This paper presents an automatic approach to creating taxonomies of technical
terms based on the Cooperative Patent Classification (CPC). The resulting
taxonomy contains about 170k nodes in 9 separate technological branches and is
freely available. We also show that a Text-to-Text Transfer Transformer (T5)
model can be fine-tuned to generate hypernyms and hyponyms with relatively high
precision, confirming the manually assessed quality of the resource. The T5
model opens the taxonomy to any new technological terms for which a hypernym
can be generated, thus making the resource updateable with new terms, an
essential feature for the constantly evolving field of technological
terminology.

本文提出了一种基于专利合作分类（CPC）的技术术语分类自动化方法，生成的分类包含 9 个独立技术分支中的约 170k 个节点，并且使用 Text-to-Text Transfer Transformer (T5) 模型 fine-tune 生成上下位词并得到相对较高的准确性，从而证明了此资源的质量。T5 模型可以打开新的技术术语的分类（根据上下位关系），因此这个资源可以更新，是技术术语领域不断发展的必要特性。
