Overlapping community detection in networks based on link partitioning and partitioning around medoids
, , , Plos One 2021 Vol. 16 No. 8 Article e0255717
In this paper, we present a new method for detecting overlapping communities in net- works with a predefined number of clusters called LPAM (Link Partitioning Around Medoids). The overlapping communities in the graph are obtained by detecting the disjoint communities in the associated line graph employing link partitioning and parti- tioning around medoids which are ...

Using network approach, we propose a new method of identifying key food exporters based on the long-range (LRIC) and short-range interaction indices (SRIC). These indices allow to detect several groups of economies with direct as well as indirect influence on the routes of different levels in the food network. ...

We construct a model to find the insecure countries in terms of food security using network analysis under the conditions of deep uncertainty. The conditions under deep uncertainty can be drought, flood, earthquakes, etc., which affect the supply and demand of food of the countries. Under such conditions which countries are more vulnerable has been ...

An empirical comparison of connectivity-based distances on a graph and their computational scalability
, , et al., Journal of Complex Networks 2022 Vol. 10 No. 1 Article cnac003
In this study, we compare distance measures with respect to their ability to capture vertex community structure and the scalability of their computation. Our goal is to find a distance measure which can be used in an aggregate pairwise minimization clustering scheme. The minimization should lead to subsets of vertices with high induced subgraph density. ...

Our study employs the network approach to the problem of international migration. During the last years, migration has attracted a lot of attention and has been examined from many points of view. However, very few studies considered it from the network perspective. The international migration can be represented as a network (or weighted directed graph) ...

Navigability, an ability to find a logarithmically short path between elements using only local information, is one of the most fascinating properties of real-life networks. However, the exact mechanism responsible for the formation of navigation properties remained unknown. We show that navigability can be achieved by using only two ingredients present in the majority of ...
