Abstract: This study utilizes the synoptic catalog from Chinese Genealogy Knowledge Service Platform and applies technologies such as ontology and associated data, GIS and visualization to extract and exploit knowledge of migration information contained in genealogical literature, and designs and develops an interactive visual presentation project with migration spatio-temporal data for narrative, and delivers the service in multiple terminals and scenes, thereby enhancing the utility of genealogical literatures and pioneering innovative knowledge service models for genealogy. This study mines, organizes and visualizes large-scale data to provide new ideas for the promotion and utilization of the unique resources of library collections. It also offers new methods for the presentation and dissemination of humanities knowledge, and broadens the scope of digital humunities services to encompass the general public.
