Algorithm 4

Calculation of the semantic similarity.

Input:Topic(user) distribution matrix of the text: Matrix1, Matrix2

Output:Semantic similarity: Semantic_Similarity

1: for all , , = Matrix1, = Matrix2, do

2: get D_KL(p, q) by formula (3)

3: end for

4: get D(p, q) from D_KL(p, q) by formula (5)

5: Semantic_Similarity = 1- D(p, q)

6: returnSemantic_Similarity
