In recent years, research into automatic grading has accelerated significantly. Right now, there has never been a greater need for an effective ASAG system. The start of the pandemic and the switch to online learning have given the research even more momentum. Several methods have been suggested by authors from around the world to resolve the ASAG task. The purpose of this work is to demonstrate how models based on Transfer Learning and optimization methods using swarm intelligence can be utilized to grade short answers. In the proposed research, we introduce a short answer grading system using BERT, BiLSTM, CNN with PSO optimization. To increase the performance of the scoring systems, we optimize the input features using PSO and then given to the hybrid deep learning based model consisting of the BERT, BiLSTM and CNN to classify the answers as correct, partially correct and incorrect. The model is tested using the base line data set i.e., Mohler data set as well as a newly created Computer Science data set in Indian context (CSDSIC). Various experiments are conducted to test the performance of the model. The performance metrics used for evaluating the model are accuracy and root mean squared error. Model shows an accuracy of 92%.
