摘要
相对于IPC分类体系,CPC分类体系的分类条目更加精细,塑料加工领域涉及工艺类型繁多,各工艺的设备结构部件繁杂,检索要素表达方式多。利用IPC分类和关键词检索,组合形式难以穷尽,并且噪音大,因此,检索效率较低。文章结合塑料加工领域的特点,从实际案例出发,分析了塑料加工领域CPC分类号的应用方式和检索技巧,以提高检索效率。
Compared with the IPC classification,the CPC classification system are more refined.The plastic processing field involves many types of processes,and the equipment is complicated.There are many ways to express search elements.Using IPC classification and keywords to search,the combination of forms is difficult to exhaust,and the noise is large,so the search efficiency is low.Based on the characteristics of the plastic processing field,this paper analyzes the application methods and retrieval techniques of CPC classification in the plastic processing field from actual cases to improve retrieval efficiency.
