Assessment of Answers: Online Subjective Examination

Question answering is a specified form of information retrieval. Our work comes under closed domain question answering. We are working on assessment of answer for online subjective examination. Examination and evaluation are part of every course module so are even in online examination, objective based examination are already available but subjective examination are in need of time as subjective assessment is considered as best way of evaluation of ones subject understanding & knowledge. In our paper we have discussed two issues related to the answer method i.e. length & paraphrasing. And have obtained a pattern extraction by creating a sequence for a given answer. Our system has a centralized file system which includes the reference material as well as the model answer for questions. These are used for matching and evaluating a candidate’s answer. For every correct answer a confidence factor of being positive is assigned when the required selective pattern of candidates answer matches with the model answer.
