The theory of social balance, also called structural balance, is first proposed by Heider in
1940s, which is utilized to describe the potential social dynamics process. This theory is of …

Various types of social relationships, such as friends and foes, can be represented as
signed social networks (SNs) that contain both positive and negative links. Although many …

Several network embedding models have been developed for unsigned networks. However,
these models based on skip-gram cannot be applied to signed networks because they can …

The research works that investigate controversies on social media seek to answer questions
such as the following: Is the topic controversial? What opinions do the users hold? What is …

To detect communities in signed networks consisting of both positive and negative links, two
new evolutionary algorithms (EAs) and two new memetic algorithms (MAs) are proposed …

A wide range of data science problems can be modeled in terms of a graph (or network), eg,
social, sensor, communication, infrastructure, and biological networks. The nodes in a …

Research on network structural balance has been of great concern to scholars from diverse
fields. In this paper, a two-step approach is proposed for the first time to address the network …

In this paper, the authors consider both the nodes' opinions dynamics and signed network
edges' evolution. Simulated Annealing Algorithm is applied for searching the minimal global …

Clustering of like‐minded users is basically the goal of community detection (CD) in social
networks and many researchers have proposed different algorithms for the same. In signed …

Community detection is a fundamental task in the social network analysis field, which is
beneficial for many real-world applications such as recommendation systems and telephone …
