Three word list experiments investigated how people organize data. Sets of 15 to 20 words had pre-defined organizations hierarchy, networks, lists, table, and random, based on semantic relations. Experiment 1 indicated that college students had these organizational structures available for use. Most subjects used organizations that most easily preserved the relations, but a few organized nearly all sets into lists which maintained the semantic relations. Experiment 3 showed how subjects have difficulty in preserving relations among data if required to organize into inappropriate structures. Results are evaluated for use in computer based information retrieval systems.
