    • Social network – online social structure made of nodes which are individuals
    • Folksonomy - collaboratively generated tags that categorize Web content
    • Hackability / reuseability – content viewed in one online location but created / hosted elsewhere; components of a mashup

  5. Definitions (con’t)
    • Ratings – Content valuation based on explicit (member provided) and implicit (centrality eigenvector) scores
