MIS 301 Exam 3
Social Network Analysis - correct answer ✔- study of how individuals divide
their energy between different social groups over time
- how do things link to each other?
- explains how nodes are connected to each other
- gives tools to quantify those connections between individual points often in
the visual format
- can find patterns in the forces that connect us together
- how is a person connected or disconnected


Networks - correct answer ✔- mapping of relationships
- can be URLs, people, groups, companies, orgs, etc.
- collection of points joined by lines
- "network" = "graph"


- nodes
- edges - correct answer ✔- nodes are what you're connecting
- 2 nodes are adjacent if they are connect by at least one edge
- edges are the links/lines connecting the nodes
- edges represent the presence of relationships


network element: edges
1. directed
2. undirected
3. edge attributes - correct answer ✔- direction is important
1. also called arcs; A -> B

, - A likes B, A gave a gift to B, A is B's child (B can't be A's child)
- B doesn't like A back; B doesn't give a gift to A


2. A <-> B or A - B (goes both ways)
- A and B like each other
- A and B are siblings (if one is your sibling, you are theirs)
- A and B are co authors


3. - weight (ex: frequency of communications- how often relationships happen)
- ranking (best friend, second best friend...)
- type (friend, relative, co-worker)


- Adjacency Matrices
1. Aij = 1
2. Aij = 0
3. Aii = 0
4. Aij = Aji - correct answer ✔- representing edges (who is adjacent to whom)
as a matrix
- much easier to look at it as a graph than a matrix
- matrix is filled with 0 and 1 to represent the connection
1. if node i has an edge adjacent to node j ( i -> j )
2. if node i does not have an edge to j
3. unless the network has self loops
4. if the network is undirected, or if i and j share a reciprocated edge ( i <-> j )
- left side of matrix has list of nodes and what other nodes it points to
- top part has list of nodes and what nodes point to it
