Steps Action to be taken

  2. Select Get more movies from the menu.

  3. Click the To Lobby icon.

You can show all of the movies or just certain rated movies by selecting one of the ratings. You can look at the ratings of other movies by clicking Get More Movies. This demo allows you to rate movies. For more movies, type the name of a movie into the search panel to see if specific movies are stored in the database.

The LikeMinds collaborative filtering technology considers each user to be the center of their own preference cluster, instead of trying to find the best preordained preference category for every user, which is typical of profile-based approaches. LikeMinds recommendations can adapt to these changes much more quickly than aggregated, profile based techniques.

Run the following command if you see ERROR 42X05: Table 'FEEDBACK.XXXXX' does not exist in the error log:

ConfigEngine feedback-database -DInitializeFeedbackDB=true

To remove the application:

Run the following command from the profile_root/ConfigEngine:
