Prof. Dr. Ir. Anak Agung Putri Ratna, M.Eng.
Professor at the Department of Electrical Engineering, Faculty of Engineering, Universitas Indonesia
Her primary research focuses on Natural Language Processing (NLP) and educational technology. Her publication record demonstrates profound expertise in Automatic Short/Essay Answer Grading (ASAG/AES) and the development of AI-based e-learning systems. Her competencies include modeling with BERT/SBERT, Siamese-LSTM, and classical approaches such as Latent Semantic Analysis (LSA) for automated short answer and essay assessment. Her research has produced practical solutions in the field of education, including automated essay grading systems for Indonesian and Japanese languages, the integration of web-based learning platforms, and the exploration of semantic representation methods to improve grading accuracy. These works contribute directly to the quality of online learning evaluation by accelerating the assessment process while maintaining consistency and objectivity. Her expertise in NLP and educational technology drives research in text processing and AI implementation for education, serving as a vital pillar for the research direction of the SYNAPSE-AI group.
