Un Nuevo Enfoque para la Puntuación Automática de Problemas cuya Resolución se basa en Diagramas = A New Approach to Automatically Evaluate Problems that are Solved using Diagrams

Automatic correction of problems that are solved using diagrams through educational platforms is of great importance, especially in the field of engineering studies. In this paper, we present a new strategy to automatically assess diagrams. The proposed approach is described in detail as well as its application to assess entity/relationship diagrams used in the conceptual design of databases. The results indicate that the differences between manual and automatic assessment is less than 075 points over a total of ten which confirms the validity of the proposed approach. As a conclusion, the validity of the proposed method to assess entity/relationship diagrams reducing teacher correction time and unifying applied correction criteria is corroborated ​
