Natural Language Processing systems are computer algorithms that analyze language.  Our lab is at the forefront of connecting human psychology to natural language processing or artificial intelligence (AI).  We are especially (but not exclusively) interested in natural language processing of the complexity of language.

To that end, we have developed a state-of-the-art natural language processing system that scores the integrative complexity, dialectical complexity, and elaborative complexity of language.  This system was originally validated in two papers (Conway et al., 2014, Political Psychology; Houck et al, Political Psychology).  It has since been applied to gain insights about human behavior in mulitple arenas, including those relevant to business/industry, national security/terrorism, decision-making, health, religion, political ideology, personality, leadership, business, education, and popular culture.  A sampling of our own work related to natural language processing of complex language is below:
