Abstract: Using the DBLP computer science bibliography as raw data， the coauthor network of the computer and related fields was studied. By parsing the extracted xml metadata， the coauthor network topology was constructed， and the general parameters of the network topology were calculated. In addition， the statistical characteristics of a number of parameters were analyzed， which could be found that the DBLP coauthor network is a typical smallworld network yet with no obvious scalefree property. Different research cooperation modes were reflected by the topologies of center and bordering of the network， and there is no strong correlation of the kcore of the network with the scientist’s hindex. The development of complex network and the positioning of our lab in the computerrelated field at the academic level were finally discussed.

Key words: DBLP(database systems and logic programming), coauthor network, complex network, core, shrink, community
