Semantic-based digital standard meta-model and application method thereof

Abstract

The invention relates to a digital standard meta-model based on semanteme and an application method thereof, the meta-model comprises three parts of data contents, namely DSS general ontology, technical description data and structure and data constraint, which are established based on a unified semantic framework, and semantic elements in the unified semantic framework comprise DSS composition classes, DSS object relationships, DSS object attributes and DSS object instances; the DSS composition class is divided into a primary class and a secondary class and is used for concluding concepts. According to the method, content expression of standard elements is achieved based on unified semantics, DSS is automatically read, understood and processed through a computer, automatic comparison between DSS models or DSS examples is achieved, conformity of products or processes and batch products is automatically judged, and reasoning decision and automatic control are conducted based on the DSS; through registration, reference and inheritance mechanisms, sharing and reusing of standard elements are achieved, and the efficiency of digital design and standard system revision and the standard implementation benefits are improved.

Description

technical field [0001] The invention relates to the application of semantic technology in the field of standardization, and also relates to quality management and requirement engineering technology, specifically, a digital standard meta-model based on semantics and an application method thereof. Background technique [0002] Standards are an important basis for product design, production and test acceptance. Traditional forms of standards usually refer to standard documents written in natural language (using paper as a common carrier, or scanned and transferred to a computer to form standard documents in digital form), with the main purpose of being read and understood by people. Standard documents are mainly composed of elements such as preamble, scope, and term definitions. The text structure of standard documents is mostly chapters, sections, articles, items, etc. [0003] With the emergence and development of computer technology, especially computer graphics, in more an...

Problems solved by technology

[0008] 1. There is a lack of a complete and unified semantic relationship between standard elements in the digital form standard, and there is no clear and unified verification rule and / or judgment rule, making it difficult to automatically obtain compliance results;

[0009] 2. The requirements in the digital form standards have defects of incomplete structural information. Such defects often manifest in that the relevant prerequisites or product levels are not structured and related in the requirements, so it is impossible to guarantee that the requirements under the same prerequisites or product levels Obtain compliance results automatically;

[0010] For example: the requirements for the melting point of products in the digital form standard, the relevant premise "atmospheric pressure conditions of the test" is not structured and related, which may lead to the misuse of this requirement or invalid compliance results based on this requirement of;

[0011] Another example: in digital standards, for products with grading and grading requirements, the corresponding requirements are not structured and related according to "product grade", which may lead to the risk of mistakenly comparing and judging products of different grades, and it is difficult to accurately Support automatic grading and grading of products;

[0012] 3. When there is a multi-level reference relationship between digital form standards, as the complexity of the reference relationship increases, the requirements in the digital form standards may be unclear, and the inheritance and reuse of requirements cannot be accurately realized
