Abstract: In order to allow knowledge workers to manage their personal information flexibly, sequentially and intelligently, a model for managing personal information model is proposed. First, the features of the knowledge workers for managing personal information are analyzed. Next, the architecture of the model is provided and the structure of it is described. Some tag-based, personal-information recommendation methods are introduced later. Finally, the evaluation results of the overall system show that the model could meet the knowledge workers’ requirements for managing personal information.

Key words: computer application, personal information management model, tag, knowledge worker
