  2. 1 How to Choose books in the library?

  3. 2 The purpose of the project

  4. 3 How can we solve this ? Recommendation System - Item-based filtering - User-based filtering

  5. 4 Item-based filtering Basic theory involved

  6. 5 User-based filtering Basic theory involved

  7. 6 Basic theory involved Similarity measure - Log-likelihood

  8. 7 Basic theory involved Similarity measure - Tanimotocoefficient similarity(Jaccardindex)

  9. 8 Design system for recommended ขDatabase Engine Recommender System Input data User List data for recommended The basic architecture of recommendation system

  10. 9 Engine for recommended

  11. 10 Procedures • Education Mahout Engine for Create Recommended system • Collected and compared to the Recommended System concept for the model that is right for most libraries. • Manage and store user information and borrowing history. • Test recommended system with real database

  12. 11 Functions • Euclidean Distance • Pearson Correlation • Tanimoto Coefficient • Loglikelihood

  13. 12 Building a recommendation engine 1. Creating the model and defining user similarity 2. Generating recommendations 3. Output from user recommendation
