Online Social Networks: Human Cognitive Constraints in Facebook and Twitter Personal Graphs
About this ebook
As the availability of digital communication data generated by social media is revolutionizing the field of social networks analysis, the text discusses the use of large- scale datasets to study the structural properties of online ego networks, to compare them with the properties of general human social networks, and to highlight additional properties.
Users will find the data collected and conclusions drawn useful during design or research service initiatives that involve online and mobile social network environments.
- Provides an analysis of the structural properties of ego networks in online social networks
- Presents quantitative evidence of the Dunbar’s number in online environments
- Discusses original structural and dynamic properties of human social network through OSN analysis
