Small world property-based engineering information organization method

Abstract

The invention discloses a small world property-based engineering information organization method, which comprises the following steps of: first performing characteristic data description on an engineering information file to form a characteristic vector; then establishing a network topology structure with small world properties; and finally storing, retrieving and maintaining the newly added engineering information file based on the network topology structure. By the method, effective support is provided for the long-term storage, information extension and post maintenance of information, fine grit comparison is performed in the calculation of similarity among different engineering information nodes, and the information query precision and accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of computer network intelligent information retrieval, in particular to an engineering information organization method based on small-world characteristics. Background technique [0002] With the rapid development of computer and network technology, the growth of information volume far exceeds the growth of people's ability to obtain information. Primitive and disordered information not only does not produce value, but also exacerbates the contradiction between information growth and utilization, resulting in a social dilemma of information overload and lack of knowledge. Therefore, the orderly storage and utilization of massive information resources has attracted more and more attention from all over the world. The storage and utilization of engineering information, especially the preservation and utilization of engineering information in the field of manufacturing, is still a challenging problem. [0003...

Problems solved by technology

At present, the preservation and utilization of engineering information are mainly based on the following methods: (1) Based on electronic documents, microfilm, punched cards, etc. in the form of traditional drawings, the information resources preserved by this method are prone to aging or damage, and are not easy to call on the network (2) Based on the STEP ISO 10303 standard, the 3D CAD model incorporating design and manufacturing information, because the life of the CAD system that generates this information is much shorter than the life of most products Many, there will be compatibility issues between data and systems in future use

In addition, research on the generation method of engineering information and the long-term preservation of digital engineering information and ensure the reliability of data can meet the various needs of different users in different periods and in the future. However, to ensure its long-term safe preservation and data reliability, it is necessary to These information resources must be regularly inspected, transferred, and converted. These regular processing processes not only have the compatibility issues mentioned above, but also encounter the time and efficiency issues of information processing.
