Proposed framework for automatic grading system of ER diagram

In this paper we present a preliminary research with proposed framework for automatic grading system of Entity Relationship (ER) Diagram. The proposed framework use ER Diagram in XML file format (XMI file) as an input to the system. There are two proposed approaches. First approach is using Tree Edit Distance algorithm to assess ER Diagram similarity. The output is similarity score and feedback for inputted ER Diagram. Second approach is using machine learning algorithm to build classifier that grade ER Diagram automatically. These two approaches will be implemented and evaluated in the next phase of research.
