The Research On Visualization Methods In Data Mining

Now, We just live in the age of network, communication computer and internet are changing the people's life and the whole society. Lots of information brings some problems as thought they bring much convenience to us. People begin to think that how to find the useful knowledge in the information sea, and keep from submerging in it? Facing these problems, Data Mining and Knowledge Discovery technologies have appeared, it is one of the newest technologies that combine human' s explore ability and computer* s great ability. Information visualization is a new study that involves in computer graph, image processing, CASE, computer sight, GUI methods, system design, signals, and human-computer interaction.Visualization and data mining are two fields that make use of each other. Visualization can greatly motivate human's activities when using it as a technology of data mining. People are willing to explore and may get what he wants during to the visualization. It is notwithstanding but very important that using visualization as the bridge between computer and users to show them those information directly. The traditional mining procedure is invisible and indirect, user cannot tamper in it, so it looks like a "black box* and users are doubted about the conclusion. Visualizational data mining can greatly improve the efficiency of data mining and get more valuable results. Its purpose is to make users explore information and mine interactively with the computer. Images are mush easier for people to identify than digital tables.In this article, firstly the author introduces some basic conceptions, impacts, applying and problems about the visualization and data mining technologies. Based on these researching, then gives a special emphasis on the combination of them, and its great meaning, applying and tendency. And then fix eyes on the framework of visualizational data mining system.
