Abstract
A patent evaluation method and system thereof are provided. The method includes collecting patent documents, and further includes the following steps: generating technical points and patent-affiliated technical points; generating technical clusters and patent-affiliated cluster; performing a patent evaluation in each of the technical clusters. The patent evaluation method and system proposed in the present invention aggregates the patents in a technical cluster mode through natural language processing and complex network algorithms, gives patents scientific and technological attributes, and places the patents in a global same industry for evaluation.
