document: Extraction and mining of an academic social network This paper addresses several key issues in extraction and mining of an academic social network : 1 ) extraction of a researcher social network from the existing Web ; 2 ) integration of the publications from existing digital libraries ; 3 ) expertise search on a given topic ; and 4 ) association search between researchers . We developed a social network system , called ArnetMiner , based on proposed methods to the above problems . In total , 448,470 researcher profiles and 981,599 publications were extracted\/integrated after the system having been in operation for two years . The paper describes the architecture and main features of the system . It also briefly presents the experimental results of the proposed methods .
