Svitlana Volkova is a recognized leader in the field of computational social science and computational linguistics. Her scientific contributions and publication profile cover a range of topics on applied machine learning, deep learning, natural language processing, and social media analytics. Her research focuses on understanding, predicting, and explaining human behavior, interactions, and real-world events from open-source social data. Approaches developed by Dr. Volkova advance effective decision making and reasoning about extreme volumes of dynamic, multilingual, multimodal, and diverse real-world unstructured data.
