中文摘要：

为了获得专利文献中的产品功能与结构的相关知识，提出一种基于关联规则的知识获取方法．通过提取专利文献的权利要求书中特征零部件，分析标题或摘要中的目的功能和手段功能，建立手段功能-特征零部件和目的功能-手段功能的训练集，并采用作者提出的修剪分类算法提取它们之间的关联规则，获得特征零部件-手段功能-目的功能之间关系的知识，以辅助产品的持续创新．并以冲击钻为例验证了该方法的有效性．

英文摘要：

To acquire associational knowledge from descriptions of product function and structure in patents, a new method for knowledge acquisition based on association rules was proposed. Training sets were established by first extracting featured parts in claims, analyzing objective functions and artifice function in the abstract or title, in which featured parts-artifice function and artifice function-objective function were constituted. Then it extracts associational rules hidden between them by a new efficient pruning-classification association rule developed by the authors. Knowledge among featured parts, artifice function and objective function can then be discovered and used to support continuous product innovation. The method was demonstrated using hammer drill patents. The results obtained prove the validity of this method.
