Abstract: Criterion-based feedback allows users to provide useful information in a quick and easy to understand fashion. When information for an item is relayed to a user, the user is provided with the ability to provide feedback for any criteria relating to the item. In some embodiments, this feedback takes the form of a submission of a response to a question or statement pertaining to a criterion for the item. The user is able to create new responses if the existing responses do not adequately convey the feedback that the users wishes to submit. Further, a user can also submit entirely new questions and/or statements, along with corresponding new responses, that correspond to a criterion relating to the item. Such an approach provides flexibility for users to quickly and easily provide feedback on specific criteria that might be useful for other users viewing information for that item.
