Embodiment Construction

[0028] In recent years, Knowledge Graph, as a new knowledge representation method and data management model, has important applications in many fields such as display, question answering, and retrieval. The knowledge graph is a structured semantic knowledge base, which is used to describe related concepts and the relationship between them in the form of symbols. Its basic unit is the "entity-relationship-entity" triplet, and the entity and its related attribute values Yes, entities are connected to each other through relationships to form a networked knowledge structure. Various functions such as ideological and political knowledge system display, ideological and political knowledge question and answer, and ideological and political knowledge reasoning can be completed by constructing an ideological and political knowledge graph. Due to the wide range of sources of knowledge in the ideological and political field, there are various carriers such as books, news, important speec...

Abstract

The invention discloses a knowledge graph construction system and method, being characterized in that firstly, different ontology libraries are constructed for different data sources and data types; then all the ontology libraries are mapped into a global ontology library; then entity alignment and entity linking are conducted on the global ontology library, serving as a knowledge base, of all thesources, and the constructed multi-data fusion ideological and political knowledge graph is perfected and expanded. The knowledge graph construction system and method construct an ideological and political knowledge graph to complete multiple functions such as ideological and political knowledge system display, ideological and political knowledge questioning and answering and ideological and political knowledge reasoning, and can effectively overcome the defect that in the prior art, a traditional data management and display mode cannot enable students to well learn ideological and politicalknowledge and understand an ideological and political knowledge system.

Description

technical field [0001] The present invention relates to the technical field of knowledge graphs, in particular to a knowledge graph construction system and method. Background technique [0002] Knowledge Graph, known as knowledge domain visualization or knowledge domain mapping map in the library and information industry, is a series of different graphics showing the knowledge development process and structural relationship, using visualization technology to describe knowledge resources and their carriers, mining , analyze, construct, map and display knowledge and their interconnections. The knowledge map is a combination of theories and methods of applied mathematics, graphics, information visualization technology, information science and other disciplines with metrology citation analysis, co-occurrence analysis and other methods, and uses the visual map to vividly display the core structure and development of the subject. History, frontier fields, and the overall knowledg...
