Natural Language Processing (NLP) and text mining technologies serve as foundational tools in enabling AI to support human intellectual activity and foster social innovation. In an age of overwhelming information, these methods help extract essential concepts and uncover semantic relationships, guiding users toward relevant knowledge and insights. While current AI systems lack true consciousness or self-awareness, emerging approaches attempt to simulate elements of intentionality and emotional recognition. NLP allows machines to interpret the nuances of human communication—such as sentiment, intent, and context—bringing us closer to AI that not only processes information but responds in a way that appears thoughtful or empathetic. These developments represent a step toward building AI that better understands and aligns with human values—fueling innovation aimed at creating more sustainable, inclusive societies.
We conduct research in but not limited to
Understanding media content, intent, and emotions through the analysis of human intellectual activities and conversations.
Prediction of human intellectual activities and communications, leading to social innovation.
Knowledge representation, intellectual activities, and language comprehension.
Innovation through interdisciplinary synergy and integrity.
