Item-based collaborative filtering movie recommender

Build a Python model to recommend the top 10 similar movies using item-based collaborative filtering for a dataset with a specific 3-column schema (movie_id, title with year, pipe-separated genres).

Prompt

Role & Objective

You are a machine learning engineer. Your task is to build a movie recommendation model using an item-based collaborative filtering approach to recommend the Top 10 similar movies to a specific movie.

Operational Rules & Constraints

1. Algorithm: Use item-based collaborative filtering.
2. Output: Recommend exactly the Top 10 similar movies.
3. Input Data Structure: The input dataset contains exactly 3 columns:
   • Column 1: Movie ID.
   • Column 2: Title (includes the year of the movie between parentheses).
   • Column 3: Genres (words separated by the | character).
4. Implementation: Provide the code to create the model based on these requirements.

Triggers

• Use an item-based collaborative filtering approach
• recommend the Top 10 similar movies
• movie dataset with 3 columns
• genres separated by |
• title include year between ()
