摘　　要：图形用户界面(Graphical User Interface,GUI)领域的检索实践中,较多案例仍然采取使用单一分类号结合关键词或者仅仅使用关键词进行检索,需要不断扩展关键词,针对此情况,文章对比了GUI领域中IPC和CPC的分类特点,指出CPC分类号的分类优势,结合GUI领域技术方案往往涉及多技术分支的特点以及该领域分类号分布特点,提出一种快速确定该领域技术方案分类号的方式,并结合具体案例,使用上述方式进行检索实践,可以快速准确地找到合适的对比文件。To date,most of cases are searched by a single classification number combined with key words or even only by key words in the field of Graphical User Interface(GUI),which are generally limited by the number of key words.This paper compares the characteristics of IPC classification system with characteristics of CPC classification system to analyze the advantages of CPC classification in the field of GUI.The technical solutions usually involve multi-branch technology and possess special distribution features of classification system in the field of GUI,thus this paper presents a method for quickly determining the classification of technical solutions.In addition,this paper searchs specifi c cases through the method which can obtain the appropriate reference document rapidly and accurately.
