This lecture: Basic graph theory language and concepts for describing and measuring networks. I Next week: more advanced concepts and applications. E.g., Google’s PageRank algorithm, which ranks webpages by “importance” based on their position in the Web network.

Graph theory helps model, analyze, and understand social networks. By using graphs, we can find hidden patterns, identify important people, detect groups, and study how information spreads. Graph theory is great for modeling social networks because it can easily represent the connections between people. Here is why it is helpful −.

Jun 23, 2021 · Network Graph – Let’s make two graphs comparing users that joined in 2005 and 2015 using the igraph package in R. What will a difference in 10 years make? It takes a very long time to make network graphs, so we will limit our subset to 100k nodes and create subgraphs of the user with the maximum number of degrees.

graph structures: social networks, in which nodes are people or groups of people, and edges represent some kind of social interaction; and information networks, in which the nodes are information resources such as Web pages or documents, and edges represent logical

Aug 28, 2023 · Graph database systems like Apache AGE and Neo4j leverage the principles of graph theory to store, manage, and query complex relationships efficiently. Graph algorithms breathe life into social networks, enabling platforms to understand user behavior, optimize recommendations, and provide meaningful experiences.

provides an overview of graph theory concepts and algorithms commonly used in social network analysis. It discusses how these tools can be applied to understand the structure and dynamics of social networks,

Jun 18, 2024 · By utilizing different types of graphs, SNA can provide deep insights into how individuals and groups interact, how information flows, and how social structures are formed and evolved.

In the last twenty-five years or so social scientists from several disciplines have made increasing use of graphs and other topological constructs for representing patterns of social relations.

What is a Graph? - Can you draw one? - How does your graph represent: - the whole data set? - an individual data point? - the relation between two points? - What do all graphs attempt to convey? RELATIONSHIPS

Nov 6, 2024 · In this article, we explore two key concepts in graph theory: Social Network Analysis (SNA) and Graph Traversal Algorithms, both of which are crucial for analyzing and navigating...
