Embodiment Construction

[0055] The supply chain operation knowledge graph construction process is shown in Figure 2, forming a structured semantic knowledge base.

[0057] 1) Data acquisition. Through the operation process of various financial, management, logistics, production, design and development and other aspects of data

[0058] 2) Knowledge extraction. The purpose of this stage is to automatically extract information from heterogeneous data sources to obtain structured knowledge sheets

[0060] 4) Knowledge fusion. Through coreference resolution, entity disambiguation, entity linking and other technologies to achieve coal plant design knowledge base,

[0061] 5) Knowledge processing. The data after knowledge fusion cannot be stored directly, it needs to pass a certain level of quality

[0062] 6) Knowledge storage. The data after knowledge processing is stored in the Neo4j graph database, which is convenient for graph data

[0065] 3.1) Data source

[0067] 1) Structured data. It mainly refe...

Abstract

The invention relates to a supply chain operation knowledge graph construction method and system. The method comprises the following steps: acquiring data in a supply chain operation process; performing knowledge extraction on the acquired data in the supply chain operation process; constructing an ontology library according to the extracted knowledge, and performing knowledge fusion on the supply chain multi-source data based on the ontology library; performing knowledge processing on the data after knowledge fusion so as to ensure the storage quality of knowledge; storing the data after knowledge processing by adopting a graph database to form a supply chain operation knowledge graph; and realizing knowledge service application on the basis of the supply chain operation knowledge graph, wherein the knowledge service application comprises a supply chain operation field-oriented knowledge semantic retrieval service and a user portrait-based knowledge accurate pushing service. According to the method, the knowledge graph fusing multiple data sources is constructed, rapid query of data in different fields can be achieved, a semantic retrieval function can be supported, the requirement of a user for cross-stage knowledge association retrieval is met, the cooperative work efficiency is improved, and the auxiliary decision-making level is improved.

Description

A method and system for constructing a knowledge graph of supply chain operations technical field [0001] The present invention belongs to the field of information technology, and in particular relates to a method and system for constructing a supply chain operation knowledge graph. Background technique In the context of the era of big data, with the emergence of massive data and multi-data source fusion and cross-application, traditional The data management mode and query method are subject to certain restrictions. In recent years, knowledge graph (Knowledge Graph) as a It is a new knowledge representation method and data management model, with emphasis on natural language processing, question answering, information retrieval and other fields. desired application. Knowledge graphs are structured semantic knowledge bases used to describe concepts in the physical world and their Interrelationship; its basic unit is the "entity-relation-entity" triplet, as well as the...
