The study of networks has emerged in diverse disciplines as a means of analyzing complex relational data. The earliest known paper in this field is the famous [[Seven Bridges of Königsberg]] written by [[Leonhard Euler]] in 1736. Euler's mathematical description of vertices and edges was the foundation of [[graph theory]], a branch of mathematics that studies the properties of pairwise relations in a network structure. The field of [[graph theory]] continued to develop and found applications in chemistry (Sylvester, 1878).

网络研究作为分析复杂关系型数据的一种手段，在不同的学科中都有出现。在这个领域已知最早的论文是1736年欧拉（Leonhard Euler）写的著名的柯尼斯堡七桥问题（Seven Bridges of Königsberg）。欧拉对顶点和边的数学描述是[[图论]]的基础，这是一个研究网络结构中成对关系的性质的数学分支。图论的领域继续发展，并在化学中得到应用(Sylvester，1878)。
