In Online Classifieds, buyers want to find ads that are relevant for them. In order to help our users do that, we at OLX want to be able to show them those ads by predicting the chance of any particular user of contacting the seller of any particular ads
We challenge you to predict the ads that any particular buyer will contact for the first time in the next 7 days grouped by category, within the limited scope of users that are only browsing and not searching. We will provide you with a training dataset containing the behaviour of a sample of users until a specific day. Also, the detailed information of all the ads available on that day and the information about the ones the users interacted with.
