Evolution of Author's Topic in Authorship Network

There may be several reasons why people publish together. Above all, the fact that the authors share common professional interests is the main reason. In our research we work with the DBLP dataset which contains the basic bibliographic information of publications from the computer science field. These data are freely available and contain highly relevant information about publication activity from the period of nearly fifty years, even though they are not complete. One of the goals of our research is to analyze and visualize the evolution of authors and co-authorship from the point of view of research topics. We present the results of our research in this paper. One of the results is also visualization in our online FORCOA.NET system.
