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,...
