Description

The aim here is to provide some easy-to-use machinery to enable the usage of the new Cooccurrence Analysis code from MAHOUT-1464 with datasets represented as follows in a CSV file with the schema timestamp, userId, itemId, action, e.g.

timestamp1, userIdString1, itemIdString1, “view"
timestamp2, userIdString2, itemIdString1, “like"
