- 8. Methodology •Tools and Technologies Used • Algorithms
- 9. Tools & Technologies Used
- 10. Algorithm •Collaborative Filtering ▫ Nearest-Neighbor ▫ Association Rules ▫ Matrix Factorization Model
- 11. Collaborative Filtering • Widely-used recommendation approach • Prediction the utility of items for a user ▫ Matrix Factorization Model ▫ Association rules ▫ Nearest-Neighbor
- 12. Nearest-Neighbor • Memory-based approach • Utilizes the entire user-item • Approach includes ▫ User-based methods ▫ Item-based methods
- 13. Association rules • Each transaction for association rule mining is the set of items bought by a particular user. •We can find item association rules, e.g., visit_X, visit_Y -> visit_Z
- 14. Matrix Factorization Model • Map both users and items ȓ푢푖= 푞푖 푇푝푢 (1) • 푞푖 & 푝푢 are the vectors of item and users ȓ푢푖 is rating item ‘i‘ • Factor vectors (푝푢 and 푞푖 ), minimizes the regularized squared error on the set of known ratings: 푚푖푛 푞∗, 푝∗ (푢,푖)∈푘 (푟푢푖 − 푞푖 푇푝푢)2+휆(||푞푖 ||2 + ||푝푢||2) (2)
- 15. Implementation • Data Collection • Implementing Recommendation • Stakeholder Analysis • Market For Recommendation System
- 16. Data Collection • Source: ▫ Nepal Tourism Board ▫ Ministry of Tourism, Culture and Civil Aviation

- 22. Future Enhancements contd.. • User generated content and social networking services •Multiple days tour planning • Intelligent UI
- 23. Output : Home Page (Guest User)
- 24. Output : Home Page (Registered User) - Recommendation
- 25. Output : Search
- 26. Output : Age-Sex Based Visualization
- 27. Output : Nationality based Visualization
