Embodiment Construction

[0026] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Based on ontology (Ontology) technology, the knowledge system of packaging engineering is described and stored in the database to allow dynamic adjustment and expansion of the knowledge system with the development of technology.

[0028] 1. Packaging engineering knowledge description language

[0029]According to the characteristics of the packaging engineering knowledge system, ontology technology is used to describe the packaging engineering knowledge system; it is necessary to design an ontology description suitable for packaging engineering knowledge description. The description language is based on OWL2.0 and can be opened by mainstream OWL2.0 compatible editors . The ontology description language of packaging enginee...

Abstract

The invention provides a knowledge graph-based packaging industry data search method and device. A packaging industry vertical field search engine can realize optimal retrieval efficiency and effect of the packaging industry field; a natural language query can be deeply understood; a user query intention is analyzed at a semantic level; massive structured knowledge bases can be utilized; an accurate answer is provided for a user query; and in addition, a synonym lexicon can be freely and flexibly expanded.

Description

technical field [0001] The invention relates to a packaging industry data search method and equipment based on a knowledge map. Background technique [0002] Packaging industry data is scattered in multiple systems, and data from different sources have different structures. It is difficult to aggregate this information with existing technologies, and there is a need for data fusion in the packaging industry. At the same time, most of the data on the Internet is unstructured data, which cannot be understood by computers. At the same time, when there are new business cognitions, it is difficult to change the mode of traditional relational database construction, and it is very difficult to modify the data structure and business logic, which will bring bad situations such as poor scalability and high maintenance costs. [0003] At present, the general search engine has been developed relatively mature, and its functions can already meet the basic search needs of users. However,...
