has different names, but also contains GIS information such as longitude and latitude, and can be

functions based on a map. In addition, the more accurate browsing is fulfilled via another two
ways. One is called “timeline map” browsing, and the other is called “map circle” browsing. For
“timeline map” browsing, users can drag the timeline and discover how the created genealogy
during a period of time is distributed on the map. For “map circle” browsing, by drawing a scope
on the map, all the genealogies of the place within this region will be presented, and details are
shown in Figure 5.

2.4.3 Platform optimization
The platform is open to users for mutual communication and interaction. It supports researchers,
students, civil societies and other users from related domains to leave messages and feedbacks,
modify data, and contribute knowledge. These activities will add the value and realize the
proliferation of data during the use.
(1) Feedback and communication
For readers who hold the Shanghai Library card or the registered user through online registration
system of the Shanghai Library can directly log onto the platform. Users can raise questions
on certain genealogies by writing feedbacks and comments. Questions include inquiries on the
bibliographic information of this genealogy, such as title or creator, or opinions and comments on
