As the world's largest source of the technical information, patents have received increasing attention by the enterprise. A patent mining and analysis process is presented based on Chinese word segmentation. First, the patent information is searched, extracted, and cleaned. Then some keywords have been extracted from patent title based on Chinese word segmentation, and the patent title, abstracts, and other patent information are refined. Last, patent technology roadmaps, the association between different technologies, similar patent cluster, etc. have been mined based on the previous research. This process and method has been applied to the patent of air-conditioning industry. It helps the enterprise in the patent mapping, technical development, and implementation of patent strategy.
