ECatalog is a database front-end, with two main features: 1. Use of preferences A preference-based approach, where the user is allowed to define the importance of each criterion. Then the items are ranked accordingly to his criteria. 2. Trade-off analysis A cooperative database approach, where the system "argues" with the user about his criteria. When there are no matching items, the system explains the minimal conflicting set and give some possible strong and weak relaxations about his criteria. This package also containts the software and the set-up details used for our User Study, comparing the use or not of the two previous features mentioned above.
