This simple webpage helps to create testdata for Microsofts Recommendation API. The Recommendation API expects an articles file (or catalog file) and an usage file which contains all clicks, purchases etc. that are used to get recommendations. The creation of the usage file is annoying if you do it in a CSV file. Therefore I build this simple webpage that allows you to add users and articles. Then you can select an user and click on the articles. Each click will create a new usage entry. The articles and usage data can then be exported as CSV file.
The data is stored in your browser cache so you can refresh the page and the data is still there. If you want to reset the data, then you can find cleanup buttons at the bottom of the page.
