Fig 3.1: Architecture of the proposed system
4. Methodology
The system comprises of four modules and they are Login module, Information extraction module, Weighting module and Score Generation module.
1. Login Module:
The login module authenticates both the user and the admin. Once the authentication is done, the user and admin can perform their individual activities.
1.1. Admin Login:
The admin needs to enter the username and the password for authentication. Once authenticated, the admin can now create the question and store the answer for the same in the database. The admin can also add students, subjects and tests for those subjects. The admin should keep all the keywords present in the answer in capital letters. Thus admin should store the answer with a subject expert helping him to identify the keywords present in the answer. The question will be displayed to the user and the answer stored will be used …show more content…
User Login:
The user login enables the user to write the answer for the question displayed. The user is asked to enter his login id and test id. If all the credentials are satisfied then the student is redirected to the page where the question and a text box for the answer is displayed. Once the user has completed writing the answer, he/she can submit the answer for evaluation.
2. Information Extraction Module:
Information extraction module is a module where the process of extracting the keywords from the standard answer and the user submitted answer will take place. Along with the keywords, the synonyms of the keywords submitted by the user will also be extracted. The keywords are the words that provide the key concept or are of great significance in a document. The keywords that get repeated very often in a document are given less importance. But the keywords which occur rarely in a document will have great importance. The synonyms of the keywords will be extracted from the dictionary stored in the database. [6][7].
