First of - thanks for this amazing dataset! It has been immensly useful.
How exactly did you scrape the data? Is it a complete set of all available amazon-reviews and items up to a specific cut-off date, or did you use specific criteria or sampling methods to compile it?
In the item metadata you also include the price of the product at the time of crawling. Is that the same time for all items in this dataset or does it differ from item to item?
- We aimed to collect all available reviews up to September 2023, prioritizing the completeness of each user’s review set. Our process involved first collecting user IDs, then collecting all reviews associated with each user. As a result, some items or reviews may be missing. Additionally, due to the time required for collection, some recent reviews may be absent -- even if posted before the cut-off date. Technical challenges, such as network issues and parsing errors, can also impact data completeness.
- Due to technical challenges, the timing for dumping product prices may vary by up to several months.
