Knowledge Acquisition and Knowledge Innovation Based on Visualization Technology in Digital Library

Considering the lack of visualization technology applications and e-learning in the current digital library construction, a visualization knowledge acquisition and knowledge innovation prototype system is designed in the paper. The visualization display and visualization mapping are used in the prototype system, and it realizes a complete knowledge chain from information extraction, knowledge acquisition, knowledge construction and knowledge innovation to userspsila knowledge storage. It may provide ideas of applying visualization technology in digital library.
