|CritiqueShop is an online platform for designing and evaluating e-commerce product search tools based on the critiquing technique. It provides a unified user interface so that the performances of different recommendation algorithms can be evaluated under the same condition. This system is developed with Java/AJAX (see Google web toolkit for the detail of this technology). For more information about this system, please see our publications.|
|A crucial element in consumer electronic commerce is a catalog tool that not only finds the product for the user, but also convinces him that he has made the best choice.
We have examined the performance of such tools on a variety of tasks involving selection and tradeoff. The studies clearly show that example-based search is comparable to ranked lists on simple tasks, but significantly reduces the error rate and search time when complex tradeoffs are involved. This shows that such tools are likely to be useful particularly for extending the scope of consumer e-commerce to more complex products.
|We have developed and implemented an online vacation planning prototype that helps users in the vacation packages selection process. Two algorithms were implemented, one for finding packages that satisfy user requirements, the other one for computing the list of values that the user can further select for each of the vacation attributes. Easy-to-understand visualizations are used for displaying the vacation attributes and the resulting vacation packages.|
|Travel products are complex, involving combining flights, car rental, and hotels. Applying our technology developed for general electronic catalogs, we have successfully implemented a travel planning system, enabling customers to view a large selection of flights, search specific trips using their personal criteria, and plan their trips integrating car rentals and hotel accommodations.|
