Social Networking Analysis And Mining Terminology 101

Here are some Social Networking terms that I found interesting:

Connections

• Homophily:  homo=similar, phily=affection for.  This is the extent to which actors (people, inviduals) form ties with similar versus dissimilar others.  Common measures of similarity are:  gender, race, language, age, occupation, education level, income level etc.
• Multiplexity:  how are two entities related to each other.  multi= many, plexity = connected-ness.  For example, Raj and Suman working together and also being bachpan friends would entail a multiplexity of 2
• Mutuality / Reciprocity:  this is easy.  If Peter is a friend of Jack's, does Jack also consider Peter a friend?  Is it one way - in which direction, or both ways?
• Transitivity:  
• Network Closure:  
• Propinquity:
