“…A KG primarily depicts the relationships among realworld entities, arranged in a graph structure [29]. Depending on the area covered, KGs can be classifed into two categories: domain KGs (e.g., geoscience knowledge graph [30] and the BMKG in this study) and general KGs (e.g., Freebase [31]). Domain KGs contain domain-specifc data with diferent attributes and data patterns.…”

“…Tere are usually two approaches to building KGs: bottom-up and top-down [30]. Te bottom-up approach starts with the construction of a data layer and subsequent defnition of a schema layer, and its reverse process is the top-down approach [30]. Te former is suitable for building a general knowledge graph, and the latter is extensively used in the construction of domain knowledge graphs [39].…”

To effectively manage the heterogeneous and discrete knowledge of the bridge maintenance domain, this study adopts knowledge graph technology to build a knowledge base of bridge maintenance, called the bridge maintenance knowledge graph (BMKG). The BMKG uses an ontology as the knowledge organization and representation framework and a graph database as the knowledge storage tool. To facilitate the construction of the BMKG, a hybrid method combining a top-down approach and a bottom-up approach is proposed. Firstly, a bridge maintenance domain ontology (BMDO) is coded with Protégé and represented in Web Ontology Language. Secondly, rule reasoning and ontology reasoning are implemented on the BMDO in Protégé in order to automatically complete missing relations or attribute values. Thirdly, ontology reasoning is adopted to perform consistency check on the BMDO. Lastly, the BMDO model is stored in the Neo4j graph database through data format conversion, thus completing the construction of the BMKG. The BMKG is applied in a typical scenario of bridge maintenance to demonstrate its application value. Results show that the proposed hybrid method can create a knowledge graph that can realize the transformation from discrete data into interconnected knowledge. Knowledge graph offers a novel idea to create a knowledge base in the bridge maintenance domain.

“…As a technical system, knowledge map is representative of progress in knowledge engineering in the age of big data [ 23 ]. In recent years, knowledge mapping technology has been widely used in various fields [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ]. It can show the development and structural relationship of scientific knowledge through graphics and can create the mathematical expression that reveals scientific knowledge and laws to graphical expression.…”

Cancer is one of the most difficult medical problems in today’s world. There are many factors that induce cancer in humans, and obesity has become an important factor in inducing cancer. This study systematically and quantitatively describes the development trend, current situation and research hotspot of the relationship between cancer and obesity by using document statistics and knowledge graph visualization technology. Through the visualization technology analysis of knowledge graph in this study, the research hotspot and knowledge base source of the relationship between cancer and obesity in the last 20 years have been ascertained. Obesity-related factors, such as immunity, insulin, adiponectin, adipocytokines, nonalcoholic fatty liver and inflammatory reaction, may affect the occurrence of obesity and increase the risk of cancer. Obesity-related cancers include respiratory cancer, colorectal cancer, hepatocellular cancer, prostate cancer, gastric cancer, etc. Our research provides direction and basis for future research in this field, as well as technical and knowledge basis support for experts and researchers in related medical fields.

“…In recent years, the rise of the concept of knowledge service has provided a new way of thinking for vocational education and work assistance [8]. As a systematic and convenient way of offering knowledge and solutions, the knowledge service meets multiple needs of users including querying information, gaining knowledge, searching aid [9][10][11], and has been applied in library, medicine, geography and many other fields [12][13][14][15]. For instance, a domestic knowledge service platform was constructed by the State Grid Electric Power Research Institute (SGEPRI) to share latest news, papers, patents, standards and policies in the electric power field [16].…”

The development of knowledge management and service enlightens the upgrading of traditional vocational education and work assistance. This work focuses on the field of substation and proposes a novel knowledge service method based on the domain knowledge graph. Specifically, a systematic three-layer knowledge graph is constructed, reflecting the physical entity, specialized knowledge and basic knowledge in substations. Furthermore, a domain model is established to translate the user’s demand into a node set derived from the knowledge graph, and a path model is established to give a sequence of the derived nodes for recommendation. The results have been validated logical and reasonable in different scenarios of learning, training and getting assistance. Taking advantage of the structure and precision of our knowledge graph, more applications can be added into the substation-related services.
