Social shopping is a common occurrence on Web 2.0 sites. Reviews for products and services can be found everywhere. A review of a product can be found in a myriad of places, making it hard for the consumer to quickly make up his/her mind. ReviewCollage is a mobile application that serves as an aggregator (summarization system) of reviews for a product/service in one place; the user can then make a more informed decision just by doing one search for a product. The background works are fairly complex. The product is showcased by a study of eight participants who are looking at four hotel chains and trying to decide which one best fits their needs and wishes. This app provides comparisons between two entities using review comments that are generated by other users, making the comparison possible in a few short moments. While the proof of concept is there and focuses on the algorithm for producing the reports, the authors acknowledge that there is a lot to be done on the user interface side of things, and a study of user satisfaction will then be in order.
