Embodiment 1

[0033] A knowledge integration method for product design process based on ontology, comprising the following steps:

[0034] (1) Lock the source of knowledge in the design process and read data: knowledge is a synonym for useful information and a display expression of data. The complexity of the product design process requires users of design knowledge (or knowledge management personnel) to be able to lock knowledge sources and read corresponding data according to the required knowledge;

[0035] (2) Through the type identification system, the knowledge sources are divided into three types: structured, semi-structured and unstructured knowledge sources: the complexity of the product design process makes the knowledge sources show significant heterogeneity. The diversity of knowledge expression forms is caused, such as design process knowledge exists in various forms such as relational database, XML file, HTML, .OWL file, sound, image, etc. This difference can seriously hinder...

Embodiment 2

[0048] A knowledge integration method for product design process based on ontology, comprising the following steps:

[0049] (1) Lock the knowledge source of the design process and read the data:

[0050] Knowledge is a synonym for useful information and a display expression of data. Due to the complexity of the product design process, knowledge exists in various forms, such as relational database storage, in the form of HTML, XML, and .OWL. At the same time, unstructured knowledge such as sound and images also exists in the product design process. Lock knowledge sources, read data, conduct a complete analysis of all knowledge sources, determine the storage form and meaning of knowledge sources, etc.

[0051] (2) Knowledge source type identification

[0052] Through the type recognition system, knowledge sources are divided into three types: structured, semi-structured and unstructured knowledge sources. For example, the information extracted from the HTML file is shown in ...

Embodiment 3

[0074] A knowledge integration method based on an ontology-oriented product design process (knowledge is a synonym for useful information and a display expression of data), the specific requirements of the product design process-oriented knowledge processing method are sequentially processed according to the following steps: knowledge source Read in, identify and classify knowledge sources, generate local ontologies of corresponding categories from original knowledge sources according to mapping rules, integrate local ontologies to obtain global ontology, and generate a shared knowledge base corresponding to global ontology; among them:

[0075] In the process of knowledge source identification and classification, it is required to identify the format of the original knowledge source, and on this basis, classify it into one of the following three categories: structured knowledge source, semi-structured knowledge source, unstructured knowledge source knowledge source; the presen...

Abstract

The invention relates to a knowledge integration method for a body-based product-oriented design process, which comprises the following steps in sequence: reading a knowledge source, identifying and classifying the knowledge source, generating a local bodies of a corresponding category by an original knowledge source according to mapping rules, integrating the local bodies to form a whole body, and generating a shared knowledge base corresponding to the whole body. Compared with the prior art, the invention fully considers the diversity of knowledge representation forms in the product design process, overcomes the simplicity of conventional integrated knowledge sources, and demonstrates excellent universality and completeness. Simultaneously, the invention provides an integrated rapid response mechanism for effective integration of knowledge sources with various storage forms and further demonstrates the feasibility of the mechanism.

Description

Technical field: [0001] The invention relates to a data processing method and method in the product design process, and in particular provides a knowledge integration method based on an ontology-oriented product design process. Background technique: [0002] In the existing technology, with the advancement of science and technology and the rapid development of productivity, the function and quality requirements of products are continuously improved, the update speed is continuously accelerated, and the complexity of product design is also increasing. [0003] The data involved in the product design process presents different storage forms, such as: structured storage, semi-structured storage, and unstructured storage such as sound and images. Different forms of expression make data sharing and integration an insurmountable obstacle. The heterogeneity of storage forms, that is, the different forms of expression, makes the interoperability between data complex and difficult, ...
