Stephanie W. Haas is a Professor in the School of Information and Library Science at the University of North Carolina at Chapel Hill, and Program Coordinator for the SILS Master's of Science in Information Science program. Her research interests focus on the representation of information, and how representations enhance or impede work processes. More specifically, she is interested in natural language processing: what computers do with the language people use. Current and recent projects study these issues in collaboration with researchers from UNC's Schools of Medicine, Nursing, and Public Health, examining information representation in patient records, and its use for improving patient care. An award-winning teacher, she teach courses in Applications of Natural Language Processing, Systems Analysis, and Database Design (including an online version).
Courses Regularly Taught:
INLS 512, Applications of Natural Language Processing
INLS 523, Database 1 (online and face-to-face)
INLS 582, Systems Analysis
