In shopping websites such as amazon a product can have several reviews from customers who have already consumed that product. As reviews represent the customer experience with the product it may describe one or more aspects of the product. Considering a digital camera, for instance, a review may entail information about the battery life of the camera or talk about the display quality. When dealing with reviews it is thus important to understand what aspects the reviews talk about. So the main problem here is to identify the different aspects that are described in the reviews of a product. Once this is determined reviews talking about the same aspect can be clustered together, i.e. all reviews about the same aspect can be grouped together within the same bin. Note there might be reviews concerning with more than one aspect. In this case the review have to be clustered into the respective aspect clusters -- same copy of the review is assigned to several aspect clusters.
