Abstract：In analyzing unstructured information of patents, there is a problem in identifying and defining the technology innovations and the effect of patent currently.This paper puts forward a method to differentiate technical and effect words in patent,based on the features of patents’ structure-grammar-clue word.The method can synthetically consider three feature factors: the structure, the grammar and clues word, then improve the recognition result of the technical and effect words in patents.
