The present invention relates to a system receiving new traditional cultural content data and automatically learning and classifying the received data to automatically display a 3D digital chronology. The system performs: an operation of collecting structured and unstructured data through each traditional culture site; an operation of loading the collected content to be mapped to a cultural content data warehouse (CCDW) of a data storage unit; an operation of extracting time data among characteristics of the traditional cultural content and generating a basic digital chronology based on the extracted time data; an operation of performing mapping between the digital chronology and the content based on the time data and content interconnection network analysis; and an operation of visualizing and outputting content mapped with the basic digital chronology. The digital chronology visualized in 3D is configured to dispose a timeline indicating era and time in a y-axis direction, dispose a plurality of classification categories in a x-axis direction, and allow a plurality of sets of content each corresponding to the plurality of classification categories to be arranged in the y-axis direction to be mapped on the timeline such that it is possible to automatically display the digital chronology display system to provide an information user with a systematic classification and search function and a traditional cultural convergence service.
