Abstract :
On-line knowledge discovery is an important area of knowledge engineering. This paper develops a visualized concept network explorer and a semantic analyzer to locate, capture, and refine queries based on concept algebra. A graphical interface is built using concept and semantic models to refine users´ query structures. This tool kit can generate a structured XML query package that accurately express users´ information needs for on-line searching and knowledge acquisition.
