Query: On the use of topological features and hierarchical characterization for
  disambiguating names in collaborative networks   Many features of complex systems can now be unveiled by applying statistical
physics methods to treat them as social networks. The power of the analysis may
be limited, however, by the presence of ambiguity in names, e.g., caused by
homonymy in collaborative networks. In this paper we show that the ability to
distinguish between homonymous authors is enhanced when longer-distance
connections are considered, rather than looking at only the immediate neighbors
of a node in the collaborative network. Optimized results were obtained upon
using the 3rd hierarchy in connections. Furthermore, reasonable distinction
among authors could also be achieved upon using pattern recognition strategies
for the data generated from the topology of the collaborative network. These
results were obtained with a network from papers in the arXiv repository, into
which homonymy was deliberately introduced to test the methods with a
controlled, reliable dataset. In all cases, several methods of supervised and
unsupervised machine learning were used, leading to the same overall results.
The suitability of using deeper hierarchies and network topology was confirmed
with a real database of movie actors, with the additional finding that the
distinguishing ability can be further enhanced by combining topology features
and long-range connections in the collaborative network.
