Novel Recommendation System for Tourist Spots Based on Hierarchical Sampling Statistics and SVD++

Algorithm 3

A novel recommendation system for tourist spots.

Input: Questionnaire results T, Users’ rating matrix R

Output: Hybrid recommendation list

1. Generate the recommendation list using Algorithm 1.

2. Generate the recommendation list using Algorithm 2.

3. The mix merge method is used to generate the recommendation list .

4. Compute the precision, recall, and F1 values (Equations (21)–(24), respectively) of the hybrid

recommendation system.
