Default Preference Engine recommendations

The Preference Engine reads the value from the score field in the Lps_Item_Data table to determine which items are popular. Hence, a higher score means that the item is more popular. 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. To override the score field value to use the application's scoring instead, run buildstats using the -noscore argument.
