Default Preference Engine recommendations

When buildstats runs, it updates the score field to the average rating for that item; it generates this value based on the rating set defined in the db.applic.rating.source parameter. To get reliable default recommendations, run the buildstats utility on a regular basis. By default, the installer sets buildstats to run once a day. Some applications use their own business logic to assign the score to items. If you want to override the score field value to use your application's scoring instead, run buildstats using the -noscore argument.
