What kind of interactions are reflected in the sessions training set?

Amazon KDD Cup '23: Multilingual Recommendation Ch
#1

Hi,

Looking at the session_training.csv, it has the following columns:

  • Previous items: Array of item IDs previously interacted with
  • Next item: Item ID of next item interacted with (after the previous items)
  • Locale

I couldn’t find any documentation on what an “interaction” is - is it a purchase? is it a click? Are all interactions the same, or are some of them different? This is important to know when building a model.

Thanks!

I have the same question. A clarification is needed.
