The link‐prediction problem for social networks
Tập 58 Số 7 - Trang 1019-1031 - 2007
AbstractGiven a snapshot of a social network, can we infer which new
interactions among its members are likely to occur in the near future? We
formalize this question as the link‐prediction problem, and we develop
approaches to link prediction based on measures for analyzing the “proximity” of
nodes in a network. Experiments on large coauthorship networks suggest that
information about future inte...

Data mining emotion in social network communication: Gender differences in MySpace
Tập 61 Số 1 - Trang 190-199 - 2010
AbstractDespite the rapid growth in social network sites and in data mining for

none has had social science goals. This article examines the extent to which
emotion is present in MySpace comments, using a combination of data mining and
content analysis, and exploring age and gender. A random sample of 819 public

How does publication pressure in modern‐day universities affect the intrinsic
and extrinsic rewards in science? By using a worldwide survey among demographers
in developed and developing countries, the authors show that the large majority
perceive the publication pressure as high, but more so in Anglo‐Saxon countries
and to a lesser extent in Western Europe. However, scholars see both the pros
(up...
