires record linkage of the citations in a document to their cited document since the naming format has many variations.
