I'm looking for free datasets of product reviews. At minimum I need the following values for each record:

  • Rating (e.g. 2/5 stars, or 40%)
  • Product Name / Description (e.g. iPhone 5s)
  • Reviewer (e.g. Wired magazine)

Any additional values would be a bonus, such as:

  • Category (e.g. Smartphone)
  • Price
  • Date

I particularly want products reviewed by magazines/websites (i.e. journalists rather than the public) as I am investigating the skew of product reviews from a neutral source (e.g.is it more likely that a magazine will rate a product higher because it has to consider its income stream from advertising?). I am interested in reviews of ANYTHING, and would love to build a dataset from a diverse range of reviewers.

So far I have managed to scrape some reviews from websites and have datasets of album reviews, bike reviews and a small dataset of consumer tech reviews. This is quite a time-consuming process so it would be great if there was pre-existing datasets of this ilk.

    Not to be too discouraging but I think the only place you'll find something like this is as part of a curated data set that was created for similar research purposes as yours. Assuming you looked into if a similar project had been executed before, I dont think you'll find anything else except for: a) data sets from a single site such as Amazon/Google which will all be UGC (user generated content), b) have to screen scrape from either the product site (will be clearly biased) and/or from across the internet which may bring up copyright concerns. Good luck!
