Research on clustered patent mapping visualization and interaction

Patent mapping, which is a series of mapping process with patent information, especially those unstructured information, such as patent claims, details and patent illustrations, is an important tool of patent analysis. Clustering is a popular method to mining the knowledge hidden in patents and provides abundant information to the visualization and interaction of patent mapping. A method of projecting the patents clustering tree along three directions to create tree-shaped patent map, scatter plot patent map and parallel coordinates patent map was proposed. A visualization and interaction structure was also set up based on Flex technology.
