Amazon Musical Instrument Reviews with 5-Core Filtering, 2018-2023

A sampled subset of Amazon Reviews from the Musical Instruments category, filtered for a recommendation system project. The data covers reviews from January 2018 to September 2023 and was processed with iterative 5-core filtering to ensure users and items have at least five interactions. It was created by oyku-tugana and includes a held-out test set of 5000 users for cold-start evaluation.

Use Cases

• Train collaborative filtering models based on user-item interaction data.
• Evaluate cold-start recommendation algorithms using the held-out test set of 5000 users.
• Analyze review patterns and user engagement for musical instruments over a five-year period.

Strengths

• Time-filtered to a specific five-year period from 2018-01-01 to 2023-09-12.
• Processed with iterative 5-core filtering to ensure dense user-item interactions.
• Includes a dedicated cold-start test set of 5000 users with 1-2 reviews.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
