AN INTRODUCTION

INTRODUCTION
• Social Network Analysis (SNA) is an approach/tool that enables us to examine and understand the connections between people/organisations/etc.
• SNA is derived from both sociology and mathematics, and can be explained as the use of network theory to analyse social networks
INTRODUCTION
• It focuses on the connections that drive certain phenomenon that involve a network of human players
• In other words, SNA helps us to understand how relationships form, what kinds of relational structures emerge from the building blocks of individual relationships, and what, if any, are the impacts of these relationships.
NODES AND TIES
• Social network analysis views social relationships in terms of network theory consisting of nodes (actors, vertices) and ties (also called edges, links, or connections).
• Nodes are the individual actors within the networks, and ties are the relationships between the actors.
• There can be many kinds of ties between the nodes.
NODES AND TIES• In its simplest form, a social network is a map of
specified ties, such as friendship, between the nodes being studied.
• Nodes are the individual actors within the networks, and ties are the relationships between the actors.
Ties
Nodes
• Nodes / Actors / Vertices− People− Teams− Organizations− Etc.
• Ties / Links / Edges Any relationships including:− Friendship− Family− Communication− Etc.
APPLICATION of SNA
SNA can be used for research in a number of fields including:
• Sociology – crime detection, formation of gangs etc.
• Epidemiology – spread of diseases such as HIV/AIDS, etc.
• Economics – social capital, framework for understanding international trade, etc.
• Management – change management, how an organization is mapped out, etc.
• Information Sciences – scientific collaborations, trend analysis, etc.
