Algorithm 2

AHP.

Function AHP{

Initialize

 𝑀: The number of nodes

 𝐼(𝑖): the value of influence about user 𝑖.

 𝑆(𝑖): the power of support about user 𝑖.

 𝐴(𝑖): the value of activity about user 𝑖.

 𝑤=(𝑤_𝐼,𝑤_𝑆,𝑤_𝐴).

 𝑖=1.

While (𝑖≤𝑀)

 AHP(𝑖)=𝑤_𝐼𝐼(𝑖)+𝑤_𝑆𝑆(𝑖)+𝑤_𝐴𝐴(𝑖).

 𝑖=𝑖+1.

Return

 The Top 𝑁 opinion leaders 𝑁=1%⋅𝑀.
