As part of "Online Data Collection and Management" (taught at Tilburg University, Fall 2021), students collected publicly available datasets for use in academic research projects. With this repository, I am sharing (a) the documentation of these data sets, and (b) associated Python source code that led to the collection of the data. This repository does not contain any of the collected datasets. The data consists of six data collections: airlinequality.com (airline reviews) untappd.com (craft beer) GitHub.com (search) goodreads.com (reading behavior) Huizenzoeker.nl (housing market in The Netherlands) Reddit API (social media) Course website: https://odcm.hannesdatta.com.
