Glossary
- Online Social Network :
-
An online platform to which users can subscribe that allows users to create their own profiles and to interconnect each other, fostering the creation of a virtual social network of ties and social relations among people that share interests, activities, or real-life connections
- Community Structure :
-
Large (online) social networks are known to exhibit a community structure: nodes can be separated and grouped into (possibly overlapping) sets so that each group is densely interconnected internally and loosely connected with others
- Modularity :
-
The modularity function Q has been introduced to determine the quality of the grouping structure or clustering of a given network G = (n, m) with n nodes and medges. A network clustering is considered well founded if nodes assigned to the same cluster are tightly interconnected among each other and loosely interconnected with those assigned to other clusters. Such type of networks exhibits a so-called community...
