F-TERM分类号在C23领域中的检索应用

Retrieval Application of F-TERM Classification in the C23 Field

C23领域涉及表面镀覆以及金属蚀刻和防腐,日本专利申请在该领域中占据突显位置。日本特许厅开发的F-TERM分类号是一种专为计算机检索而设计的分类体系,该分类体系从多种不同的技术角度进行细分,从而构成一个技术主题的立体细分。本文通过F-TERM分类号与IPC、CPC分类号的比较,结合具体案例探讨了F-TERM分类号在C23领域的检索应用,说明了F-TERM分类号在该领域中的检索优势,以期为C23领域的高效率检索提供一定的借鉴与参考。

The C23 area covers surface plating as well as metal etching and anti-corrosion. Japanese patent applications occupy a prominent place in the field. The F-TERM classification developed by the Japanese Patent Office is a classification system designed for computer retrieval. F-TERM classification is subdivided from a variety of technical perspectives, thus constituting a three-dimensional subdivision of a technical topic. By comparing F-TERM with IPC and CPC, this paper discusses the retrieval application of F-TERM classification in C23 field, and explains the retrieval advantages of F-TERM in this field, in order to provide some reference for the efficient retrieval in C23 field.
