automated short-answer grading (ASAG) is a crucial element of any intelligent tutoring platform. Machine learning (ML) has shown great promise for ASAG. However, this task remains challenging even for Deep learning (DL) approaches and Large Language Models (LLMs), requiring semantic inference and textual entailment recognition. the SemEval-2013 Task 7, the Joint Student Response Analysis and 8th Recognizing Textual Entailment Challenge, is a benchmark widely used for research on ASAG. the SciEntsBank data included in this collection contains nearly 11,000 answers to 197 assessment questions in 15 different science domains. Despite the popularity, only a few researchers have explored the potential of DL or LLMs for this task. In this project, we explore the effectiveness of the RoBERTa Large model, an LLM trained on an extensive text corpus for language comprehension. By fine-tuning the model on the Multi-Genre Natural Language Inference (MNLI) corpus for semantic inference and subsequently on the SciEntsBank dataset, with a focus on the 3-way labels of correct, incorrect, and contradictory, we achieved a weighted F1-score of 0.77, 0.72, and 0.72 on unseen answers, questions, and domains, respectively. Notably, our model significantly benefits from fine-tuning on the MNLI corpus, particularly in enhancing its performance on the contradictory class (which constitutes only 10% of the dataset) through transfer learning leading to significant improvements on the more challenging test sets: unseen questions and unseen domains.

this document introduces the basic concepts of Artificial Intelligence (AI) and Machine learning (ML), and some typical applications are mentioned;It also describes some of the most used AI platforms to develop projects using ML algorithms. Specifically, the implementation of Machine learning solutions is addressed using the MediaPipe framework developed by Google. MediaPipe uses pre-trained models in TensorFlow, OpenCV to manipulate video, and FFmpeg to handle audio data;in addition, it is available for Android, iOS, C++, Python, and JavaScript.
