  2. Outlines • Motivation • Objectives • Methodology • Experiments • Conclusions • Comments

  3. Motivation • Existing recommendation algorithms depend on single algorithm.

  4. Objectives • To overcome this limitation and to provide consistent and stable recommendationin social networks.

  5. Methodology-Framework

  6. Creation of initial candidate pool Methodology u → a → c u → a ↗ ↘c b

  7. Creation of initial candidate pool Methodology Application of component algorithm Number of followers Number of tweets Common follower u → a → c u → v ↗ ↘c PageRank a Profile matching
