Summary of Application and Prospect Analysis of Knowledge Graphs in Marine Field

doi:10.3778/j.issn.1002-8331.2106-0351

Abstract

Abstract: The knowledge graph is mainly used to extract essential information from complex data to generate a relational network. Its excellent recognition ability for complex relations and strong description ability for data make knowledge graph technology have high application value. This article provides theoretical support for applying knowledge graphs in the marine field and gives a general overview of the related technologies of knowledge graphs. It explains the excellent application of Citespace’s document analysis tools. It systematically sorts out semi-structured and unstructured data extraction techniques in the marine field and analyzes the principle and subsequent improvement of critical technologies such as named entity recognition, relation extraction, event extraction, knowledge fusion, and knowledge reasoning. The landing scene and prospects of applying knowledge graph technology in the marine field are summarized and prospected.

Key words: knowledge graph, named entity recognition, relation extraction, event extraction, knowledge fusion, Citespace
