This 2010 article focuses on Social Network Analysis (SNA) and proposes a new generation of node centrality measures for weighted networks. The authors do this by building on previous research, which uses weights to operationalize tie strength between nodes within networks.
This 2012 article focuses on Social Network Analysis (SNA) and particularly the challenge of identifying central nodes within a given social network. The authors propose a new centrality measure for weighted networks based on the amoeboid algorithm, which is called Physarum centrality.
This 2010 post focuses on the distance between nodes within social networks and particularly those with disconnected components. Key node centrality is defined by the author as the inverse of farness, and in turn, the sum of distances to all other nodes within a given network structure.
This 2013 paper focuses on measuring relationship strength on Facebook based on user’s activities and profile information. The authors critique social network research focused on friendship networks.
This 2012 article focuses on the detection of hidden relationship structures in online social networks including the characteristics of relationship structures on Facebook. The authors argue that graphs fail to capture the finer qualities of online social network relationships.
This 2014 article proposes an estimation method for relationship strength in weighted social network graphs. The authors argue that their method can fully estimate the relationship strength between any two users in a social network, whether they are directly connected or not.
