Analysis on Influential Functions in the Weighted Software Network

Algorithm 2

FunctionRank.

Input: node , childStr ()

Output: the NI of node //evaluate the importance of nodes

Process:

(01) Initialize NI() = 1, = 0.15

(02) if (childStr[] != null)

(03) outdegree = childStr.size ();

(04) for (each childStr [])

(05) if ( is equal )

(06) outdegree - -;

(07) else

(08) weighMap.put (,weight ());

(09) weigh += weight ();

(10)

(11)

(12) for (each childStr [])

(13) if ( is not equal )

(14) tempNI () += NI () weighMap.get ()/weigh;

(15)

(16)

(17)

(18) tempNI () = () (outdegree () + 1);

(19) NI () = tempNI ();
