Automatic Free Text Answer Evaluation using Knowledge Network

The recent developments in the field of Information and Communication Technology (ICT) has resulted in a major paradigm shift in pedagogy and teaching learning. No longer restricted to the four walls of a classroom, ubiquitous learning is the current trend and universities are gearing up for larger intakes. In the wake of such an upsurge in volume, automatic evaluation of student answers is the need of the hour. The limitations of close ended questions notwithstanding, the popularity of such types are on the rise due to implementation ease. This paper presents a technique to evaluate free text answers of students which will augment and popularize the use of open ended questions for evaluation in online learning.
