Embodiment Construction

[0059] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.

[0060] Due to the need for the accuracy of the representation of elementary mathematical knowledge, such as in the proposition, it is necessary to introduce the known entity and the entity conclusion according to the proposition representation. The known entity and the entity conclusion divide the proposition into two parts, so as to meet the requirements Precisely express the necessary and sufficient relationship among them...

Abstract

The invention discloses an elementary mathematics knowledge graph construction method based on Neo4j and big data, and belongs to the technical field of elementary mathematics knowledge graph construction. The method comprises the following steps: respectively defining entities, relationships and attributes according to a Neo4j graph database, and constructing an initial knowledge graph from top to bottom; and perfecting the initial knowledge graph according to a big data and deep learning bottom-to-top construction method to obtain a complete elementary mathematical knowledge graph. The elementary mathematics natural language text is converted into the elementary mathematics domain knowledge graph, and the relation between entities in elementary mathematics questions is clearly and accurately expressed.

Description

technical field [0001] The invention belongs to the technical field of elementary mathematics knowledge map construction, and in particular relates to a method for constructing elementary mathematics knowledge map based on Neo4j and big data. Background technique [0002] Since Google proposed the concept of knowledge graph in 2012, many research institutions and technology companies at home and abroad have begun to build knowledge graphs, which involve many fields, such as search, e-commerce, financial risk control systems, medical care, education, etc. At the same time, many domestic Internet companies and universities are also building knowledge maps. For example, Baidu has been committed to building "Baidu Zhixin" with knowledge graph as the core to enhance the company's search engine; Sogou has also built a knowledge graph "Knowledge Cube" to enhance its search engine; in April 2018, Alibaba He took the lead in the discussion on knowledge engine research. The knowledge...
