Query: Multi-attribute community detection in International Trade Network   Understanding the structure of communities in a network has a great
importance in the economic analysis. Communities are indeed characterized by
specific properties, that are different from those of both the individual node
and the whole network, and they can affect various processes on the network. In
the International Trade Network, community detection aims to search sets of
countries (or of trade sectors) which have a high intra-cluster connectivity
and a low inter-cluster connectivity. In general, exchanges among countries
occur according to preferential economic relationships ranging over different
sectors. In this paper, we combine community detection with specific
topological indicators, such as centrality measures. As a result, a new
weighted network is constructed by the original one, in which weights are
determined taking into account all the topological indicators in a
multi-criteria approach. To solve the resulting Clique Partitioning Problem and
find homogeneous group of nations, we use a new fast algorithm, based on quick
descents to a local optimal solution. The analysis allows to cluster countries
by interconnections, economic power and intensity of trade, giving an important
overview on the international trade patterns.
