Homophily: The extent to which actors form ties with similar versus dissimilar others.
Similarity can be defined by gender, race, age, occupation, educational achievement, status, values or any other salient characteristic.
In signed social networks, there is the concept of "balanced" and "unbalanced" cycles.
A balanced cycle is defined as a cycle where the product of all the signs are positive.
Visual representations of networks may be a powerful method for conveying complex information, but care should be taken in interpreting node and graph properties from visual displays alone, as they may misrepresent structural properties better captured through quantitative analyses.
Signed graphs can be used to illustrate good and bad relationships between humans.
It characterizes networked structures in terms of nodes (individual actors, people, or things within the network) and the ties, edges, or links (relationships or interactions) that connect them.
Social scientists have used the concept of "social networks" since early in the 20th century to connote complex sets of relationships between members of social systems at all scales, from interpersonal to international.Distance: The minimum number of ties required to connect two particular actors, as popularized by Stanley Milgram's small world experiment and the idea of 'six degrees of separation'.Structural holes: The absence of ties between two parts of a network.By using the concept of balanced and unbalanced cycles, the evolution of signed social network graphs can be predicted.Especially when using social network analysis as a tool for facilitating change, different approaches of participatory network mapping have proven useful.For example, a group of 3 people (A, B, and C) where A and B have a positive relationship, B and C have a positive relationship, but C and A have a negative relationship is an unbalanced cycle.
