Abstract:
Using computer databases of scientific papers in physics, biomedical
research, and computer science, we have constructed networks of
collaboration between scientists in each of these disciplines. In these
networks two scientists are considered connected if they have coauthored one
or more papers together. We study a variety of statistical properties of our
networks, including numbers of papers written by authors, numbers of authors
per paper, numbers of collaborators that scientists have, existence and size
of a giant component of connected scientists, and degree of clustering in
the networks. We also highlight some apparent differences in collaboration
patterns between the subjects studied. In the following paper, we study a
number of measures of centrality and connectedness in the same networks.
