A Configurable Course Feedback System with Sentiment Polarity Detector

This paper presents experimental design for opinion extractor from free-form texts and its deployment in configurable course feedback system. A configurable system is implemented through which interactive course feedback forms can be generated. The feedback-form contains close-ended questions and also text boxes to enter free-form responses. The algorithmic formulation has been designed to compute opinion polarities from the free-form text responses entered by the users. The system produces a comprehensive output for the use of teachers and/or academic administrators. The deployed system is not only easy to use and configurable but also allows users to choose the way they wish to respond (either only as free-form text responses or free-form text responses with answers to some close ended questions). The system has been evaluated on reviews collected from ratemyprofessor website.
