It would seem that in order to compare the offers of several stores in the book industry it is sufficient to read the ISBN or EAN number from the offer correctly. In reality, however, most often:
· the monitored store does not provide EAN numbers on its website
· different editions of the book can be found under the same EAN
· the book and the e-book have the same EAN, although these are completely different titles of different authors
Therefore, in order to properly catalog such a large number of products, we have developed algorithms that are based primarily on the analysis of the title, author, release information, and cover image. This gives us high-quality specifications.
In addition to information about the price and availability of products, we prepare specific reports for our clients, where we can include additional markings. An example is whether “the book is on the best-sellers list", or whether a "pre-sale" is offered
