摘　　要：为了在产品创新设计过程为设计者提供跨领域的专利知识,提出一种以功能基为分类标准的中文专利文本分类方法。针对功能基类别多、专利文本训练集少的特点,从简化类别数量和增加数据集2个角度出发,采用多重二分类监督分类算法和基于EM算法的半监督分类算法,以朴素贝叶斯（NB）完全有监督算法为对照,采用正交实验,考察特征选择与数据集选择对分类准确度的影响,实现一级功能基分类准确率达到80%,基本符合应用要求。为基于功能基辅助产品创新设计专利知识库的构建,提供了相关的技术支持。Objective To explore the means of haemostasis in gallbladder preserving cholecystolithotomy. Methods The clinical data of 31 cases were retrospectively analyzed, summarizes the successful experiences. Results There appeared 31 cases the gallbladder internal bleeding in 512 cases gallbladder preserving cholecystolithotomy. In all the cases, 31 operations were stopped bleeding satisfactorily and performed successfully without conversion to conventional laparoscopic surgery, without perforation of gallbladder, pressure and lavage hemostasis had common effect, the control coagulation hemostasis had satisfaction rate 96.6%. Except one patient used gallbladder whole layers suture method. Conclusion The control coagulation hemostasis with the high-frequency electric knife is the optimal way, pressure and lavage hemostasis is basal, and gallbladder whole layers suture method is supplement.
