Hierarchical knowledge modeling structure taking relation as core and knowledge graph construction method

Abstract

The invention discloses a hierarchical knowledge modeling structure taking a relation as a core and a knowledge graph construction method, and relates to the technical field of knowledge modeling. The basic idea of the method is that the relationship is used as a first class of entities, the knowledge is expressed by taking the relationship as a core, and different entity elements are associated through the relationship. Through relation modeling knowledge, a knowledge graph is organized and managed so as to support unified identification and effective modeling of complex relations such as binary relations, multivariate relations and high-order relations. According to the method, knowledge can be effectively concluded and classified by adopting the hierarchical knowledge graph, so that knowledge organization is facilitated; the high-level knowledge graph can be reused, so that the construction cost of the knowledge graph is reduced, and the low-level knowledge can correspond to the uniqueness of different fields, so that the modeling of field knowledge rich in characteristics is facilitated.

Description

technical field [0001] The present invention relates to the technical field of knowledge modeling, and more specifically relates to a hierarchical knowledge modeling structure and a knowledge map construction method with relationships as the core. Background technique [0002] With the continuous development of human society, the scale and complexity of knowledge continue to grow, and the multiplication cycle of knowledge continues to shorten. The emergence of the Internet provides a more convenient medium for the acquisition and dissemination of knowledge, which further accelerates the growth rate of knowledge scale. Most of the knowledge accumulated by humans so far is described in the form of natural language. The unstructured form of natural language is not conducive to the efficient storage, use and dissemination of knowledge in terms of efficiency. Therefore, how to represent and organize knowledge in a structured form is a problem worthy of attention. [0003] Knowl...

AI Technical Summary

Problems solved by technology

Knowledge graphs centered on entities have the following deficiencies: (1) Most knowledge graphs only focus on the representation of instance-level knowledge, ignoring the modeling of upper-level conceptual knowledge; (2) There is generally a lack of explicit multi-relationships Modeling support, not to mention high-order relationships; (3) More attention is paid to the representation of static knowledge, lacking more descriptions of predicates (that is, relationships), for example, adding time information to predicates in order to effectively build relationships mold
