Abstract
The goal of our investigation is to construct an educational system, supporting lessons' evaluation by student initiatives. In this type, the question items created by many students also have similarities, therefore it is necessary to standardize these items by a certain method. However, if teachers depend only on manual operation, adjustment of an item will take huge cost. Then, we have prototyped cloud application based on LAMP (Linux, Apache, MySQL, and PHP) and R language. The application is characterized in calling the R Commands through PHP scripts. As a result of performance test, we have a few issues around the retrieval accuracy mainly based on the query expansion and/or latent semantic analysis, with no problem in an actual use however. Some techniques can also be applied to the development of the modules in LMS such as Moodle in the future.
