A Crowd-Sourcing Mobile Platform for Textbook Selling and Exchange Using Information Retrieval

Book selling and exchange is very popular among students at campus, especially at the beginning of each semester, which can save students’ expense on text books. Generally, a used book may be only worth one third or half of the original price or even less. However, existing book selling platforms have various issues in practice, such as not user-friendly, not efficient, or not widely used among students. In this paper, we develop a new book selling and exchange platform, which facilitates the distribution of book selling information and the communication between sellers and buyers. This application can be easily used on smartphone after it is properly downloaded and installed from app store
