Abstract Currently, the research of patent technology effect matrix and technology application map is primarily depend on the judgement of experts in classification of technology, effect and application terms, which requires many labors and the result seems to be not comprehensive. Therefore,the paper proposes a relatively objective solution based on text mining. This solution mainly focuses on the extraction of patent information about technology, effect and application terms, and then the experts make decisions based on the results of extraction to define the relatively comprehensive and accurate terms. With these terms, the maps by calculating the numbers of terms and the times of occurrences among them can be built. Experimental results show that the finally statistics are more comprehensive relative to experts’ ways.
