Abstract
A model for temporal knowledge visualization is presented to enhance reuse of temporal knowledge. The free-form, text-based temporal knowledge can be converted into visualized illustrations via the proposed visualization approach. The model includes three main modules namely full text tagging (FTT), event sequence analysis (ESA) and temporal knowledge visualization (TKV). The model can improve the efficiency and effectiveness for the knowledge receivers to acquire the temporal knowledge in the text-based documents and can be applied in enterprises for employee training and other activities.
