description The invention discloses a recognition method of the knowledge field in text. The method comprises the steps that with a judgment of positions of related concept fields and a target concept field, if the number of the related concept fields is unique, a concept/relation pair is found; if the number of the related concept fields is not unique, a relative distance between the related concept fields and the target concept field in the same sentence or the adjacent sentences is calculated; if the relative distance is greater than or equal to the threshold value, the related concept fields which are closer to the target concept field are concept/relation pairs; if the relative distance is less than the threshold value, an analysis and judgment is needed according to a context, so that the matching relation between the knowledge fields in the text can be processed quickly, thereby improving the recognition efficiency of the knowledge fields in the text. The invention further discloses a recognition system of the kno
