Background LikeMinds utilities

LikeMinds depends on two utilities to update the database:

sifter

This utility runs continuously to identify mentors for new users and recomputes the best set of mentors for existing users. The mentor set for a user may change as the sifter gathers more information about the user or the mentors.

buildstats

This utility runs once a day to update statistics for each item, such as the number of ratings or transactions, the average rating, the standard deviation in the average rating, and the default recommendation information.

These utilities are run from the LikeMinds utility servlet.

You must configure these utilities to run at appropriate times.
