Ontology of time metrology vocabulary

The advent of the digital era has put forward an urgent need for the digitization of metrology, and the digitization of metrology vocabularies is one of the fundamental and critical steps to achieve the digital transformation of metrology. Metrology vocabulary ontology can facilitate the exchange and sharing of data, which is an important way to achieve the digitization of metrology vocabulary. Time metrology vocabulary is a special and important part of the whole metrology vocabulary, and constructing its ontology can reduce the problems caused by semantic confusion, help the smooth progress of metrological work, and promote the digital transformation of metrology. Currently, the existing ontology for metrology vocabulary is primarily the MetrOnto ontology, but it lacks a systematic description of the vocabulary of time metrology. Based on Web Ontology Language (OWL), a bilingual time metrology vocabulary ontology OTMV is designed and constructed using a seven-step ontology development methodology.OTMV provides a standardized, interoperable, and unified architecture, which realizes the bilingual digital representation of time metrology vocabulary in the national standards of China, metrological technical specifications JJF1180-2007 "Glossary and Definition of Time and Frequency Metrology", JJG 2007-2015 "Time and Frequency Measuring Instruments", and relevant materials published by the China National Institute of Metrology.数字时代的到来对计量数字化提出了迫切需求，而计量词汇数字化是实现计量数字化转型的基础性关键步骤之一。计量词汇本体（Ontology）可促进数据的交换与共享，是实现计量词汇数字化的重要路径。时间计量词汇是整个计量词汇体系中兼具特殊性与重要性的组成部分，构建其本体可减少语义混淆引发的各类问题，助力计量工作顺利推进，并推动计量数字化转型。当前，现有的计量词汇本体主要为MetrOnto本体，但该本体未对时间计量词汇开展系统性描述。本研究基于网络本体语言（Web Ontology Language, OWL），采用七步本体开发方法论，设计并构建了双语时间计量词汇本体OTMV。OTMV 构建了标准化、可互操作且统一的架构，实现了中国国家标准、计量技术规范JJF 1180-2007《时间和频率计量词汇与定义》、JJG 2007-2015《时间频率测量仪器》以及中国计量科学研究院发布的相关资料中时间计量词汇的双语数字化表征。
